127-703: Amstrad was a British consumer electronics company, founded in 1968 by Alan Sugar . During the 1980s, the company was known for its home computers beginning with the Amstrad CPC and later also the ZX Spectrum range after the Sinclair deal, which led it to have a substantial share of the PC market in Britain. In the following decade it shifted focus towards communication technologies, and its main business during

254-561: A radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator , which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called cellular telephones or cell phones in North America. In addition to telephony , digital mobile phones ( 2G ) support

381-458: A relocatable format using the filename extension .CMD to avoid name conflicts with CP/M-80 and MS-DOS .COM files. MS-DOS version 1.0 added a more advanced relocatable . EXE executable file format. Most of the machines in the early days of MS-DOS had differing system architectures and there was a certain degree of incompatibility, and subsequently vendor lock-in . Users who began using MS-DOS with their machines were compelled to continue using

508-618: A 1994 settlement agreement limiting Microsoft to per-copy licensing. Digital Research did not gain by this settlement, and years later its successor in interest, Caldera , sued Microsoft for damages in the Caldera v. Microsoft lawsuit. It was believed that the settlement ran in the order of $ 150 million , but was revealed in November 2009 with the release of the Settlement Agreement to be $ 280 million . Microsoft also used

635-448: A DOS startup disk on Windows Vista , the files on the startup disk are dated April 18, 2005, but are otherwise unchanged, including the string "MS-DOS Version 8 Copyright 1981–1999 Microsoft Corp" inside COMMAND.COM . Windows 7, 8, and 8.1 can also create a MS-DOS startup disk. Starting with Windows 10 , the ability to create a MS-DOS startup disk has been removed, and so either a virtual machine running MS-DOS or an older version (in

762-516: A Graphical User Interface (GUI) on top of MS-DOS. With Windows 95 , 98 , and Me , the role of MS-DOS was reduced to a boot loader according to Microsoft, with MS-DOS programs running in a virtual DOS machine within 32-bit Windows, with ability to boot directly into MS-DOS retained as a backward compatibility option for applications that required real mode access to the hardware, which was generally not possible within Windows. The command line accessed

889-812: A communications protocol is a system of digital rules for data exchange within or between computers. The Consumer Electronics Show (CES) trade show has taken place yearly in Las Vegas , Nevada since its foundation in 1973. The event, which grew from having 100 exhibitors in its inaugural year to more than 4,500 exhibiting companies in its 2020 edition, features the latest in consumer electronics, speeches by industry experts and innovation awards. The IFA Berlin trade show has taken place in Berlin , Germany since its foundation in 1924. The event features new consumer electronics and speeches by industry pioneers. Institute of Electrical and Electronics Engineers (IEEE),

1016-755: A copy of the Windows Me boot disk, stripped down to bootstrap only. This is accessible only by formatting a floppy as an "MS-DOS startup disk". Files like the driver for the CD-ROM support were deleted from the Windows Me bootdisk and the startup files ( AUTOEXEC.BAT and CONFIG.SYS ) no longer had content. This modified disk was the base for creating the MS-DOS image for Windows XP. Some of the deleted files can be recovered with an undelete tool. When booting up an MS-DOS startup disk made with Windows XP's format tool,

1143-541: A forceful letter to PC Week (November 5, 1990), denying that Microsoft was engaged in FUD tactics ("to serve our customers better, we decided to be more forthcoming about version 5.0") and denying that Microsoft copied features from DR DOS: "The feature enhancements of MS-DOS version 5.0 were decided and development was begun long before we heard about DR DOS 5.0. There will be some similar features. With 50 million MS-DOS users, it shouldn't be surprising that DRI has heard some of

1270-423: A given price, semiconductor functionality doubles every two years. While consumer electronics continues in its trend of convergence , combining elements of many products, consumers face different purchasing decisions. There is an ever-increasing need to keep product information updated and comparable for the consumer to make an informed choice. Style, price, specification, and performance are all relevant. There are

1397-495: A gradual shift towards e-commerce web-storefronts. Many products include Internet access using technologies such as Wi-Fi , Bluetooth , EDGE , or Ethernet . Products not traditionally associated with computer use (such as TVs or hi-fi equipment) now provide options to connect to the Internet or to a computer using a home network to provide access to digital content. The desire for high-definition (HD) content has led

1524-448: A higher price. Executable programs for CP/M-86 and MS-DOS were not interchangeable with each other; many applications were sold in both MS-DOS and CP/M-86 versions until MS-DOS became preponderant (later Digital Research operating systems could run both MS-DOS and CP/M-86 software). MS-DOS originally supported the simple .COM , which was modeled after a similar but binary-incompatible format known from CP/M-80 . CP/M-86 instead supported

1651-458: A large share of the business computer market. Microsoft and IBM together began what was intended as the follow-on to MS-DOS/PC DOS, called OS/2 . When OS/2 was released in 1987, Microsoft began an advertising campaign announcing that "DOS is Dead" and stating that version 4 was the last full release. OS/2 was designed for efficient multi-tasking and offered a number of advanced features that had been designed together with similar look and feel ; it

1778-407: A number of MOSFET integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer , proximity sensors , barometer , gyroscope , accelerometer and more ), and support wireless communications protocols (such as Bluetooth , Wi-Fi , or satellite navigation ). In 2017, Greenpeace USA published a study of 17 of

1905-407: A particular model), or per-copy (a fee for each copy of MS-DOS installed). The largest manufacturers used the per-processor arrangement, which had the lowest fee. This arrangement made it expensive for the large manufacturers to migrate to any other operating system, such as DR DOS. In 1991, the U.S. government Federal Trade Commission began investigating Microsoft's licensing procedures, resulting in

2032-529: A potential shift in attitudes to reuse and repair. With turnover of small household appliances high and costs relatively low, many consumers will throw unwanted electric goods in the normal dustbin, meaning that items of potentially high reuse or recycling value go to landfills. While more oversized items such as washing machines are usually collected, it has been estimated that the 160,000 tonnes of EEE in regular waste collections were worth £220   million. And 23% of EEE taken to Household Waste Recycling Centres

