85-452: A Google Account is a user account that is required for access, authentication and authorization to certain online Google services. It is also often used as single sign-on for third party services. A Google Account is required for Gmail , Google Hangouts , Google Meet and Blogger . Some Google products do not require an account, including Google Search , YouTube , Google Books , Google Finance and Google Maps . However, an account

170-608: A fax or uploading some requested document) may require human interaction and may take some "days or a couple of weeks" to be accomplished. On May 17, 2023, Google announced that, starting in December 2023, it may delete inactive accounts that had not been used or signed into for at least two years. The company clarified to Rolling Stone that inactive accounts with YouTube content won't be deleted after many people feared that YouTube's old music archives, and deceased users whose accounts were popular, could be lost. Gmail Gmail

255-593: A search -oriented interface and supports a "conversation view" similar to an Internet forum . The service is notable among website developers for its early adoption of Ajax . Google's mail servers automatically scan emails for multiple purposes, including to filter spam and malware and, prior to June 2017, to add context-sensitive advertisements next to emails. This advertising practice has been significantly criticized by privacy advocates with concerns over unlimited data retention , ease of monitoring by third parties, users of other email providers not having agreed to

340-409: A "fax profile" subset of JBIG (ITU-T T.85). JBIG-compressed pages result in 20% to 50% faster transmission than MMR-compressed pages, and up to 30 times faster transmission if the page includes halftone images. JBIG performs adaptive compression , that is, both the encoder and decoder collect statistical information about the transmitted image from the pixels transmitted so far, in order to predict

425-600: A government has attempted to compromise an account, a notice will be displayed that reads "Warning: We believe state-sponsored attackers may be trying to compromise your account or computer." The tool called 'My Activity' launched in 2016 - which supersedes Google Search history and Google Web History — enables users to see and delete data tracked by Google through the Google account. The tool shows which websites were visited using Chrome while logged in, devices used, apps used, Google products interacted with, etc. All information

510-421: A greater number of lines to be coded by MR than in T.4. This is because T.6 makes the assumption that the transmission is over a circuit with a low number of line errors, such as digital ISDN . In this case, the number of lines for which the differences are encoded is not limited. In 1999, ITU-T recommendation T.30 added JBIG (ITU-T T.82) as another lossless bi-level compression algorithm, or more precisely

595-640: A pioneer in mechanical image scanning and transmission. The 1888 invention of the telautograph by Elisha Gray marked a further development in fax technology, allowing users to send signatures over long distances, thus allowing the verification of identification or ownership over long distances. On May 19, 1924, scientists of the AT&;T Corporation "by a new process of transmitting pictures by electricity" sent 15 photographs by telephone from Cleveland to New York City, such photos being suitable for newspaper reproduction. Previously, photographs had been sent over

680-471: A precaution, thermal fax paper is typically not accepted in archives or as documentary evidence in some courts of law unless photocopied. This is because the image-forming coating is eradicable and brittle, and it tends to detach from the medium after a long time in storage. A CNG tone is an 1100 Hz tone transmitted by a fax machine when it calls another fax machine. Fax tones can cause complications when implementing fax over IP . One popular alternative

765-514: A private Google account without a public-facing profile, starting in July 2015. In May 2013, Google announced the integration between Google Wallet and Gmail, which would allow Gmail users to send money as email attachments. Although the sender must use a Gmail account, the recipient does not need to be using a Gmail address. The feature has no transaction fees, but there are limits to the amount of money that can be sent. Initially only available on

850-460: A redesign of its interface that "simplified" the look of Gmail into a more minimalist design to provide a more consistent look throughout its products and services as part of an overall Google design change. Majorly redesigned elements included a streamlined conversation view, configurable density of information, new higher-quality themes, a resizable navigation bar with always-visible labels and contacts, and better search. Users were able to preview

935-585: A rolling basis. Gmail's "basic HTML" version works on almost all browsers. This version of Gmail has been discontinued from January 2024. In August 2011, Google introduced Gmail Offline, an HTML5 -powered app for providing access to the service while offline. Gmail Offline runs on the Google Chrome browser and can be downloaded from the Chrome Web Store . In addition to the native apps on iOS and Android, users can access Gmail through

