Chrome OS – Wikipedia

Linux-based operating system developed by Google
This article is about the function system. For the world wide web browser, see Google Chrome
Chrome OS ( sometimes styled as chromeOS ) is a proprietorship Linux -based operating system designed by Google. It is derived from the open-source Chromium OS and uses the Google Chrome world wide web browser as its principal drug user interface.

Google announced the project, then based on Ubuntu, [ 7 ] in July 2009, conceiving it as an operating system in which both applications and drug user data reside in the cloud : hence Chrome OS chiefly runs web applications. [ 8 ] Source code and a public demonstration came that November. The first Chrome OS laptop, known as a Chromebook, arrived in May 2011. initial Chromebook shipments from Samsung and Acer occurred in July 2011. Chrome OS has an integrated media player and file director. It supports Progressive Web Apps and Chrome Apps ; these resemble native applications, a good as distant entree to the desktop. As more Chrome OS machines have entered the market, the operating system is now rarely evaluated apart from the hardware that runs it. [ 9 ] Android applications started to become available for the operating system in 2014, and in 2016, access to Android apps in Google Play ‘s entirety was introduced on supported Chrome OS devices. confirm for a Linux terminal and applications, known as Project Crostini, [ 10 ] was released to the static channel in 2018 with Chrome OS 69. This was made potential via a lightweight Linux kernel that runs containers inside a virtual machine .

history [edit ]

Google announced Chrome OS on July 7, 2009, [ 1 ] describing it as an operate system in which both applications and drug user data occupy in the cloud. To ascertain marketing requirements, the caller relied on cozy metrics, including monitoring the custom patterns of some 200 Chrome OS machines used by Google employees. Developers besides noted their own usage patterns. Matthew Papakipos, the early [ 11 ] technology director for the Chrome OS project, put three machines in his sign of the zodiac and found himself logging in for abbreviated sessions : to make a single search question or send a short e-mail. [ 12 ] The initial builds of Chrome OS were based on Ubuntu, and its developer, Canonical, was an engineer partner with Google on the project. In 2010, Chrome OS moved to Gentoo Linux as its base to simplify its build action and support a variety show of platforms. erstwhile in 2013, Google switched Chrome OS to its own relish of Linux. [ 7 ] Chrome OS was initially intended for secondary devices like netbooks, not as a drug user ‘s primary personal computer. [ 13 ] [ 14 ] While Chrome OS supports hard disk drives, Google has requested that its hardware partners use solid-state drives “ for performance and dependability reasons ” [ 15 ] equally well as the lower capacity requirements built-in in an operate on arrangement that accesses applications and most drug user data on outback servers. In November 2009 Matthew Papakipos, technology conductor for the Chrome OS, claimed that the Chrome OS consumes one-sixtieth a much tug space as Windows 7. [ 16 ] The recovery images Google provides for Chrome OS scope between 1 and 3 GB. [ 17 ] On November 19, 2009, Google released Chrome OS ‘s reference code as the Chromium OS undertaking. [ 18 ] At a November 19, 2009, news conference, Sundar Pichai, at the meter Google ‘s vice president overseeing Chrome, demonstrated an early version of the manoeuver system. He previewed a background which looked identical alike to the Chrome browser, and in addition to the regular browser tab key, besides had application tabs, which take less space and can be pinned for easier access. At the conference, the operate system booted up in seven seconds, a time Google said it would work to reduce. [ 15 ] [ 13 ] [ 19 ] [ 20 ] Additionally, Chris Kenyon, frailty president of the united states of OEM services at Canonical Ltd, announced that Canonical was under sign to contribute technology resources to the project with the intent to build on existing open-source components and tools where feasible. [ 21 ]

early on Chromebooks ( 2010 ) [edit ]

In 2010, Google released the unbranded Cr-48 Chromebook in a pilot burner program. [ 22 ] [ 23 ] The establish date for retail hardware featuring Chrome OS was delayed from former 2010 [ 24 ] until the following year. On May 11, 2011, Google announced two Chromebooks from Acer and Samsung at Google I/O. [ 25 ] [ 26 ] The Samsung model was released on June 15, 2011, but the Acer was delayed until mid-july. [ 27 ] [ 28 ] In August 2011, Netflix announced official documentation for Chrome OS through its stream service, allowing Chromebooks to watch streaming movies and television shows via Netflix. At the prison term, early devices had to use Microsoft Silverlight to play videos from Netflix. [ 29 ] Later in that lapp calendar month, Citrix released a client application for Chrome OS, allowing Chromebooks to entree Windows applications and desktops remotely. [ 30 ] Dublin City University became the first base educational institution in Europe to provide Chromebooks for its students when it announced an agreement with Google in September 2011. [ 31 ]

expansion ( 2012 ) [edit ]