2159-446: A result, the big players rely on global markets to achieve economies of scale. Even these companies sometimes have to cooperate with each other, for instance on standards, to reduce the risk of their investments. In supply chain management , there is much discussion on risks related to such aspects of supply chains as short product life cycles, high competition combined with cooperation, and globalization. The consumer electronics industry

2286-441: A single substrate using electrical connections between circuits within the chip itself. IC technology led to more advanced and cheaper consumer electronics, such as transistorized televisions, pocket calculators , and by the 1980s, affordable video game consoles and personal computers that regular middle-class families could buy. Starting in the 1980s with the compact disc and the introduction of personal computers, and until

2413-513: A standard Microsoft kernel, which they would typically supply on disk to end users along with the hardware. Thus, there were many different versions of "MS-DOS" for different hardware, and there is a major distinction between an IBM-compatible (or ISA) machine and an MS-DOS [compatible] machine. Some machines, like the Tandy 2000 , were MS-DOS compatible but not IBM-compatible, so they could run software written exclusively for MS-DOS without dependence on

2540-571: A takeover of Amstrad for £125m, a 23.7% premium on its market capitalisation. BSkyB had been a major client of Amstrad, accounting for 75% of sales for its 'set top box' business. Having supplied BSkyB with hardware since its inception in 1988, market analysts had noted the two companies becoming increasingly close. Sky bought Amstrad so they could have their own hardware development division to develop new satellite boxes ( Sky Q ) made in-house. Under Sky, Amstrad only produced satellite receivers for Sky, as doing so allows them to reduce costs by cutting out

2667-599: A tiny fraction of disposable income , rising from 0.5   percent in the US in 1920, to about 2   percent in 1980. Yet the sequence of electrical and mechanical durables have altered the activities and experiences of households in America and Britain in the twentieth century. With the expansion of cookers, vacuum cleaners, refrigerators, washing machines, radios, televisions, air conditioning, and microwave ovens, households have gained an escalating number of appliances. Despite

2794-413: A variety of other services , such as text messaging , MMS , email , Internet access , short-range wireless communications ( infrared , Bluetooth ), business applications, video games and digital photography . Mobile phones offering only those capabilities are known as feature phones ; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones . A smartphone

2921-602: A variety of other computers based on various other processors were in serious competition with the IBM PC: the Apple II , Mac , Commodore 64 and others did not use the 808x processor; many 808x machines of different architectures used custom versions of MS-DOS. At first all these machines were in competition. In time the IBM PC hardware configuration became dominant in the 808x market as software written to communicate directly with

3048-450: A variety of tactics in MS-DOS and several of their applications and development tools that, while operating perfectly when running on genuine MS-DOS (and PC DOS), would break when run on another vendor's implementation of DOS. Notable examples of this practice included: All versions of Microsoft Windows have had an MS-DOS or MS-DOS-like command-line interface called MS-DOS Prompt which redirected input to MS-DOS and output from MS-DOS to

3175-779: A videocassette recorders (VCRs) consume more electricity during the course of a year in standby mode than when they are used to record or playback videos. Similar findings were obtained concerning satellite boxes , which consume almost the same amount of energy in "on" and "off" modes. A 2012 study in the United Kingdom, carried out by the Energy Saving Trust , found that the devices using the most power on standby mode included televisions, satellite boxes, and other video and audio equipment. The study concluded that UK households could save up to £86 per year by switching devices off instead of using standby mode. A report from

3302-456: A virtual machine or dual boot) must be used to format a floppy disk, or an image must be obtained from an external source. Other solutions include using DOS compatible alternatives, such as FreeDOS or even copying the required files and boot sector themselves. The last remaining components related to MS-DOS was the NTVDM component, which was removed entirely in Windows starting with Windows 11 as

3429-510: Is a portable device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems , which facilitate wider software , internet (including web navigation over mobile broadband ), and multimedia functionality (including music, video, cameras , and gaming ), alongside core phone functions such as voice calls and text messaging . Smartphones typically contain

3556-609: Is a subsidiary of Samsung Electronics contributing $ 1.2   billion in revenues. Samsung Electronics has one of the highest R&D expenditure as a proportion of revenues in the industry and spent about $ 2.9   billion in 2003. Along with its competitors, Samsung Electronics is global and employs 88,000 people in 89 offices in 46 countries. Not including facilities in Korea, it has 24 manufacturing complexes, 40 distribution bases and 15 branches spread over all continents except Antarctica. Countries with manufacturing facilities include

3683-422: Is an operating system for x86 -based personal computers mostly developed by Microsoft . Collectively, MS-DOS, its rebranding as IBM PC DOS , and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system ). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it

3810-603: Is comparable across countries affects the extent of the gains from international integration. In addition, consumer preferences change over time to disturb existing patterns of behavior. A feature of some industries is that demand for variety increases as the market moves from first-time buying to replacement demand. A resource to further understand this idea of consumer preferences can be observed through Lizabeth Cohen's book titled, "A Consumers' Republic", "Only if we have large demands can we expect large production". The electronics industry, especially consumer electronics, emerged in

3937-402: Is in its 35th year. Institute of Electrical and Electronics Engineers (IEEE) Computer Society also have initiated a conference to research on next generation consumer electronics as Smart Electronics. The conference named IEEE Symposium on Smart Electronics Systems ( IEEE-iSES ) is on its 9th year. Electronics retailing is a significant part of the retail industry in many countries. In

4064-626: Is limited and energy intensive. Electronic waste describes discarded electrical or electronic devices. Many consumer electronics may contain toxic minerals and elements, and many electronic scrap components, such as CRTs , may contain contaminants such as lead , cadmium , beryllium , mercury , dioxins , or brominated flame retardants . Electronic waste recycling may involve significant risk to workers and communities and great care must be taken to avoid unsafe exposure in recycling operations and leaking of materials such as heavy metals from landfills and incinerator ashes. However, large amounts of

4191-412: Is mainly for education and experimentation with historic operating systems and for new programmers to gain an understanding of how low-level software works, both historic and current. According to program manager Rich Turner, the other versions could not be open-sourced due to third-party licensing restrictions. Due to the historical nature of the software, Microsoft will not accept any pull requests to

