42-596: PC World (stylized as PCWorld ) is a global computer magazine published monthly by IDG . Since 2013, it has been an online-only publication. It offers advice on various aspects of PCs and related items, the Internet, and other personal technology products and services. In each publication, PC World reviews and tests hardware and software products from a variety of manufacturers, as well as other technology related devices such as still and video cameras , audio devices and televisions. The current editor of PC World

84-485: A keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. (See "Personal Computer: Computers at Companies" reference below) . A "microcomputer" used as an embedded control system may have no human-readable input and output devices. "Personal computer" may be used generically or may denote an IBM PC compatible machine. The abbreviation "micro"

126-492: A printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers , were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with

168-870: A proof of concept to demonstrate what such a simple device could do. As microprocessors and semiconductor memory became less expensive, microcomputers grew cheaper and easier to use. All these improvements in cost and usability resulted in an explosion in their popularity during the late 1970s and early 1980s. A large number of computer makers packaged microcomputers for use in small business applications. By 1979, many companies such as Cromemco , Processor Technology , IMSAI , North Star Computers , Southwest Technical Products Corporation , Ohio Scientific , Altos Computer Systems , Morrow Designs and others produced systems designed for resourceful end users or consulting firms to deliver business systems such as accounting, database management and word processing to small businesses. This allowed businesses unable to afford leasing of

210-595: A computer based on a microprocessor – the Intel 8008 8-bit microprocessor. This Micral-N was marketed in early 1973 as a "Micro-ordinateur" or microcomputer , mainly for scientific and process-control applications. About a hundred Micral-N were installed in the next two years, followed by a new version based on the Intel 8080. Meanwhile, another French team developed the Alvan, a small computer for office automation which found clients in banks and other sectors. The first version

252-463: A computer had to be big in size to be powerful, and thus decided to market them as calculators. Additionally, at that time, people were more likely to buy calculators than computers, and, purchasing agents also preferred the term "calculator" because purchasing a "computer" required additional layers of purchasing authority approvals. The Datapoint 2200 , made by CTC in 1970, was also comparable to microcomputers. While it contains no microprocessor,

294-422: A disk operating system included in a series of programmable read-only memory chips (PROMs); 8 Kilobytes of RAM; IBM's Basic Assembly Language (BAL); a hard drive; a color display; a printer output; a 150 bit/s serial interface for connecting to a mainframe; and even the world's first microcomputer front panel. In early 1973, Sord Computer Corporation (now Toshiba Personal Computer System Corporation ) completed

336-419: A minicomputer or time-sharing service the opportunity to automate business functions, without (usually) hiring a full-time staff to operate the computers. A representative system of this era would have used an S100 bus , an 8-bit processor such as an Intel 8080 or Zilog Z80 , and either CP/M or MP/M operating system. The increasing availability and power of desktop computers for personal use attracted

378-450: A record of 1,000,453. At the time, it was the first and only computing magazine with a monthly release schedule to hit that mark. In April 2005, the show Digital Duo was slightly rebranded and relaunched as PC World's Digital Duo , and ran for an additional 26 episodes. As of 2006, PC World ' s audited rate base of 750,000 made it the largest circulation computing magazine in the world. On July 10, 2013, owner IDG announced that

420-557: A time, although they can often be modified with software or hardware to concurrently serve more than one user. Microcomputers fit well on or under desks or tables, so that they are within easy access of users. Bigger computers like minicomputers , mainframes , and supercomputers take up large cabinets or even dedicated rooms. A microcomputer comes equipped with at least one type of data storage, usually RAM . Although some microcomputers (particularly early 8-bit home micros) perform tasks using RAM alone, some form of secondary storage

462-642: Is IDG Consumer & SMB, and it is headquartered in San Francisco. Some of the non-English PC World websites now redirect to other IDG sites; for example, PCWorld.dk (Denmark) is now Computerworld .dk The publication was announced at the COMDEX trade show in November 1982, and first appeared on newsstands in March 1983. The magazine was founded by David Bunnell and Cheryl Woodard, and its first editor