Samsung Chromebook By 2012, demand for Chromebooks had begun to grow, and Google announced a modern range of devices, designed and manufactured by Samsung. In so doing, they besides released the first Chromebox, the Samsung Series 3, which was Chrome OS ‘s entrance into the earth of desktop computers. [ 32 ] Although they were faster than the previous range of devices, they were hush underpowered compared to other desktops and laptops of the time, fitting in more closely with the Netbook market. only months late, in October, Samsung and Google released a newfangled Chromebook at a significantly lower price point ( $ 250, compared to the previous Series 5 Chromebooks ‘ $ 450 ). [ 33 ] It was the beginning Chromebook to use an ARM processor, one from Samsung ‘s Exynos line. To reduce the price, Google and Samsung besides reduced the memory and screen resolution of the device. An advantage of using the ARM processor, however, was that the Chromebook did n’t require a fan. Acer followed promptly after with the C7 Chromebook, priced even lower ( $ 199 ), but containing an Intel Celeron processor. [ 34 ] One celebrated way Acer reduced the cost of the C7 was to use a laptop arduous harrow rather than a solid-state drive. In April 2012, Google made the first update to Chrome OS ‘s user interface since the engage organization had launched, introducing a hardware-accelerated window coach called “ Aura ” along with a conventional taskbar. The additions marked a passing from the operational system ‘s original concept of a individual browser with tabs and gave Chrome OS the attend and feel of a more conventional background operational arrangement. “ In a way, this about feels as if Google is admitting kill here ”, wrote Frederic Lardinois on TechCrunch. He argued that Google had traded its original version of ease for greater functionality. “ That ‘s not inevitably a bad thing, though, and may good help Chrome OS advance more mainstream toleration as fresh users will surely find it to be a more familiar experience. ” [ 35 ] Lenovo and HP followed Samsung and Acer in manufacturing Chromebooks in early 2013 with their own models. [ 36 ] Lenovo specifically targeted their Chromebook at students, headlining their press release with “ Lenovo Introduces Rugged ThinkPad Chromebook for Schools ”. [ 37 ] [ 38 ] When Google released Google Drive, they besides included Drive integration in Chrome OS version 20, released in July 2012. [ 39 ] While Chrome OS had supported Flash since 2010, [ 40 ] by the end of 2012 it had been amply sandboxed, preventing issues with Flash from affecting other parts of Chrome OS. [ 41 ] This affected all versions of Chrome including Chrome OS .

Chromebook Pixel [edit ]

Chromebook Pixel ( Wi-Fi ) open up to this charge, Google had never made their own Chrome OS device. alternatively, Chrome OS devices were much more exchangeable to their Nexus cable of Android phones, with each Chrome OS device being designed, manufactured, and marketed by third-party manufacturers, but with Google controlling the software. however, in February 2013 this changed when Google released the Chromebook Pixel. [ 42 ] The Chromebook Pixel was a departure from previous devices. not entirely was it entirely Google-branded, but it contained an Intel i5 central processing unit, a high-resolution ( 2,560 × 1,700 ) touch screen expose, and came at a price more competitive with business laptops. [ 43 ]

controversial popularity [edit ]

By the end of 2013, analysts were on the fence on the future of Chrome OS. Although there had been articles predicting the death of Chrome OS since 2009, [ 44 ] [ 45 ] [ 46 ] [ 47 ] [ 48 ] Chrome OS device sales continued to increase well year-over-year. In mid-2014, Time magazine published an article titled “ Depending on Who ‘s Counting, Chromebooks are Either an enormous hit or Totally Irrelevant ”, which detailed the differences in public opinion. [ 49 ] This controversy was far spurred by the fact that Intel seemed to decide Chrome OS was a beneficial market for it, holding their own Chrome OS events where they announced new Intel-based Chromebooks, Chromeboxes, and an all-in-one from LG called the Chromebase. [ 50 ] Seizing the opportunity created by the end of life for Windows XP, Google pushed arduous to sell Chromebooks to businesses, offering significant discounts in early on 2014. [ 51 ] Chrome OS devices outsell Apple Macs global for the year 2020. [ 52 ] [ 53 ] [ 54 ]