4318-518: Is often called the MS-DOS Prompt. In part, this was the official name for it in Windows 9x and early versions of Windows NT (NT 3.5 and earlier), and in part because the SoftPC emulation of DOS redirects output into it. Actually only COMMAND.COM and other 16-bit commands run in an NTVDM with AUTOEXEC.NT and CONFIG.NT initialization determined by _DEFAULT.PIF , optionally permitting

4445-486: Is part of the wider electronics industry . In turn, the driving force behind the electronics industry is the semiconductor industry . For its first fifty years, the phonograph turntable did not use electronics; the needle and sound horn were purely mechanical technologies. However, in the 1920s, radio broadcasting became the basis of mass production of radio receivers . The vacuum tubes that had made radios practical were used with record players as well, to amplify

4572-441: Is still used in embedded x86 systems due to its simple architecture and minimal memory and processor requirements, though some current products have switched to the still-maintained open-source alternative FreeDOS . In 2018, Microsoft released the source code for MS-DOS 1.25 and 2.0 on GitHub , with the source code for MS-DOS 4.00 being released in the same repository six years later. The purpose of this, according to Microsoft,

4699-620: Is the very embodiment of these aspects of supply chain management and related risks. While some of the supply and demand related risks are similar to such industries as the toy industry, the consumer electronics industry faces additional risks due to its vertically integrated supply chains. There are also numerous supply-chain-wide contextual risks that cut across the supply chain especially impacting companies with global supply chains. These include cultural differences in multinational operations, environmental risk, regulations risk, and exchange rate risk across multiple countries. Whether or not demand

4826-422: Is used to distinguish them from " white goods ", which are meant for housekeeping tasks, such as washing machines and refrigerators . In British English, they are often called brown goods by producers and sellers. In the 2010s, this distinction is absent in large big box consumer electronics stores , which sell entertainment, communication and home office devices, light fixtures and appliances, including

4953-513: Is used within some consumer electronics, such as mobile phones . This type of software may be embedded within the hardware of electronic devices. Some consumer electronics include software that is used on a personal computer in conjunction with electronic devices, such as camcorders and digital cameras , and third-party software for such devices also exists. Some consumer electronics adhere to protocols, such as connection protocols "to high speed bi-directional signals". In telecommunications ,

5080-668: The E-m@iler . This was followed by the E-m@iler Plus in 2002, and the E3 Videophone in 2004. Amstrad's UK E-m@iler business is operated through a separate company, Amserve Ltd which is 89.8% owned by Amstrad and 10.2% owned by DSG International plc (formerly Dixons plc). Amstrad has also produced a variety of home entertainment products over their history, including hi-fi, televisions, VCRs , and DVD players. In July 2007, British Sky Broadcasting (BSkyB) announced

5207-591: The Intel 8086 and 8088 processors, including the IBM PC and clones, the initial competition to the PC DOS/MS-DOS line came from Digital Research , whose CP/M operating system had inspired MS-DOS. In fact, there remains controversy as to whether QDOS was more or less plagiarized from early versions of CP/M code. Digital Research released CP/M-86 a few months after MS-DOS, and it was offered as an alternative to MS-DOS and Microsoft's licensing requirements, but at

5334-564: The International Energy Agency in 2014 found that $ 80   billion of power is wasted globally per year due to inefficiency of electronic devices. Consumers can reduce unwanted use of standby power by unplugging their devices, using power strips with switches, or by buying devices that are standardized for better energy management, particularly Energy Star -marked products. A high number of different metals and low concentration rates in electronics means that recycling

5461-698: The LocoScript word processing program. They were also capable of running the CP/M operating system. The Amsoft division of Amstrad was set up to provide in-house software and consumables. On 7 April 1986 Amstrad announced it had bought from Sinclair Research "the worldwide rights to sell and manufacture all existing and future Sinclair computers and computer products, together with the Sinclair brand name and those intellectual property rights where they relate to computers and computer related products", which included

5588-728: The PPC512 and 640 models, introduced a year before the Macintosh Portable . They ran MS-DOS on an 8 MHz processor, and the built-in screen could emulate the Monochrome Display Adapter or Color Graphics Adapter . Amstrad's final (and ill-fated) attempts to exploit the Sinclair brand were based on the company's own PCs; a compact desktop PC derived from the PPC 512, branded as the Sinclair PC200 , and

5715-705: The PenPad , a PDA similar to the Apple Newton , and released only weeks before it. It was a commercial failure, and had several technical and usability problems. It lacked most features that the Apple Newton included, but had a lower price at $ 450. As Amstrad began to concentrate less on computers and more in communication, they purchased several telecommunications businesses including Betacom , Dancall Telecom, Viglen Computers , and modem manufacturer Dataflex Design Communications, bought out of liquidation, during

5842-581: The Santa Cruz Operation (SCO). On March 25, 2014, Microsoft made the code to SCP MS-DOS 1.25 and a mixture of Altos MS-DOS 2.11 and TeleVideo PC DOS 2.11 available to the public under the Microsoft Research License Agreement , which makes the code source-available , but not open source as defined by Open Source Initiative or Free Software Foundation standards. Microsoft would later re-license

5969-739: The Windows NT -derived 32-bit operating systems ( Windows NT , 2000 , XP and newer), developed alongside the 9x series, do not contain MS-DOS compatibility as a core component of the operating system nor do they rely on it for bootstrapping, as NT was not with the level of support for legacy MS-DOS and Win16 apps that Windows 9x was, but does provide limited DOS emulation called NTVDM (NT Virtual DOS Machine) to run DOS applications and provide DOS-like command prompt windows. 64-bit versions of Windows NT prior to Windows 11 (and Windows Server 2008 R2 by extension) do not provide DOS emulation and cannot run DOS applications natively. Windows XP contains

6096-596: The ZX Spectrum , for £5 million. This included Sinclair's unsold stock of Sinclair QLs and Spectrums. Amstrad made more than £5 million on selling these surplus machines alone. Amstrad launched two new variants of the Spectrum: the ZX Spectrum +2, based on the ZX Spectrum 128, with a built-in cassette tape drive (like the CPC 464) and, the following year, the ZX Spectrum +3, with a built-in floppy disk drive (similar to