1020-591: A single character. (JBIG implements a similar technique called "typical prediction", if header flag TPBON is set to 1.) Group 3 fax machines transfer one or a few printed or handwritten pages per minute in black-and-white (bitonal) at a resolution of 204×98 (normal) or 204×196 (fine) dots per square inch. The transfer rate is 14.4 kbit/s or higher for modems and some fax machines, but fax machines support speeds beginning with 2400 bit/s and typically operate at 9600 bit/s. The transferred image formats are called ITU-T (formerly CCITT) fax group 3 or 4. Group 3 faxes have

1105-676: A single page, an approach that was later copied by its competitors. Gmail's user interface designer, Kevin Fox , intended users to feel as if they were always on one page and just changing things on that page, rather than having to navigate to other places. Gmail's interface also makes use of 'labels' (tags) – that replace the conventional folders and provide a more flexible method of organizing emails; filters for automatically organizing, deleting or forwarding incoming emails to other addresses; and importance markers for automatically marking messages as 'important'. In November 2011, Google began rolling out

1190-619: A storage capacity of one gigabyte per user, which was significantly higher than its competitors offered at the time. Today, the service comes with 15 gigabytes of storage for free for individual users, which is divided among other Google services, such as Google Drive, and Google Photos. Users in need of more storage can purchase Google One to increase this 15 GB limit across most Google services. Users can receive emails up to 50 megabytes in size, including attachments, and can send emails up to 25 megabytes. Gmail supports integration with Google Drive , allowing for larger attachments. Gmail has

1275-541: A telefax machine. The Pantelegraph was invented by the Italian physicist Giovanni Caselli . He introduced the first commercial telefax service between Paris and Lyon in 1865, some 11 years before the invention of the telephone . In 1880, English inventor Shelford Bidwell constructed the scanning phototelegraph that was the first telefax machine to scan any two-dimensional original, not requiring manual plotting or drawing. An account of Henry Sutton's "telephane"

1360-466: A user's profiles on various social-networking and image-hosting sites, as well as user blogs . Third-party service providers may implement service authentication for Google Account holders via the Google Account mechanism. While creating a Google account, users are asked to provide a recovery email address to allow them to reset their password if they have forgotten it, or if their account

1445-412: Is designed to work with VoIP services and often supported by analog telephone adapters used by legacy fax machines that need to connect through a VoIP service. Scanned documents are limited to the amount of time the user takes to load the document in a scanner and for the device to process a digital file. The resolution can vary from as little as 150 DPI to 9600 DPI or more. This type of faxing

1530-454: Is either generated by an application (" Google Authenticator " or other similar apps) or received from Google as an SMS text message, a voice message, or an email to another account. Trusted devices can be "marked" to skip this 2-step log-on authentication. When this feature is switched on, software that cannot provide the validation code (e.g. IMAP and POP3 clients) must use a unique 16-character alphanumeric password generated by Google instead of

1615-494: Is for backup purposes, in case the first is lost. The Advanced Protection Program includes further security measures to protect the user's account, such as restrictions on which applications the user can grant access to their account, and a more thorough identity verification process for regaining access to the account if the password is forgotten. On June 5, 2012, a new security feature was introduced to protect users from state-sponsored attacks. Whenever Google analysis indicate that

1700-570: Is hacked. In some countries, such as the United States, the United Kingdom and India, Google may also require one-time use of a mobile phone number to send an account validation code by SMS text messaging or voice message when creating a new account. Google also offers a two-step verification option—for additional security against hacking—that requests a validation code each time the user logs into their Google account. The code

1785-454: Is laid out in a timeline-like layout. Users can choose to entirely disable tracking, or remove certain activities which they do not want to be tracked. Google may block an account for various reasons, such as "unusual activity" or entering an age "not old enough" to own a Google account. Reactivation is possible using web-forms, providing proof of identity through valid photos ID, or a credit card payment of US$ 0.30. Other methods (such as sending

1870-587: Is needed for uploading videos to YouTube and for making edits in Google Maps. YouTube and Blogger maintain separate accounts for users who registered with the services before the Google acquisition. However, effective April 2011 YouTube users are required to link to a separate Google Account if they wish to continue to log into that service. Google Account users may create a publicly accessible Google profile, to configure their presentation on Google products to other Google users. A Google profile can be linked to