Pwnium competition [edit ]

In March 2014, Google hosted a chop contest aimed at calculator security experts called “ Pwnium ”. Similar to the Pwn2Own contest, they invited hackers from around the world to find exploits in Chrome OS, with prizes available for attacks. Two exploits were demonstrated there, and a third base was demonstrated at that year ‘s Pwn2Own competition. Google patched the issues within a week. [ 55 ]

Material Design and app runtime for Chrome [edit ]

Although the Google Native Client has been available on Chrome OS since 2010, [ 56 ] there in the first place were few native Client apps available, and most Chrome OS apps were still web apps. however, in June 2014, Google announced at Google I/O that Chrome OS would both synchronize with Android phones to share notifications and begin to run Android apps, installed directly from Google Play. [ 57 ] This, along with the broadening choice of Chromebooks, [ 58 ] provided an matter to future for Chrome OS. At the same time, Google was besides moving towards the then-new Material Design design terminology for its products, which it would bring to its web products equally well as Android Lollipop. [ 59 ] One of the first Material Design items to come to Chrome OS was a new nonpayment wallpaper, [ 60 ] though Google did release some screenshots of a Material Design experiment for Chrome OS that never made it into the stable interpretation. [ 61 ]

Features [edit ]

functionality for small and medium businesses and enterprise [edit ]

Chrome Enterprise [edit ]

Chrome Enterprise, launched in 2017, includes Chrome OS, Chrome Browser, Chrome devices and their management capabilities intended for business manipulation. Businesses can entree the standard Chrome OS features and unlock advanced features for business with the Chrome Enterprise Upgrade. [ 62 ] [ 63 ] Standard features include the ability to sync bookmarks and browser extensions across devices, cloud or native print, multi-layered security system, remote background, and automatic rifle updates. [ 64 ] Advanced features include active Directory consolidation, unified end point management, advanced security security, access to device policies and Google Admin cabinet, guest access, kiosk modality, and whitelisting or blacklisting third-party apps managed on Google Play. [ 65 ] [ 66 ] The education sector was an early adoptive parent of Chromebooks, Chrome OS, and cloud-based calculation. Chromebooks are widely used in classrooms and the advantages of cloud-based systems have been gaining an increased contribution of the market in other sectors as well, including fiscal services, healthcare, and retail. [ 67 ] “ The popularity of swarm calculate and cloud-based services highlights the academic degree to which companies and business processes have become both internet-enabled and dependent. ” [ 68 ] IT managers cite a number of advantages of the mottle that have motivated the move. Among them are advance security, because data is not physically on a single car that can be lost or stolen. [ 69 ] Deploying and managing cloud-native devices is easier because no hardware and software upgrades or virus definition updates are needed and patching of OS and software updates are simpler. Simplified and centralized management decreases operational costs. Employees can securely access files and solve on any machine, increasing the shareability of Chrome devices. Google ‘s Grab and Go broadcast with Chrome Enterprise allows businesses deploying Chromebooks to provide employees entree to a bank of in full charged computers that can be checked out and returned after some time. [ 70 ]

From Chromebooks to Chromebox and Chromebase [edit ]

In an early try to expand its enterprise offerings, Google released Chromebox for Meetings in February 2014. Chromebox for Meetings is a kit for league rooms containing a Chromebox, a television camera, a unit containing both a noise-cancelling microphone and speakers, and a outside control. It supports Google Hangouts meetings, Vidyo video conferences, and league calls from UberConference. [ 71 ] [ 72 ] several partners announced Chromebox for Meetings models with Google, and in 2016 Google announced an all-in-one Chromebase for Meetings for smaller meet rooms. [ 73 ] Google targeted the consumer hardware market with the release of the Chromebook in 2011 and Chromebook Pixel in 2013, and sought entree to the enterprise market with the 2017 release of the Pixelbook. The second-generation Pixelbook was released in 2019. [ 74 ] In 2021 there are several vendors selling all-in-one Chromebase devices. [ 75 ]

enterprise reaction to Chrome devices [edit ]