504-531: Is Jon Phillips, formerly of Wired . In August 2012, he replaced Steve Fox, who had been editorial director since the December 2008 issue of the magazine. Fox replaced the magazine's veteran editor Harry McCracken , who resigned that spring, after some rocky times, including quitting and being rehired over editorial control issues in 2007. PC World is published under other names such as PC Advisor and PC Welt in some countries. PC World ' s company name

546-806: Is normally desirable. In the early days of home micros, this was often a data cassette deck (in many cases as an external unit). Later, secondary storage (particularly in the form of floppy disk and hard disk drives) were built into the microcomputer case. Although they did not contain any microprocessors, but were built around transistor-transistor logic (TTL), Hewlett-Packard calculators as far back as 1968 had various levels of programmability comparable to microcomputers. The HP 9100B (1968) had rudimentary conditional (if) statements, statement line numbers, jump statements ( go to ), registers that could be used as variables, and primitive subroutines. The programming language resembled assembly language in many ways. Later models incrementally added more features, including

588-534: Is sometimes called the first generation of microcomputers. Many companies such as DEC , National Semiconductor , Texas Instruments offered their microcomputers for use in terminal control, peripheral device interface control and industrial machine control. There were also machines for engineering development and hobbyist personal use. In 1975, the Processor Technology SOL-20 was designed, which consisted of one board which included all

630-450: The BASIC programming language (HP 9830A in 1971). Some models had tape storage and small printers. However, displays were limited to one line at a time. The HP 9100A was referred to as a personal computer in an advertisement in a 1968 Science magazine, but that advertisement was quickly dropped. HP was reluctant to sell them as "computers" because the perception at that time was that

672-597: The Micral N. The same year the company filed their patents with the term "Micro-ordinateur", a literal equivalent of "Microcomputer", to designate a solid state machine designed with a microprocessor. In the US the earliest models such as the Altair 8800 were often sold as kits to be assembled by the user, and came with as little as 256 bytes of RAM , and no input/output devices other than indicator lights and switches, useful as

714-444: The hobbyist end of the then- microcomputer market, and used to contain type-in programs , but these have gone out of fashion. The first magazine devoted to this class of computers was Creative Computing . Byte was an influential technical journal that published until the 1990s. In 1983, an average of one new computer magazine appeared each week. By late that year more than 200 existed. Their numbers and size grew rapidly with

756-566: The instruction set of its custom TTL processor was the basis of the instruction set for the Intel 8008 , and for practical purposes the system behaves approximately as if it contains an 8008. This is because Intel was the contractor in charge of developing the Datapoint's CPU, but ultimately CTC rejected the 8008 design because it needed 20 support chips. Another early system, the Kenbak-1 ,

798-539: The "150 or so" industry magazines published articles without clearly identifying authors' affiliations and conflicts of interest . Around 1985, many magazines ended. However, as their number exceeded the amount of available advertising revenue despite revenue in the first half of the year five times that of the same period in 1982. Consumers typically bought computer magazines more for advertising than articles, which benefited already leading journals like BYTE and PC Magazine and hurt weaker ones. Also affecting magazines

840-549: The Altair itself was only a mild commercial success, it helped spark a huge industry. By 1977, the introduction of the second microcomputer generation as consumer goods , known as home computers , made them considerably easier to use than their predecessors because their predecessors' operation often demanded thorough familiarity with practical electronics. The ability to connect to a monitor (screen) or TV set allowed visual manipulation of text and numbers. The BASIC language, which

882-623: The IBM PC itself was widely imitated, as well as the term. The component parts were commonly available to producers and the BIOS was reverse engineered through cleanroom design techniques. IBM PC compatible "clones" became commonplace, and the terms "personal computer", and especially "PC", stuck with the general public, often specifically for a computer compatible with DOS (or nowadays Windows). Monitors, keyboards and other devices for input and output may be integrated or separate. Computer memory in