6223-441: The ubiquity of these goods, their diffusion is not well understood. Some types of appliances diffuse more frequently than others. In particular, home entertainment appliances such as radio and television have diffused much faster than household and kitchen machines." Consumer electronics devices include those used for Increasingly consumer electronics products such as digital distribution of video games have become based on

6350-618: The vacuum forming process. Amstrad expanded to the marketing of low cost amplifiers and tuners , imported from East Asia and badged with the Amstrad name for the UK market. Their first electrical product was the Amstrad 8000 amplifier. In 1980, Amstrad went public trading on the London Stock Exchange , and doubled in size each year during the early '80s. Amstrad began marketing its own home computers in an attempt to capture

6477-748: The "pre-announcement" of MS-DOS 6.0 again stifled the sales of DR DOS. Microsoft had been accused of carefully orchestrating leaks about future versions of MS-DOS in an attempt to create what in the industry is called FUD ( fear, uncertainty, and doubt ) regarding DR DOS. For example, in October 1990, shortly after the release of DR DOS 5.0, and long before the eventual June 1991 release of MS-DOS 5.0, stories on feature enhancements in MS-DOS started to appear in InfoWorld and PC Week . Brad Silverberg , then Vice President of Systems Software at Microsoft and general manager of its Windows and MS-DOS Business Unit, wrote

Some of the newer products sold include virtual reality head-mounted display goggles, smart home devices that connect home devices to the Internet , streaming devices, and wearable technology . In

6731-451: The 1994 release of MS-DOS 6.21, which had disk compression removed. Shortly afterwards came version 6.22, with a new version of the disk compression system, DriveSpace, which had a different compression algorithm to avoid the infringing code. Prior to 1995, Microsoft licensed MS-DOS (and Windows) to computer manufacturers under three types of agreement: per-processor (a fee for each system the company sold), per-system (a fee for each system of

6858-456: The 2000s was the manufacture of satellite television set-top boxes for Sky , which Amstrad had started in 1989 as the then sole supplier of the emerging Sky TV service. Headquartered in Brentwood , the company was listed on the London Stock Exchange from 1980 to 2008, the year when Sugar stepped down after 40 years. After acquiring Betacom and Viglen , Amstrad was broken up in 1997 but

6985-520: The 2010s, most consumer electronics have become based on digital technologies. They have essentially merged with the computer industry in what is increasingly referred to as the consumerization of information technology . Some consumer electronics stores have also begun selling office and baby furniture . Consumer electronics stores may be " brick and mortar " physical retail stores, online stores, or combinations of both. Annual consumer electronics sales are expected to reach $ 2.9 trillion by 2020. It

7112-571: The 20th century and has become a global industry worth billions of dollars. Contemporary society uses all manner of electronic devices built-in automated or semi-automated factories operated by the industry. Most consumer electronics are built in China, due to maintenance cost, availability of materials, quality, and speed as opposed to other countries such as the United States. Cities such as Shenzhen have become important production centres for

7239-670: The CPC 664 and 6128), taking the 3" disks that many Amstrad machines used. In 1986 Amstrad entered the IBM PC-compatible arena with the PC1512 system. In standard Amstrad livery and priced at £399 it was a success, capturing more than 25% of the European computer market. It was MS-DOS -based, but with the GEM graphics interface, and later Windows . In 1988 Amstrad attempted to make the first affordable portable personal computer with

7366-561: The DOS command line (usually COMMAND.COM ) through a Windows module (WINOLDAP.MOD). Windows NT-based operating systems boot to a kernel whose purpose is to load Windows and run the system. One cannot run Win32 applications in the loader system in the manner that OS/2, UNIX or consumer versions of Windows can launch character-mode sessions. The command session permits running various supported command-line utilities from Win32, MS-DOS, OS/2 1.x and POSIX. The emulators for MS-DOS, OS/2 and POSIX use

7493-633: The European PC market. Amstrad had been a major supplier of set top boxes to UK satellite television pay-TV provider Sky since its launch in 1989 following the launch of the SES Astra 1A TV satellite. Amstrad was key to the introduction of Sky, as the company was responsible for finding methods to produce the requisite equipment at an attractive price for the consumer - Alan Sugar famously approached "someone who bashes out dustbin lids", to manufacture mesh satellite dishes cheaply. Ultimately, it

7620-524: The IBM 5150 or the IBM PC . Within a year, Microsoft licensed MS-DOS to over 70 other companies. It was designed to be an OS that could run on any 8086-family computer. Each computer would have its own distinct hardware and its own version of MS-DOS, similar to the situation that existed for CP/M , and with MS-DOS emulating the same solution as CP/M to adapt for different hardware platforms. To this end, MS-DOS

7747-470: The MS-DOS Prompt, or, in later versions, Command Prompt . This could run many DOS and variously Win32, OS/2 1.x and POSIX command-line utilities in the same command-line session, allowing piping between commands. The user interface, and the icon up to Windows 2000, followed the native MS-DOS interface. The Command Prompt introduced with Windows NT is not actually MS-DOS, but shares some commands with MS-DOS. The 16-bit versions of Windows (up to 3.11) ran as

7874-434: The MS-DOS name for all versions but the IBM one, which was originally called "IBM Personal Computer DOS", later shortened to IBM PC DOS . (Competitors released compatible DOS systems such as DR-DOS and PTS-DOS that could also run MS-DOS applications.) In the former Eastern bloc , MS-DOS derivatives named DCP ( Disk Control Program  [ de ] ) 3.20 and 3.30 (DCP 1700, DCP 3.3) and WDOS existed in

There are alternatives such as virtual machine emulators such as Microsoft's own Virtual PC , as well as VMware , DOSBox etc., unofficial compatibility layers such as NTVDMx64, OTVDM (WineVDM), Win3mu and others. The introduction of Windows 3.0 in 1990, with an easy-to-use graphical user interface , marked

8128-549: The PC hardware without using standard operating system calls ran much faster, but on true PC-compatibles only. Non-PC-compatible 808x machines were too small a market to have fast software written for them alone, and the market remained open only for IBM PCs and machines that closely imitated their architecture, all running either a single version of MS-DOS compatible only with PCs, or the equivalent IBM PC DOS. Most clones cost much less than IBM-branded machines of similar performance, and became widely used by home users, while IBM PCs had