1955-413: Is not related to the e-mail–to–fax service that still uses fax modems at least one way. Computer modems are often designated by a particular fax class, which indicates how much processing is offloaded from the computer's CPU to the fax modem. Several different telephone-line modulation techniques are used by fax machines. They are negotiated during the fax- modem handshake , and the fax devices will use

2040-430: Is preferable to use depends on factors such as hardware, software, modem firmware, and expected use. Fax machines from the 1970s to the 1990s often used direct thermal printers with rolls of thermal paper as their printing technology, but since the mid-1990s there has been a transition towards plain-paper faxes: thermal transfer printers , inkjet printers and laser printers . One of the advantages of inkjet printing

2125-457: Is still used by amateur radio operators. In 1964, Xerox Corporation introduced (and patented) what many consider to be the first commercialized version of the modern fax machine, under the name (LDX) or Long Distance Xerography. This model was superseded two years later with a unit that would set the standard for fax machines for years to come. Up until this point facsimile machines were very expensive and hard to operate. In 1966, Xerox released

2210-407: Is that inkjets can affordably print in color ; therefore, many of the inkjet-based fax machines claim to have color fax capability. There is a standard called ITU-T30e (formally ITU-T Recommendation T.30 Annex E ) for faxing in color; however, it is not widely supported, so many of the color fax machines can only fax in color to machines from the same manufacturer. Stroke speed in facsimile systems

2295-479: Is the email service provided by Google . As of 2019, it had 1.5 billion active users worldwide, making it the largest email service in the world. It also provides a webmail interface, accessible through a web browser , and is also accessible through the official mobile application . Google also supports the use of third-party email clients via the POP and IMAP protocols. At its launch in 2004, Gmail provided

2380-401: Is the rate at which a fixed line perpendicular to the direction of scanning is crossed in one direction by a scanning or recording spot . Stroke speed is usually expressed as a number of strokes per minute. When the fax system scans in both directions, the stroke speed is twice this number. In most conventional 20th century mechanical systems, the stroke speed is equivalent to drum speed. As

2465-468: Is to prevent errors propagating throughout the whole fax, as the standard does not provide for error correction. This is an optional facility, and some fax machines do not use MR in order to minimise the amount of computation required by the machine. The limited number of lines is 2 for "Standard"-resolution faxes, and 4 for "Fine"-resolution faxes. The ITU-T T.6 recommendation adds a further compression type of Modified Modified READ (MMR), which simply allows

2550-402: Is to subscribe to an Internet fax service, allowing users to send and receive faxes from their personal computers using an existing email account . No software, fax server or fax machine is needed. Faxes are received as attached TIFF or PDF files, or in proprietary formats that require the use of the service provider's software. Faxes can be sent or retrieved from anywhere at any time that

2635-504: The suffix .g3 and the MIME type image/g3fax . The most basic fax mode transfers in black and white only. The original page is scanned in a resolution of 1728 pixels /line and 1145 lines/page (for A4 ). The resulting raw data is compressed using a modified Huffman code optimized for written text, achieving average compression factors of around 20. Typically a page needs 10 s for transmission, instead of about three minutes for

2720-568: The "Undo Send" option, often "graduate" from Gmail Labs to become a formal setting in Gmail. All Labs features are experimental and are subject to termination at any time. Gmail incorporates a search bar for searching emails. The search bar can also search contacts, files stored in Google Drive , events from Google Calendar , and Google Sites . In May 2012, Gmail improved the search functionality to include auto-complete predictions from

2805-617: The 1980s and 1990s. They have largely been rendered obsolete by Internet -based technologies such as email and the World Wide Web , but are still used in some medical administration and law enforcement settings. Scottish inventor Alexander Bain worked on chemical-mechanical fax-type devices and in 1846 Bain was able to reproduce graphic signs in laboratory experiments. He received British patent 9745 on May 27, 1843, for his "Electric Printing Telegraph". Frederick Bakewell made several improvements on Bain's design and demonstrated