924-702: The SMP80/08, which used the Intel 8008 microprocessor. The SMP80/08, however, did not have a commercial release. After the first general-purpose microprocessor, the Intel 8080 , was announced in April 1974, Sord announced the SMP80/x, the first microcomputer to use the 8080, in May 1974. Virtually all early microcomputers were essentially boxes with lights and switches; one had to read and understand binary numbers and machine language to program and use them (the Datapoint 2200

966-439: The attention of more software developers. As the industry matured, the market for personal computers standardized around IBM PC compatibles running DOS , and later Windows . Modern desktop computers, video game consoles , laptops , tablet PCs , and many types of handheld devices , including mobile phones , pocket calculators , and industrial embedded systems , may all be considered examples of microcomputers according to

1008-520: The definition given above. By the early 2000s, everyday use of the expression "microcomputer" (and in particular "micro") declined significantly from its peak in the mid-1980s. The term is most commonly associated with the most popular 8-bit home computers (such as the Apple II , ZX Spectrum , Commodore 64 , BBC Micro , and TRS-80 ) and small-business CP/M -based microcomputers. In colloquial usage, "microcomputer" has been largely supplanted by

1050-501: The form of RAM , and at least one other less volatile, memory storage device are usually combined with the CPU on a system bus in one unit. Other devices that make up a complete microcomputer system include batteries, a power supply unit, a keyboard and various input/output devices used to convey information to and from a human operator ( printers , monitors , human interface devices ). Microcomputers are designed to serve only one user at

1092-507: The heyday of printed computer magazines was a period during the 1990s, in which a large number of computer manufacturers took out advertisements in computer magazines, so they became quite thick and could afford to carry quite a number of articles in each issue. Computer Shopper was a good example of this trend. Some printed computer magazines used to include covermount floppy disks , CDs , or other media as inserts; they typically contained software , demos , and electronic versions of

1134-412: The industry they covered, and BYTE and 80 Micro were among the three thickest magazines of any kind per issue. Compute! ' s editor in chief reported in the December 1983 issue that "all of our previous records are being broken: largest number of pages, largest-number of four-color advertising pages, largest number of printing pages, and the largest number of editorial pages". Computers were

1176-581: The industry". Computer Gaming World stated in 1988 that it was the only one of the 18 color magazines that covered computer games in 1983 to survive the crash. Compute! similarly stated that year that it was the only general-interest survivor of about 150 consumer-computing magazines published in 1983. Some computer magazines in the 1980s and 1990s were issued only on disk (or cassette tape, or CD-ROM) with no printed counterpart; such publications are collectively (though somewhat inaccurately) known as disk magazines and are listed separately . In some ways

1218-621: The magazine would cease its thirty-year print run. The issue of August 2013 was the last printed of the magazine PC World , future issues would be digital only. Based in San Francisco, PC World ' s original edition is published in the United States; however it is also available in other countries (51 in total), sometimes under a different name: In May 2007, McCracken resigned abruptly under controversial circumstances. According to sources quoted in Wired , McCracken quit abruptly because

1260-497: The minicomputer's CPU with one integrated microprocessor chip . In 1973, the French Institut National de la Recherche Agronomique (INRA) was looking for a computer able to measure agricultural hygrometry . To answer this request, a team of French engineers of the computer technology company R2E, led by its Head of Development, François Gernelle , created the first available microprocessor-based microcomputer,

1302-618: The new CEO of PC World , Colin Crawford, tried to kill an unfavorable story about Apple and Steve Jobs . Crawford responded, calling media reports of McCracken's resignation "inaccurate". CNET later reported that McCracken had told colleagues that IDG "was pressuring him to avoid stories that were critical of major advertisers." On May 9, Crawford was transferred to another department, and McCracken returned to PC World until his departure in 2008.