8255-692: The PC1512 rebadged as the Sinclair PC500. Amstrad's second generation of PCs, the PC2000 series, were launched in 1989. However, due to a problem with the Seagate ST277R hard disk shipped with the PC2386 model, these had to be recalled and fitted with Western Digital controllers. Amstrad later successfully sued Seagate, but following bad press over the hard disk problems, Amstrad lost its lead in

8382-477: The US, Malaysia, China, India, and Hungary. The increase in popularity of such domestic appliances as ' white goods ' is a characteristic element of consumption patterns during the golden age of the Western economy. Europe's White Goods industry has evolved over the past 40 years, first by changing tariff barriers, and later by technical and demand shifts. The spending on domestic appliances has claimed only

8509-597: The United States, dedicated consumer electronics stores have mostly given way to big-box stores such as Best Buy , the largest consumer electronics retailer in the country, although smaller dedicated stores include Apple Stores , and specialist stores that serve, for example, audiophiles and exceptions, such as the single-branch B&H Photo store in New York City. Broad-based retailers, such as Walmart and Target , also sell consumer electronics in many of their stores. In April 2014, retail e-commerce sales were

Windows Me removed the capability to boot its underlying MS-DOS 8.0 alone from a hard disk, but retained the ability to make a DOS boot floppy disk (called an "Emergency Boot Disk") and can be hacked to restore full access to the underlying DOS. On December 31, 2001, Microsoft declared all versions of MS-DOS 6.22 and older obsolete and stopped providing support and updates for

8763-524: The affordable Amstrad receiver with the typical black mesh minidish were sold in large numbers. In the early 1990s, Amstrad began to focus on portable computers rather than desktop computers . In 1990, Amstrad tried to enter the video game console market with the Amstrad GX4000 , similar to what Commodore did at the same time with the C64 GS . The console, based on the Amstrad 464 Plus hardware,

8890-424: The background for loading Windows 9x . MS-DOS was a renamed form of 86-DOS  – owned by Seattle Computer Products , written by Tim Paterson . Development of 86-DOS took only six weeks, as it was basically a clone of Digital Research 's CP/M (for 8080/Z80 processors), ported to run on 8086 processors and with two notable differences compared to CP/M: an improved disk sector buffering logic, and

9017-592: The bathroom type. Radio broadcasting in the early 20th century brought the first major consumer product, the broadcast receiver . Later products included telephones , televisions , and calculators , then audio and video recorders and players, video game consoles , mobile phones , personal computers and MP3 players . In the 2010s, consumer electronics stores often sell GPS , automotive electronics ( vehicle audio ), video game consoles , electronic musical instruments (e.g., synthesizer keyboards), karaoke machines, digital cameras , and video players ( VCRs in

9144-496: The beginning of the end for the command-line driven MS-DOS. With the release of Windows 95 (and continuing in the Windows 9x product line through to Windows Me ), an integrated version of MS-DOS was used for bootstrapping , troubleshooting, and backwards-compatibility with old DOS software, particularly games, and no longer released as a standalone product. In Windows 95, the DOS, called MS-DOS 7, can be booted separately, without

9271-666: The code under the MIT License on September 28, 2018, making these versions free software . Microsoft later released the code for MS-DOS 4.00 on April 25, 2024, under the same license. As an April Fool's Day joke in 2015, Microsoft Mobile launched a Windows Phone application called MS-DOS Mobile which was presented as a new mobile operating system and worked similar to MS-DOS. Microsoft licensed or released versions of MS-DOS under different names like Lifeboat Associates "Software Bus 86" a.k.a. SB-DOS , COMPAQ-DOS , NCR-DOS or Z-DOS before it eventually enforced

9398-541: The earliest transistors at Bell led to transistor radios . This led to the emergence of the home entertainment consumer electronics industry starting in the 1950s, largely due to the efforts of Tokyo Tsushin Kogyo (now Sony ) in successfully commercializing transistor technology for a mass market, with affordable transistor radios and then transistorized television sets . Integrated circuits (ICs) followed when manufacturers built circuits (usually for military purposes) on

9525-498: The early 1990s. The company also established a direct marketing channel, Amstrad Direct, in late 1994 and announced 486- and Pentium-based products including an " All-in-One Multimedia PC" with built-in television tuner, infra-red remote control, amplifier and speakers. A pen-based personal digital assistant with support for a PCMCIA-based modem, the InfoPad, was also unveiled with a September 1995 launch scheduled. By 1996, Alan Sugar

9652-426: The early 2000s, many consumer electronics devices such as televisions and stereo systems, were digitized: digital computer technology, and thus digital signals, were integrated into the operation of consumer electronics devices, drastically changing their operation but with improved results such as improved image quality in televisions. This was made possible by Moore's law . In 2004, the consumer electronics industry

9779-560: The highest in the consumer electronic and computer categories as well. Some consumer electronics retailers offer extended warranties on products with programs such as SquareTrade . An electronics district is an area of commerce with a high density of retail stores that sell consumer electronics. Consumer electronic service can refer to the maintenance of said products. When consumer electronics have malfunctions, they may sometimes be repaired. In 2013, in Pittsburgh, Pennsylvania,

9906-511: The host's window in the same way that Win16 applications use the Win32 explorer. Using the host's window allows one to pipe output between emulations. The MS-DOS emulation takes place through the NTVDM (NT Virtual DOS Machine). This is a modified SoftPC (a former product similar to VirtualPC ), running a modified MS-DOS 5 (NTIO.SYS and NTDOS.SYS). The output is handled by the console DLLs, so that

10033-424: The increased popularity in listening to sound from analog audio devices, such as phonographs , as opposed to digital sound, has sparked a noticeable increase of business for the electronic repair industry there. A mobile phone , cellular phone, cell phone, cellphone, handphone, or hand phone, sometimes shortened to simply mobile, cell or just phone, is a portable telephone that can make and receive calls over

10160-523: The industry to develop a number of technologies, such as WirelessHD or ITU-T G.hn , which are optimized for distribution of HD content between consumer electronic devices in a home. The consumer electronics industry faces consumers with unpredictable tastes on the demand side, supplier-related delays or disruptions on the supply side, and production challenges occurring in the process. The high rate of technology evolution or revolution requires large investments without any guarantee of profitable returns. As