2890-460: The Gmail app for the iOS platform, bringing the first complete visual overhaul in "nearly four years". The update added much more use of colors, sleeker transitions, and the addition of several "highly-requested" features, including Undo Send, faster search with instant results and spelling suggestions, and Swipe to Archive/Delete. In May 2017, Google updated Gmail on Android to feature protection from phishing attacks. Media outlets noticed that

2975-399: The Gmail team, but serving as a "completely different type of inbox", the service is made to help users deal with the challenges of an active email. Citing issues such as distractions, difficulty in finding important information buried in messages, and receiving more emails than ever, Inbox by Gmail has several important differences from Gmail, including bundles that automatically sort emails of

3060-521: The Magnafax Telecopiers, a smaller, 46 lb (21 kg) facsimile machine. This unit was far easier to operate and could be connected to any standard telephone line. This machine was capable of transmitting a letter-sized document in about six minutes. The first sub-minute, digital fax machine was developed by Dacom , which built on digital data compression technology originally developed at Lockheed for satellite communication. By

3145-599: The NHS, was engaged in a process of removing its fax machines in early 2019. This involved quite a lot of e-fax solutions because of the need to communicate with pharmacies and nursing homes which may not have access to the NHS email system and may need something in their paper records. In 2018 two-thirds of Canadian doctors reported that they primarily used fax machines to communicate with other doctors. Faxes are still seen as safer and more secure and electronic systems are often unable to communicate with each other. Hospitals are

3230-403: The T.85 "fax profile": A proprietary compression scheme employed on Panasonic fax machines is Matsushita Whiteline Skip (MWS). It can be overlaid on the other compression schemes, but is operative only when two Panasonic machines are communicating with one another. This system detects the blank scanned areas between lines of text, and then compresses several blank scan lines into the data space of

3315-422: The ability to manually enable secure mode, with a toggle in the settings menu. In 2007, Google fixed a cross-site scripting security issue that could let attackers collect information from Gmail contact lists. In January 2010, Google began rolling out HTTPS as the default for all users. In June 2012, a new security feature was introduced to protect users from state-sponsored attacks. A banner will appear at

3400-432: The advantage of reducing costs by eliminating unnecessary printouts and reducing the number of inbound analog phone lines needed by an office. The once ubiquitous fax machine has also begun to disappear from the small office and home office environments. Remotely hosted fax-server services are widely available from VoIP and e-mail providers allowing users to send and receive faxes using their existing e-mail accounts without

3485-597: The dashboard of Western Union 's "Telecar" telegram delivery vehicles. In the 1960s, the United States Army transmitted the first photograph via satellite facsimile to Puerto Rico from the Deal Test Site using the Courier satellite . Radio fax is still in limited use today for transmitting weather charts and information to ships at sea. The closely related technology of slow-scan television

3570-542: The digital revolution has largely bypassed it. In June 2018 the Labour Party said that the NHS had at least 11,620 fax machines in operation and in December the Department of Health and Social Care said that no more fax machines could be bought from 2019 and that the existing ones must be replaced by secure email by March 31, 2020. Leeds Teaching Hospitals NHS Trust , generally viewed as digitally advanced in

3655-408: The end of the use of contextual Gmail content for advertising purposes, relying instead on data gathered from the use of its other services. On April 1, 2004, Gmail was launched with one gigabyte (GB) of storage space, a significantly higher amount than competitors offered at the time. The limit was doubled to two gigabytes of storage on April 1, 2005, the first anniversary of Gmail. Georges Harik,

3740-612: The entire update can be disabled, allowing users to return to the traditional inbox structure. In April 2018, Google introduced a new web UI for Gmail. The new redesign follows Google's Material Design , and changes in the user interface include the use of Google's Product Sans font. Other updates include a Confidential mode , which allows the sender to set an expiration date for a sensitive message or to revoke it entirely, integrated rights management and two-factor authentication . On 16 November 2020, Google announced new settings for smart features and personalization in Gmail. Under

3825-403: The fax machines to transfer the image. The two methods defined in T.4 are: An additional method is specified in T.6: Later, other compression techniques were added as options to ITU-T recommendation T.30, such as the more efficient JBIG (T.82, T.85) for bi-level content, and JPEG (T.81), T.43, MRC (T.44), and T.45 for grayscale, palette, and colour content. Fax machines can negotiate at