Google has partnered on Chrome devices with respective leading OEMs, including Acer, ASUS, Dell, HP, Lenovo, and Samsung. In August 2019, Dell announced that two of its popular business-focused laptops would run Chrome OS and come with Chrome Enterprise Upgrade. The latitude 5300 2-in-1 Chromebook Enterprise and Latitude 5400 Chromebook Enterprise were the resultant role of a biennial partnership between Dell and Google. [ 76 ] The machines come with a bundle of Dell ‘s cloud-based accompaniment services that would enable enterprise IT managers to deploy them in environments that besides rely on Windows. [ 77 ] The new laptop cable “ delivers the search colossus ‘s Chrome OS operating system in a shape tailored for security-conscious organizations. ” [ 78 ] other OEMs that have launched devices with Chrome Enterprise Upgrade include Acer and HP. [ 79 ] With a broader range of hardware available, Chrome OS became an option for enterprises wishing to avoid a migration to Windows 10 before Windows 7 defend was discontinued by Microsoft. [ 80 ]

hardware [edit ]

A Chromebook Laptops running Chrome OS are known jointly as “ Chromebooks “. The foremost was the CR-48, a reference hardware design that Google gave to testers and reviewers beginning in December 2010. retail machines followed in May 2011. A year late, in May 2012, a desktop design marketed as a “ Chromebox “ was released by Samsung. In March 2015 a partnership with AOPEN was announced and the first commercial Chromebox was developed. [ 81 ] In early 2014, LG Electronics introduced the foremost device belong to the modern all-in-one form gene called “ Chromebase “. Chromebase devices are basically Chromebox hardware inside a monitor with a built-in camera, microphone and speakers. The Chromebit is an HDMI dongle running Chrome OS. When placed in an HDMI slot on a television fix or computer monitor, the device turns that display into a personal calculator. The first device, announced in March 2015 was an Asus unit of measurement that shipped that November and which reached end of life in November 2020. [ 82 ] Chromebook tablets were introduced in March 2018 by Acer with their Chromebook Tab 10. Designed to rival the Apple iPad, it had an identical filmdom size and settlement and early alike specifications, a celebrated addition was a Wacom-branded stylus that doesn ’ t require a battery or charging. [ 83 ] Chrome OS supports multi-monitor setups, on devices with a video-out port, USB 3.0 or USB-C, the latter being preferable. [ 84 ] On February 16, 2022, Google announced a development translation of Chrome OS Flex —a distribution of Chrome OS that can be installed on conventional personal computer hardware to replace other operating systems such as Windows and macOS. It is similar to CloudReady, a distribution of Chromium OS whose developers were acquired by Google in 2020. [ 85 ] [ 86 ]

software [edit ]

The software and updates are limited in their confirm life. [ 87 ] [ 88 ] Each device model manufactured to run Chrome OS has a different end-of-life date, with all raw devices released in 2020 and beyond guaranteed to receive a minimum of eight years from their date of initial release. [ 89 ] As of Version 78, the device ‘s end-of-life date for software updates is listed in “ About Chrome OS ” – ” Additional Details ”. [ 90 ]

Applications [edit ]

initially, Chrome OS was about a pure thinly node operating organization that relied primarily on servers to host network applications and related data storage. [ 91 ] [ 92 ] Google gradually began encouraging developers to create “ packaged applications ”, and later, Chrome Apps. The latter use HTML5, CSS, Adobe Shockwave, and JavaScript to provide a drug user know close to a native application. [ 93 ] [ 94 ] In September 2014, Google launched App Runtime for Chrome ( beta ), which allowed certain port [ 95 ] Android applications to run on Chrome OS. Runtime was launched with four android applications : Duolingo, Evernote, Sight Words, and Vine. [ 96 ] In 2016, Google made Google Play available for Chrome OS, making most android apps available for supported Chrome OS devices. [ 97 ] In 2018, Google announced plans for Chrome OS support for desktop Linux apps. [ 98 ] This capability was released to the stable distribution channel ( as an choice for most machines ) with Chrome 69 in October 2018, but was still marked as beta. [ 99 ] This feature was officially released with Chrome 91. [ 100 ] By default X11 is not used, [ 101 ] [ better source needed ] while X11 apps can be run. [ 102 ] [ better source needed ] Project Crostini makes X11 shape ( through Wayland ). [ 103 ]