10287-548: The industry, attracting many consumer electronics companies such as Apple Inc. An electronic component is any essential discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form, and are not to be confused with electrical elements , conceptual abstractions representing idealized electronic components. Consumer electronics such as personal computers use various types of software. Embedded software

10414-598: The internet and digital technologies. The consumer electronics industry has primarily merged with the software industry in what is increasingly referred to as the consumerization of information technology . One overriding characteristic of consumer electronic products is the trend of ever-falling prices. This is driven by gains in manufacturing efficiency and automation , lower labor costs as manufacturing has moved to lower-wage countries, and improvements in semiconductor design. Semiconductor components benefit from Moore's law , an observed principle which states that, for

10541-701: The introduction of FAT12 instead of the CP/M filesystem . This first version was shipped in August 1980. Microsoft, which needed an operating system for the IBM Personal Computer , hired Tim Paterson in May 1981 and bought 86-DOS 1.10 for US$ 25,000 in July of the same year. Microsoft kept the version number, but renamed it MS-DOS. They also licensed MS-DOS 1.10/1.14 to IBM, which, in August 1981, offered it as PC DOS 1.0 as one of three operating systems for

10668-699: The late 1980s. They were produced by the East German electronics manufacturer VEB Robotron . The following versions of MS-DOS were released to the public: Support for IBM's XT 10 MB hard disk drives, support up to 16 MB or 32 MB FAT12 -formatted hard disk drives depending on the formatting tool shipped by OEMs, user-installable device drivers, tree-structure filing system, Unix-like inheritable redirectable file handles, non-multitasking child processes an improved Terminate and Stay Resident (TSR) API, environment variables, device driver support, FOR and GOTO loops in batch files, ANSI.SYS . Microsoft DOS

10795-402: The limits of their contemporary hardware. Very soon an IBM-compatible architecture became the goal, and before long all 8086-family computers closely emulated IBM's hardware , and only a single version of MS-DOS for a fixed hardware platform was needed for the market. This version is the version of MS-DOS that is discussed here, as the dozens of other OEM versions of "MS-DOS" were only relevant to

10922-469: The market from Commodore and Sinclair , with the Amstrad CPC range in 1984. The CPC 464 was launched in the UK, Ireland, France, Australia, New Zealand, Germany, Spain and Italy. It was followed by the CPC 664 and CPC 6128 models. Later "Plus" variants of the 464 and 6128, launched in 1990, increased their functionality slightly. In 1985, the popular Amstrad PCW range was introduced, which were principally word processors , complete with printer, running

11049-470: The middleman. Its main competitor in this space was Pace plc . Sugar commented that he wished to play a part in the business, saying: "I turn 60 this year and I have had 40 years of hustling in the business, but now I have to start thinking about my team of loyal staff, many of whom have been with me for many years." It was announced on 2 July 2008 that Sugar had stepped down as Chairman of Amstrad, which had been planned since BSkyB took over in 2007. Amstrad

11176-419: The name of the original company being AMS Trading (Amstrad) Limited, derived from its founder's initials (Alan Michael Sugar). Amstrad entered the market in the field of consumer electronics . During the 1970s they were at the forefront of low-priced hi-fi, TV and car stereo cassette technologies. Lower prices were achieved by injection moulding plastic hi-fi turntable covers, undercutting competitors who used

11303-406: The name was soon revived when successor Betacom plc renamed itself to Amstrad plc. Amstrad was a FTSE 100 Index constituent up until the company was acquired by BSkyB in 2007 for £125 million. In 2010, Sky integrated Amstrad's satellite division as part of Sky so they could make their own set-top boxes in-house. Amstrad (also known as AMSTrad) was founded in 1968 by Alan Sugar at the age of 21,

11430-524: The ones using electronics the most. "People who frequently use their thumbs to type text messages on cell phones can develop a painful affliction called De Quervain syndrome that affects their tendons on their hands. The best-known disease in this category is called carpal tunnel syndrome , which results from pressure on the median nerve in the wrist". MS-DOS MS-DOS ( / ˌ ɛ m ˌ ɛ s ˈ d ɒ s / em-es- DOSS ; acronym for Microsoft Disk Operating System , also known as Microsoft DOS )

11557-561: The operating system dropped support for 32-bit processors in favor of being solely offered in 64-bit versions only. This effectively ended any association of MS-DOS within Microsoft Windows after 36 years. MS-DOS 6.22 was the last standalone version produced by Microsoft for Intel 8088 , Intel 8086 , and Intel 80286 processors, which remains available for download via their MSDN , volume license, and OEM license partner websites, for customers with valid login credentials. MS-DOS

11684-450: The parties failed to agree a price and a strategy to dispose of the group's other assets. In 1997, Amstrad PLC was wound up, its shares being split into Viglen and Betacom instead. Betacom PLC was then renamed Amstrad PLC. The same year, Amstrad supplied set top boxes to Australian broadcaster Foxtel , and in 2004 to Italian broadcaster Sky Italia . In 2000, Amstrad released the first of its combined telephony and email devices, called

11811-600: The period when Digital Research was competing in the operating system market some computers, like the Amstrad PC1512 , were sold with floppy disks for two operating systems (only one of which could be used at a time), MS-DOS and CP/M-86 or a derivative of it. Digital Research produced DOS Plus , which was compatible with MS-DOS 2.11, supported CP/M-86 programs, had additional features including multi-tasking, and could read and write disks in CP/M and MS-DOS format. While OS/2

11938-519: The peripheral hardware of the IBM PC architecture. This design would have worked well for compatibility, if application programs had only used MS-DOS services to perform device I/O. Indeed, the same design philosophy is embodied in Windows NT (see Hardware Abstraction Layer ). However, in MS-DOS' early days, the greater speed attainable by programs through direct control of hardware was of particular importance, especially for games, which often pushed

12065-455: The platform without Microsoft and sold it as the alternative to DOS and Windows. As a response to Digital Research 's DR DOS 6.0 , which bundled SuperStor disk compression, Microsoft opened negotiations with Stac Electronics , vendor of the most popular DOS disk compression tool, Stacker. In the due diligence process, Stac engineers had shown Microsoft part of the Stacker source code. Stac