3910-483: The first photo picture reproduced by transoceanic radio facsimile. Commercial use of Ranger's product began two years later. Also in 1924, Herbert E. Ives of AT&T transmitted and reconstructed the first color facsimile, a natural-color photograph of silent film star Rudolph Valentino in period costume, using red, green and blue color separations. Beginning in the late 1930s, the Finch Facsimile system

3995-434: The first scanned line using MH. The next line is compared to the first, the differences determined, and then the differences are encoded and transmitted. This is effective, as most lines differ little from their predecessor. This is not continued to the end of the fax transmission, but only for a limited number of lines until the process is reset, and a new "first line" encoded with MH is produced. This limited number of lines

4080-508: The highest data rate that both fax devices support, usually a minimum of 14.4 kbit/s for Group 3 fax. "Super Group 3" faxes use V.34bis modulation that allows a data rate of up to 33.6 kbit/s. As well as specifying the resolution (and allowable physical size) of the image being faxed, the ITU-T ;T.4 recommendation specifies two compression methods for decreasing the amount of data that needs to be transmitted between

4165-504: The language of your keyboard." In October 2013, Google added handwriting input support to Gmail. In August 2014, Gmail became the first major email provider to let users send and receive emails from addresses with accent marks and letters from outside the Latin alphabet . The modern AJAX version is officially supported in the current and previous major releases of Google Chrome , Firefox , Microsoft Edge and Safari web browsers on

4250-446: The late 1970s, many companies around the world (especially Japanese firms) had entered the fax market. Very shortly after this, a new wave of more compact, faster and efficient fax machines would hit the market. Xerox continued to refine the fax machine for years after their ground-breaking first machine. In later years it would be combined with copier equipment to create the hybrid machines we have today that copy, scan and fax. Some of

4335-491: The leading users for fax machines in the United States where some doctors prefer fax machines over emails, often due to concerns about accidentally violating HIPAA . There are several indicators of fax capabilities: group, class, data transmission rate, and conformance with ITU-T (formerly CCITT ) recommendations. Since the 1968 Carterfone decision , most fax machines have been designed to connect to standard PSTN lines and telephone numbers. Group 1 and 2 faxes are sent in

4420-525: The lesser known capabilities of the Xerox fax technologies included their Ethernet enabled Fax Services on their 8000 workstations in the early 1980s. Prior to the introduction of the ubiquitous fax machine, one of the first being the Exxon Qwip in the mid-1970s, facsimile machines worked by optical scanning of a document or drawing spinning on a drum. The reflected light, varying in intensity according to

4505-417: The light and dark areas of the document, was focused on a photocell so that the current in a circuit varied with the amount of light. This current was used to control a tone generator (a modulator ), the current determining the frequency of the tone produced. This audio tone was then transmitted using an acoustic coupler (a speaker, in this case) attached to the microphone of a common telephone handset . At

4590-452: The more probable pixel is then encountered. The ITU-T T.85 "fax profile" constrains some optional features of the full JBIG standard, such that codecs do not have to keep data about more than the last three pixel rows of an image in memory at any time. This allows the streaming of "endless" images, where the height of the image may not be known until the last row is transmitted. ITU-T T.30 allows fax machines to negotiate one of two options of

4675-448: The need for any hardware or dedicated fax lines. Personal computers have also long been able to handle incoming and outgoing faxes using analog modems or ISDN , eliminating the need for a stand-alone fax machine. These solutions are often ideally suited for users who only very occasionally need to use fax services. In July 2017 the United Kingdom's National Health Service was said to be the world's largest purchaser of fax machines because

4760-458: The new interface design for months prior to the official release, as well as revert to the old interface, until March 2012, when Google discontinued the ability to revert and completed the transition to the new design for all users. In May 2013, Google updated the Gmail inbox with tabs which allow the application to categorize the user's emails. The five tabs are: Primary, Social, Promotions, Updates, and Forums. In addition to customization options,

4845-476: The new protection was announced amid a widespread phishing attack on a combination of Gmail and Google's Docs document service that occurred on the same day. Later in May, Google announced the addition of "Smart Reply" to Gmail on Android and iOS. "Smart Reply", a feature originally launched for Google's Inbox by Gmail service, scans a message for information and uses machine intelligence to offer three responses