Chrome Apps [edit ]

From 2013 until January 2020, Google encouraged developers to build not barely conventional Web applications for Chrome OS, but Chrome Apps ( once known as Packaged Apps ). [ 104 ] In January 2020, Google ‘s Chrome team announced its purpose to phase out support for Chrome Apps in privilege of “ progressive web applications “ ( PWA ) and Chrome extensions alternatively. [ 105 ] In March 2020, Google stopped accepting new public Chrome Apps for the web shop. [ 106 ] According to Google, general back for Chrome Apps on Chrome OS will remain enable, without requiring any policy set, through June 2022. [ 106 ] From a drug user ‘s position, Chrome Apps resemble conventional native applications : they can be launched outside of the Chrome browser, are offline by nonpayment, can manage multiple windows, and interact with other applications. Technologies employed include HTML5, JavaScript, and CSS. [ 107 ] [ 108 ] [ 109 ]

Integrated media player, file director [edit ]

Google integrates a media player into both Chrome OS and the Chrome browser, enabling users to play back MP3s, view JPEGs, and handle early multimedia files while offline. [ 110 ] It besides supports DRM television. [ 111 ] Chrome OS besides includes an integrated charge coach, resembling those found on other operating systems, with the ability to display directories and the files they contain from both Google Drive and local repositing, arsenic well as to preview and manage file contents using a variety show of Web applications, including Google Docs and Box. [ 112 ] Since January 2015, Chrome OS can besides integrate extra storage sources into the file director, relying on install extensions that use the File System Provider API. [ 113 ]

distant application access and virtual desktop access [edit ]

In June 2010, Google software engineer Gary Kačmarčík wrote that Chrome OS would access remote applications through a engineering unofficially called “Chromoting”, which would resemble Microsoft ‘s Remote Desktop Connection. [ 110 ] The diagnose has since been changed to “Chrome Remote Desktop”, and is like “ running an application via Remote Desktop Services or by first connecting to a host machine by using RDP or VNC ”. [ 114 ] Initial roll-outs of Chrome OS laptops ( Chromebooks ) indicate an interest in enabling users to entree virtual desktop. [ 115 ] [ 116 ]

Android applications [edit ]

At Google I/O 2014, a proof of concept showing Android applications, including Flipboard, running on Chrome OS was presented. In September 2014, Google introduced a beta version of the App Runtime for Chrome ( ARC ), which allows selected Android applications to be used on Chrome OS, using a native Client -based environment that provides the platforms necessary to run Android software. Android applications do not require any modifications to run on Chrome OS, but may be modified to better support a shiner and keyboard environment. At its initiation, Chrome OS support was merely available for selected Android applications. [ 117 ] In 2016, Google introduced the ability to run Android apps on supported Chrome OS devices, with access to Google Play in its entirety. The previous Native Client-based solution was dropped in favor of a container containing Android ‘s frameworks and dependencies ( initially based on Android Marshmallow ), which allows Android apps to have direct access to the Chrome OS platform, and allow the OS to interact with Android contracts such as sharing. Engineering director Zelidrag Hornung explained that ARC had been scrapped due to its limitations, including its incompatibility with the Android Native Development Toolkit ( NDK ), and that it was unable to pass Google ‘s own compatibility test suite. [ 118 ] [ 119 ]

Linux apps [edit ]

All Chromebooks made since 2018, and many earlier models, can run Linux apps. As with Android apps, these apps can be installed and launched alongside early apps. [ 120 ] Google maintains a list of devices that were launched before 2019, which support Linux apps. [ 121 ] [ 122 ] Since 2013, it has been possible to run Linux applications in Chrome OS through the use of Crouton, a third-party arrange of scripts that allows access to a Linux distribution such as Ubuntu. [ 123 ] however, in 2018 Google announced that background Linux apps were officially coming to Chrome OS. [ 124 ] The independent benefit claimed by Google of their official Linux application support is that it can run without enabling developer modality, keeping many of the security features of Chrome OS. It was noticed in the Chromium OS reservoir code in early 2018. [ 125 ] [ 126 ] early parts of Crostini were made available for the Google Pixelbook via the dev channel in February 2018 as depart of Chrome OS version 66, [ 127 ] [ 128 ] and it was enabled by default option via the beta channel for testing on a variety of Chromebooks in August 2018 with translation 69. [ 129 ]

architecture [edit ]