12192-403: The produced electronic waste from developed countries is exported, and handled by the informal sector in countries like India, despite the fact that exporting electronic waste to them is illegal. Strong informal sector can be a problem for the safe and clean recycling. E-waste policy has gone through various incarnations since the 1970s, with emphases changing as the decades passed. More weight

12319-492: The program at the prompt ( CMD.EXE , 4NT.EXE , TCC.EXE ), can see the output. 64-bit Windows has neither the DOS emulation, nor the DOS commands EDIT, DEBUG and EDLIN that come with 32-bit Windows. The DOS version returns 5.00 or 5.50, depending on which API function is used to determine it. Utilities from MS-DOS 5.00 run in this emulation without modification. The very early beta programs of NT show MS-DOS 30.00, but programs running in MS-DOS 30.00 would assume that OS/2

12446-578: The raw materials. The energy consumption of consumer electronics and their environmental impact, either from their production processes or the disposal of the devices, is increasing steadily. EIA estimates that electronic devices and gadgets account for about 10%–15% of the energy use in American homes – largely because of their number; the average house has dozens of electronic devices. The energy consumption of consumer electronics increases – in America and Europe – to about 50% of household consumption if

12573-424: The same requests from customers that we have." – (Schulman et al. 1994). The pact between Microsoft and IBM to promote OS/2 began to fall apart in 1990 when Windows 3.0 became a marketplace success. Many of Microsoft's further contributions to OS/2 also went into creating a third GUI replacement for DOS, Windows NT . IBM, which had already been developing the next version of OS/2, carried on development of

12700-521: The shared features of its "single-user OS" and "the multi-user, multi-tasking , UNIX -derived operating system", and promising easy porting between them. After the breakup of the Bell System , however, AT&T Computer Systems started selling UNIX System V . Believing that it could not compete with AT&T in the Unix market, Microsoft abandoned Xenix, and in 1987 transferred ownership of Xenix to

12827-442: The sound so that it could be played through a loudspeaker . Television was soon invented but remained insignificant in the consumer market until the 1950s. The first working transistor , a point-contact transistor , was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, which led to significant research in the field of solid-state semiconductors in the early-1950s. The invention and development of

12954-881: The stigma for some of owning second-hand goods. But the benefits of reuse could allow lower-income households access to previously unaffordable technology while helping the environment at the same time. Desktop monitors and laptops produce major physical health concerns for humans when bodies are forced into unhealthy and uncomfortable positions to see the screen better. From this, neck and back pains and problems increase, commonly referred to as repetitive strain injuries . Using electronics before going to bed makes it difficult for people to fall asleep, hurting human health. Sleeping less prevents people from performing to their full potential physically and mentally and can also "increase rates of obesity and diabetes", which are "long-term health consequences". Obesity and diabetes are more commonly seen in students and in youth because they tend to be

13081-401: The system. As MS-DOS 7.0 was a part of Windows 95, support for it also ended when Windows 95 extended support ended on December 31, 2001. As MS-DOS 7.10 and MS-DOS 8.0 were part of Windows 98 and Windows ME, respectively, support ended when Windows 98 and ME extended support ended on July 11, 2006, thus ending support and updates of MS-DOS from Microsoft. In contrast to the Windows 9x series,

13208-519: The systems they were designed for, and in any case were very similar in function and capability to some standard version for the IBM PC—often the same-numbered version, but not always, since some OEMs used their own proprietary version numbering schemes (e.g. labeling later releases of MS-DOS 1.x as 2.0 or vice versa)—with a few notable exceptions. Microsoft omitted multi-user support from MS-DOS because Microsoft's Unix -based operating system, Xenix ,

13335-418: The term is redefined to include home appliances such as refrigerators , dryers , clothes washers and dishwashers . Standby power – used by consumer electronics and appliances while they are turned off – accounts for 5–10% of total household energy consumption, costing $ 100 annually to the average household in the United States. A study by United States Department of Energy 's Berkeley Lab found that

13462-474: The use of Win32 console applications and internal commands with an NTCMDPROMPT directive. Win32 console applications use CMD.EXE as their command prompt shell. This confusion does not exist under OS/2 because there are separate DOS and OS/2 prompts, and running a DOS program under OS/2 will launch a separate DOS window to run the application. All versions of Windows for Itanium (no longer sold by Microsoft) and x86-64 architectures no longer include

13589-478: The version customized for their hardware, or face trying to get all of their proprietary hardware and software to work with the new system. In the business world, the 808x-based machines that MS-DOS was tied to faced competition from the Unix operating system; the latter ran on many different hardware architectures. Microsoft itself sold a version of Unix for the PC called Xenix . In the emerging world of home users,

13716-612: The version number and the VER internal command reports as "Windows Millennium" and "5.1", respectively, and not as "MS-DOS 8.0" (which was used as the base for Windows Me but never released as a stand-alone product), though the API still says Version 8.0. The creation of the MS-DOS startup disk was then carried over to later versions of Windows, with the majority of its contents remaining unchanged from its introduction in Windows XP. When creating

13843-611: The world's largest professional society, has many initiatives to advance the state of the art of consumer electronics. IEEE has a dedicated society of thousands of professionals to promote CE, called the Consumer Electronics Society (CESoc). IEEE has multiple periodicals and international conferences to promote CE and encourage collaborative research and development in CE. The flagship conference of CESoc, called IEEE International Conference on Consumer Electronics (ICCE),

13970-438: The world's leading consumer electronics companies about their energy and resource consumption and the use of chemicals. Electronic devices use thousands rare metals and rare earth elements (40 on average for a smartphone ), these material are extracted and refined using water and energy-intensive processes. These metals are also used in the renewable energy industry meaning that consumer electronics are directly competing for

14097-453: The x86 platform. Initially, MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well. Progressive version releases delivered support for other mass storage media in ever greater sizes and formats, along with added feature support for newer processors and rapidly evolving computer architectures. Ultimately, it

14224-654: Was a commercial failure, because it used outdated technology, and most games available for it were straight ports of CPC games that could be purchased for much less in their original format. In 1993, Amstrad was licensed by Sega to produce a system which was similar to the Sega TeraDrive , going by the name of the Amstrad Mega PC , to try to regain their image in the gaming market. The system didn't succeed as well as expected, mostly due to its high initial retail price of £999. In that same year, Amstrad released