4930-455: The new settings users were given control of their data in Gmail, Chat, and Meet, offering smart features like Smart Compose and Smart Reply. On 6 April 2021, Google rolled out Google Chat and Room (early access) feature to all Gmail users. On 28 July 2022, Google rolled out Material You to all Gmail users. Gmail's spam filtering features a community-driven system: when any user marks an email as spam , this provides information to help

5015-633: The overall merge of storage across Gmail, Google Drive, and Google+ Photos, allowing users 15 gigabytes of included storage among three services. On August 15, 2018, Google launched Google One , a service where users can pay for additional storage, shared among Gmail, Google Drive and Google Photos , through a monthly subscription plan. As of 2021 , storage of up to 15 gigabytes is included, and paid plans are available for up to 2 terabytes for personal use. There are also storage limits to individual Gmail messages. Initially, one message, including all attachments, could not be larger than 25 megabytes . This

5100-587: The policy upon sending emails to Gmail addresses, and the potential for Google to change its policies to further decrease privacy by combining information with other Google data usage. The company has been the subject of lawsuits concerning the issues. Google has stated that email users must "necessarily expect" their emails to be subject to automated processing and claims that the service refrains from displaying ads next to potentially sensitive messages, such as those mentioning race, religion, sexual orientation, health, or financial statements. In June 2017, Google announced

5185-419: The probability for each next pixel being either black or white. For each new pixel, JBIG looks at ten nearby, previously transmitted pixels. It counts, how often in the past the next pixel has been black or white in the same neighborhood, and estimates from that the probability distribution of the next pixel. This is fed into an arithmetic coder , which adds only a small fraction of a bit to the output sequence if

5270-424: The product management director for Gmail, stated that Google would "keep giving people more space forever." In October 2007, Gmail increased storage to 4 gigabytes, after recent changes from competitors Yahoo and Microsoft. On April 24, 2012, Google announced the increase of storage included in Gmail from 7.5 to 10 gigabytes ("and counting") as part of the launch of Google Drive . On May 13, 2013, Google announced

5355-618: The radio using this process. The Western Union "Deskfax" fax machine, announced in 1948, was a compact machine that fit comfortably on a desktop, using special spark printer paper. As a designer for the Radio Corporation of America (RCA), in 1924, Richard H. Ranger invented the wireless photoradiogram, or transoceanic radio facsimile , the forerunner of today's "fax" machines. A photograph of President Calvin Coolidge sent from New York to London on November 29, 1924, became

5440-566: The receiving end, a handset's speaker was attached to an acoustic coupler (a microphone), and a demodulator converted the varying tone into a variable current that controlled the mechanical movement of a pen or pencil to reproduce the image on a blank sheet of paper on an identical drum rotating at the same rate. In 1985, Hank Magnuski , founder of GammaLink , produced the first computer fax board, called GammaFax . Such boards could provide voice telephony via Analog Expansion Bus . Although businesses usually maintain some kind of fax capability,

5525-454: The recipient also has Google Trips, the information will be automatically available in their apps as well. Google has supported the secure HTTPS since the day it launched. In the beginning, it was only default on the login page, a reason that Google engineer Ariel Rideout stated was because HTTPS made "your mail slower". However, users could manually switch to secure HTTPS mode inside the inbox after logging in. In July 2008, Google simplified

5610-426: The same manner as a frame of analog television , with each scanned line transmitted as a continuous analog signal. Horizontal resolution depended upon the quality of the scanner, transmission line, and the printer. Analog fax machines are obsolete and no longer manufactured. ITU-T Recommendations T.2 and T.3 were withdrawn as obsolete in July 1996. A major breakthrough in the development of the modern facsimile system

5695-427: The same topic together, highlights that surface key information from messages, and reminders, assists, and snooze, that help the user in handling incoming emails at appropriate times. Inbox by Gmail became publicly available in May 2015. In September 2018, Google announced it would end the service at the end of March 2019, most of its key features having been incorporated into the standard Gmail service. The service