1344-710: The only industry with product-specific magazines, like 80 Micro , PC Magazine , and Macworld ; their editors vowed to impartially cover their computers whether or not doing so hurt their readers' and advertisers' market, while claiming that their rivals pandered to advertisers by only publishing positive news. BYTE, in March 1984, apologized for publishing articles by authors with promotional material for companies without describing them as such, and in April suggested that other magazines adopt its rules of conduct for writers, such as prohibiting employees from accepting gifts or discounts. InfoWorld stated in June that many of

1386-468: The parts of the computer system. The SOL-20 had built-in EPROM software which eliminated the need for rows of switches and lights. The MITS Altair just mentioned played an instrumental role in sparking significant hobbyist interest, which itself eventually led to the founding and success of many well-known personal computer hardware and software companies, such as Microsoft and Apple Computer . Although

1428-561: The print issue. However, with the rise in popularity of the Internet , many computer magazines went bankrupt or transitioned to an online-only existence. Exceptions include Wired , which is more of a technology magazine than a computer magazine. Microcomputer A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor . The computer also includes memory and input/output (I/O) circuitry together mounted on

1470-452: The term " personal computer " or "PC", which specifies a computer that has been designed to be used by one individual at a time, a term first coined in 1959. IBM first promoted the term "personal computer" to differentiate the IBM PC from CP/M -based microcomputers likewise targeted at the small-business market, and also IBM's own mainframes and minicomputers. However, following its release,

1512-992: Was Andrew Fluegelman . PC World ' s magazine and web site have won a number of awards from Folio, the American Society of Business Publication Editors, MIN, the Western Publications Association, and other organizations; it is also one of the few technology magazines to have been a finalist for a National Magazine Award . Many well known technology writers have contributed to PC World , including Steve Bass, Daniel Tynan , Christina Wood, John C. Dvorak , Stephen Manes , Lincoln Spector, Stewart Alsop , David Coursey, James A. Martin, and others. Editorial leadership has included Harry Miller, Richard Landry, Eric Knorr, Phil Lemmons, Cathryn Baskin, Kevin McKean, and Harry McCracken. In February 1999, PC World ' s number of paid subscriptions reached

1554-493: Was a striking exception, bearing a modern design based on a monitor, keyboard, and tape and disk drives). Of the early "box of switches"-type microcomputers, the MITS Altair 8800 (1975) was arguably the most famous. Most of these simple, early microcomputers were sold as electronic kits —bags full of loose components which the buyer had to solder together before the system could be used. The period from about 1971 to 1976

1596-535: Was based on LSI chips with an Intel 8008 as peripheral controller (keyboard, monitor and printer), before adopting the Zilog Z80 as main processor. In late 1972, a Sacramento State University team led by Bill Pentz built the Sac State 8008 computer, able to handle thousands of patients' medical records. The Sac State 8008 was designed with the Intel 8008. It had a full set of hardware and software components :

1638-546: Was common during the 1970s and 1980s, but has since fallen out of common usage. The term microcomputer came into popular use after the introduction of the minicomputer , although Isaac Asimov used the term in his short story " The Dying Night " as early as 1956 (published in The Magazine of Fantasy and Science Fiction in July that year). Most notably, the microcomputer replaced the many separate components that made up

1680-474: Was easier to learn and use than raw machine language, became a standard feature. These features were already common in minicomputers , with which many hobbyists and early produces were familiar. In 1979, the launch of the VisiCalc spreadsheet (initially for the Apple II ) first turned the microcomputer from a hobby for computer enthusiasts into a business tool. After the 1981 release by IBM of its IBM PC ,

1722-429: Was released in 1971. Like the Datapoint 2200, it used small-scale integrated transistor–transistor logic instead of a microprocessor. It was marketed as an educational and hobbyist tool, but it was not a commercial success; production ceased shortly after introduction. In late 1972, a French team headed by François Gernelle within a small company, Réalisations & Etudes Electroniques (R2E), developed and patented

1764-674: Was the computer industry's economic difficulties, including the video game crash of 1983 , which badly hurt the home-computer market. Dan Gutman , the founder of Computer Games , recalled in 1987 that "the computer games industry crashed and burned like a bad night of Flight Simulator —with my magazine on the runway". Antic 's advertising sales declined by 50% in 90 days, Compute! 's number of pages declined from 392 in December 1983 to 160 ten months later, and Compute! and Compute!'s Gazette 's publisher assured readers in an editorial that his company "is and continues to be quite successful ... even during these particularly difficult times in