14351-455: Was designed with a modular structure with internal device drivers (the DOS BIOS ), minimally for primary disk drives and the console, integrated with the kernel and loaded by the boot loader, and installable device drivers for other devices loaded and integrated at boot time. The OEM would use a development kit provided by Microsoft to build a version of MS-DOS with their basic I/O drivers and

14478-515: Was fully multi-user. The company planned, over time, to improve MS-DOS so it would be almost indistinguishable from single-user Xenix, or XEDOS , which would also run on the Motorola 68000 , Zilog Z8000 , and the LSI-11 ; they would be upwardly compatible with Xenix, which Byte in 1983 described as "the multi-user MS-DOS of the future". Microsoft advertised MS-DOS and Xenix together, listing

14605-417: Was gradually placed on the need to dispose of e-waste more carefully due to the toxic materials it may contain. There has also been recognition that various valuable metals and plastics from waste electrical equipment can be recycled for other uses. More recently, the desirability of reusing whole appliances has been foregrounded in the 'preparation for reuse' guidelines. The policy focus is slowly moving towards

14732-552: Was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS , several competing products were released for

14859-445: Was immediately resaleable – or would be with minor repairs or refurbishment. This indicates a lack of awareness among consumers about where and how to dispose of EEE and the potential value of things that are going in the bin. For the reuse and repair of electrical goods to increase substantially in the UK, some barriers must be overcome. These include people's mistrust of used equipment in terms of whether it will be functional, safe and

14986-657: Was in control. The OS/2 emulation is handled through OS2SS.EXE and OS2.EXE, and DOSCALLS.DLL. OS2.EXE is a version of the OS/2 shell (CMD.EXE), which passes commands down to the OS2SS.EXE, and input-output to the Windows NT shell. Windows 2000 was the last version of NT to support OS/2. The emulation is OS/2 1.30. POSIX is emulated through the POSIX shell, but no emulated shell; the commands are handled directly in CMD.EXE. The Command Prompt

15113-1212: Was released through the OEM channel, until Digital Research released DR-DOS 5.0 as a retail upgrade. With PC DOS 5.00.1, the IBM–Microsoft agreement started to end, and IBM entered the retail DOS market with IBM DOS 5.00.1, 5.02, 6.00 and PC DOS 6.1, 6.3, 7, 2000 and 7.1. Localized versions of MS-DOS existed for different markets. While Western issues of MS-DOS evolved around the same set of tools and drivers just with localized message languages and differing sets of supported codepages and keyboard layouts, some language versions were considerably different from Western issues and were adapted to run on localized PC hardware with additional BIOS services not available in Western PCs, support multiple hardware codepages for displays and printers, support DBCS, alternative input methods and graphics output. Affected issues include Japanese ( DOS/V ), Korean, Arabic (ADOS 3.3/5.0), Hebrew (HDOS 3.3/5.0), Russian ( RDOS 4.01 / 5.0 ) as well as some other Eastern European versions of DOS. On microcomputers based on

15240-502: Was reported as having been looking for a buyer for Amstrad "for some time". Amongst the group's assets, cumulatively valued at £200 million , the Dancall subsidiary was of particular interest to potential acquirer Psion , producer of handheld computer products, for its expertise in "GSM digital mobile phone functionality" and the potential to integrate such functionality into Psion's own product range. Despite "long drawn out negotiations",

15367-507: Was seen as the legitimate heir to the "kludgy" DOS platform. MS-DOS had grown in spurts, with many significant features being taken or duplicated from Microsoft's other products and operating systems. MS-DOS also grew by incorporating, by direct licensing or feature duplicating, the functionality of tools and utilities developed by independent companies, such as Norton Utilities , PC Tools ( Microsoft Anti-Virus ), QEMM expanded memory manager, Stacker disk compression , and others. During

15494-748: Was taken off the Stock Exchange on 9 October 2008. Amstrad has ceased operations as a trading company, and now exists in name only. Amstrad's former offices are now a Premier Inn Hotel. Consumer electronics Consumer electronics or home electronics are electronic ( analog or digital ) equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment , communications and recreation . These products are usually referred to as black goods in American English, due to many products being housed in black or dark casings. This term

15621-517: Was the key product in Microsoft's development from a programming language company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI. MS-DOS went through eight versions, until development ceased in 2000; version 6.22 from 1994 was the final standalone version, with versions 7 and 8 serving mostly in

15748-547: Was the only manufacturer producing receiver boxes and dishes at the system's launch, and continued to manufacture set top boxes for Sky, from analogue to digital including Sky's Sky+ digital video recorder . With the addition of the Astra 1B TV satellite in May 1991 even more TV programs were available in Central Europe. In former East Germany as well as in the parts of former West Germany that had no access to cable TV,

15875-506: Was under protracted development, Digital Research released the MS-DOS compatible DR-DOS 5.0, which included features only available as third-party add-ons for MS-DOS. Unwilling to lose any portion of the market, Microsoft responded by announcing the "pending" release of MS-DOS 5.0 in May 1990. This effectively killed most DR DOS sales until the actual release of MS-DOS 5.0 in June 1991. Digital Research brought out DR DOS 6.0, which sold well until

16002-592: Was unwilling to meet Microsoft's terms for licensing Stacker and withdrew from the negotiations. Microsoft chose to license Vertisoft's DoubleDisk, using it as the core for its DoubleSpace disk compression. MS-DOS 6.0 and 6.20 were released in 1993, both including the Microsoft DoubleSpace disk compression utility program. Stac successfully sued Microsoft for patent infringement regarding the compression algorithm used in DoubleSpace. This resulted in

16129-508: Was worth US$ 240   billion annually worldwide comprising visual equipment, audio equipment , and games consoles . It was truly global with Asia Pacific having 35% market share, Europe having 31.5%, the US having 23%, and the rest of the world having the rest. Major players in this industry are household names like Sony, Samsung, Philips, Sanyo, and Sharp. Samsung Electronics is part of Samsung . In 2003, combined revenues for Samsung Electronics were $ 55   billion. Samsung Electronics UK