5780-557: The same uncompressed raw data of 1728×1145 bits at a speed of 9600 bit/s. The compression method uses a Huffman codebook for run lengths of black and white runs in a single scanned line, and it can also use the fact that two adjacent scanlines are usually quite similar, saving bandwidth by encoding only the differences. Fax classes denote the way fax programs interact with fax hardware. Available classes include Class 1, Class 2, Class 2.0 and 2.1, and Intel CAS. Many modems support at least class 1 and often either Class 2 or Class 2.0. Which

5865-815: The slightly re-sized content of the sent fax in the electronic confirmation-slip, in A4 paper size. Use of fax machines for reporting cases during the COVID-19 pandemic has been criticised in Japan for introducing data errors and delays in reporting, slowing response efforts to contain the spread of infections and hindering the transition to remote work . In many corporate environments, freestanding fax machines have been replaced by fax servers and other computerized systems capable of receiving and storing incoming faxes electronically, and then routing them to users on paper or via an email (which may be secured). Such systems have

5950-522: The start of the T.30 session to use the best technique implemented on both sides. Modified Huffman (MH), specified in T.4 as the one-dimensional coding scheme, is a codebook-based run-length encoding scheme optimised to efficiently compress whitespace. As most faxes consist mostly of white space, this minimises the transmission time of most faxes. Each line scanned is compressed independently of its predecessor and successor. Modified READ, specified as an optional two-dimensional coding scheme in T.4, encodes

6035-578: The system identify similar future messages for all Gmail users. In the April 2018 update, the spam filtering banners got a redesign, with bigger and bolder lettering. The Gmail Labs feature, introduced on June 5, 2008, allows users to test new or experimental features of Gmail. Users can enable or disable Labs features selectively and provide feedback about each of them. This allows Gmail engineers to obtain user input about new features to improve them and also to assess their popularity. Popular features, like

6120-575: The technology has faced increasing competition from Internet -based alternatives. In some countries, because electronic signatures on contracts are not yet recognized by law , while faxed contracts with copies of signatures are, fax machines enjoy continuing support in business. In Japan , faxes are still used extensively as of September 2020 for cultural and graphemic reasons. They are available for sending to both domestic and international recipients from over 81% of all convenience stores nationwide. Convenience-store fax machines commonly print

6205-435: The top of the page that warns users of an unauthorized account compromise. In March 2014, Google announced that an encrypted HTTPS connection would be used for the sending and receiving of all Gmail emails, and "every single email message you send or receive —100% of them —is encrypted while moving internally" through the company's systems. Fax Initially a niche product, fax machines became ubiquitous in offices in

6290-694: The user can optionally edit and send. The feature is limited to the English language at launch, with additional support for Spanish, followed by other languages arriving later. Inbox by Gmail, another app from the Gmail team, was also available for iOS and Android devices. It was discontinued in April 2019. Third-party programs can be used to access Gmail, using the POP or IMAP protocols. In 2019, Google rolled out dark mode for its mobile apps in Android and iOS . In October 2014, Google introduced Inbox by Gmail on an invitation-only basis. Developed by

6375-1220: The user's emails. Gmail's search functionality does not support searching for word fragments (also known as 'substring search' or partial word search). Workarounds exist. As of March 2015 , the Gmail interface supports 72 languages, including: Arabic , Basque , Bulgarian , Catalan , Chinese (simplified) , Chinese (traditional) , Croatian , Czech , Danish , Dutch , English (UK) , English (US) , Estonian , Finnish , French , German , Greek , Gujarati , Hebrew , Hindi , Hungarian , Icelandic , Indonesian , Italian , Japanese , Kannada , Korean , Latvian , Lithuanian , Malay , Malayalam , Marathi , Norwegian (Bokmål) , Odia , Persian , Polish , Punjabi , Portuguese (Brazil) , Portuguese (Portugal) , Romanian , Russian , Serbian , Sinhala , Slovak , Slovenian , Spanish , Swedish , Tagalog (Filipino) , Tamil , Telugu , Thai , Turkish , Ukrainian , Urdu , Vietnamese , Welsh and Zulu . In October 2012, Google added over 100 virtual keyboards, transliterations , and input method editors to Gmail, enabling users different types of input styles for different languages in an effort to help users write in languages that are not "limited by

6460-500: The user's normal password. Users who seek an even higher level of security protection, including users whose accounts could be attractive targets for hackers, such as celebrities, politicians, journalists, political activists and wealthy individuals, can opt-in to Google's Advanced Protection Program. This program requires the user to purchase two U2F USB keys — not for data storage, but for identity verification. The U2F keys are used to provide two-step verification during login. One

6545-471: The web browser on a mobile device. Gmail has native applications for iOS devices (including iPhone , iPad , and iPod Touch ) and for Android devices. In November 2014, Google introduced functionality in the Gmail Android app that enabled sending and receiving emails from non-Gmail addresses (such as Yahoo! Mail and Outlook.com ) through POP or IMAP. In November 2016, Google redesigned

6630-846: The web, the feature was expanded to the Android app in March 2017, for people living in the United States. In September 2016, Google released Google Trips , an app that, based on information from a user's Gmail messages, automatically generates travel cards. A travel card contains itinerary details, such as plane tickets and car rentals, and recommends activities, food and drinks, and attractions based on location, time, and interests. The app also has offline functionality. In April 2017, Google Trips received an update adding several significant features. The app now also scans Gmail for bus and train tickets, and allows users to manually input trip reservations. Users can send trip details to other users' email, and if

6715-433: Was changed in March 2017 to allow receiving an email of up to 50 megabytes, while the limit for sending an email stayed at 25 megabytes. In order to send larger files, users can insert files from Google Drive into the message. The Gmail user interface initially differed from other web-mail systems with its focus on search and conversation threading of emails, grouping several messages between two or more people onto

6800-526: Was discontinued in October 2011, replaced with new functionality in Google+ , Google's then-new social networking platform. Gmail was integrated with Google+ in December 2011, as part of an effort to have all Google information across one Google account, with a centralized Google+ user profile. Backlash from the move caused Google to step back and remove the requirement of a Google+ user account, keeping only

6885-706: Was discontinued on April 2, 2019. In August 2010, Google released a plugin that provides integrated telephone service within Gmail's Google Chat interface. The feature initially lacked an official name, with Google referring to it as both "Google Voice in Gmail chat" and "Call Phones in Gmail". The service logged over one million calls in 24 hours. In March 2014, Google Voice was discontinued, and replaced with functionality from Google Hangouts , another communication platform from Google. On February 9, 2010, Google commenced its new social networking tool, Google Buzz , which integrated with Gmail, allowing users to share links and media, as well as status updates. Google Buzz

6970-645: Was published in 1896. Around 1900, German physicist Arthur Korn invented the Bildtelegraph , widespread in continental Europe especially following a widely noticed transmission of a wanted-person photograph from Paris to London in 1908, used until the wider distribution of the radiofax. Its main competitors were the Bélinographe by Édouard Belin first, then since the 1930s the Hellschreiber , invented in 1929 by German inventor Rudolf Hell ,

7055-802: Was the result of digital technology, where the analog signal from scanners was digitized and then compressed, resulting in the ability to transmit high rates of data across standard phone lines. The first digital fax machine was the Dacom Rapidfax first sold in late 1960s, which incorporated digital data compression technology developed by Lockheed for transmission of images from satellites. Group 3 and 4 faxes are digital formats and take advantage of digital compression methods to greatly reduce transmission times. Fax Over IP ( FoIP ) can transmit and receive pre-digitized documents at near-realtime speeds using ITU-T recommendation T.38 to send digitised images over an IP network using JPEG compression. T.38

7140-469: Was too small. After more than ten years of repeated attempts by Finch and others to establish such a service as a viable business, the public, apparently quite content with its cheaper and much more substantial home-delivered daily newspapers, and with conventional spoken radio bulletins to provide any "hot" news, still showed only a passing curiosity about the new medium. By the late 1940s, radiofax receivers were sufficiently miniaturized to be fitted beneath

7225-401: Was used to transmit a "radio newspaper" to private homes via commercial AM radio stations and ordinary radio receivers equipped with Finch's printer, which used thermal paper. Sensing a new and potentially golden opportunity, competitors soon entered the field, but the printer and special paper were expensive luxuries, AM radio transmission was very slow and vulnerable to static, and the newspaper