Google ‘s project for supporting Linux applications in Chrome OS is called Crostini, named for the italian bread-based starter, and as a pun on Crouton. Crostini runs a virtual machine through a virtual machine monitor called crosvm, which uses Linux ‘s built-in KVM virtualization cock. Although crosvm supports multiple virtual machines, the one used for running Linux apps, Termina, contains a basic Chrome OS kernel and userland utilities, in which it runs containers based on Linux containers ( specifically LXD ). [ 10 ]

architecture [edit ]

Chrome OS is built on peak of the Linux kernel. originally based on Ubuntu, its base was changed to Gentoo Linux in February 2010. [ 130 ] For Project Crostini, as of Chrome OS 80, Debian 10 ( Buster ) is used. [ 131 ] In preliminary blueprint documents for the Chromium OS open-source project, Google described a three-tier architecture : firmware, browser and window director, and system-level software and userland services. [ 132 ]

  • The firmware contributes to fast boot time by not probing for hardware, such as floppy disk drives, that are no longer common on computers, especially netbooks. The firmware also contributes to security by verifying each step in the boot process and incorporating system recovery.[132]
  • System-level software includes the Linux kernel that has been patched to improve boot performance. Userland software has been trimmed to essentials, with management by Upstart, which can launch services in parallel, re-spawn crashed jobs, and defer services in the interest of faster booting.[132]
  • The window manager handles user interaction with multiple client windows (much like other X window managers).[132]

security [edit ]

In March 2010, Google software security mastermind Will Drewry discussed Chrome OS security. Drewry described Chrome OS as a “ case-hardened ” function system featuring auto-updating and sandbox features that would reduce malware exposure. He said that Chrome OS netbooks would be shipped with Trusted Platform Module ( TPM ), and include both a “ trust boot path ” and a physical trade under the barrage compartment that activates a “ developer mode ”. That mode drops some specialized security functions but increases developer tractability. Drewry besides emphasized that the open-source nature of the operational system would contribute greatly to its security by allowing constant developer feedback. [ 133 ] At a December 2010 urge conference, Google declared that Chrome OS would be the most guarantee consumer function system due in part to a verified boot ability, in which the initial boot code, stored in read-only memory, checks for arrangement compromises. [ 134 ] In the following nine years, Chrome OS has been affected by 55 attested security flaws of any asperity, [ 135 ] compared with over 1,100 affecting Microsoft Windows 10 in the five years to the end of 2019 [ 136 ] and over 2,200 affecting Apple OS X in 20 years. [ 137 ]

Shell access [edit ]

Chrome OS includes the Chrome Shell, or “ crosh ”, [ 138 ] which documents minimal functionality such as ping at crosh start-up. In developer mode, a full-featured bash [ 139 ] shell ( which is supposed to be used for development purposes [ 140 ] ) can be opened via VT -2, and is besides accessible using the crosh command shell. [ 141 ] To access wide privileges in blast ( e.g. sudo ) a solution password is requested. For some time the default was “ chronos ” in Chrome OS and “ facepunch ” in Chrome OS Vanilla [ 142 ] and late the default was empty, and instructions on updating it were displayed at each login .

Open beginning [edit ]

Chrome OS is partially developed under the open-source Chromium OS undertaking. [ 143 ] As with other open-source projects, developers can modify the code from Chromium OS and build their own versions, whereas Chrome OS code is merely supported by Google and its partners and only runs on hardware designed for the aim. Unlike Chromium OS, Chrome OS is mechanically updated to the latest version. [ 15 ]

Chrome OS on Windows [edit ]

On Windows 8, exceptions allow the default option desktop world wide web browser to offer a discrepancy that can run inside its full-screen “ Metro “ shell and access features such as the Share charm, without necessarily needing to be written with Windows Runtime. Chrome ‘s “ Windows 8 modality ” was previously a tablet-optimized version of the standard Chrome interface. In October 2013, the manner was changed on Developer groove to offer a variant of the Chrome OS background. [ 144 ] [ 145 ] [ 146 ] [ 147 ] [ 148 ]

design [edit ]

early in the project, Google provided publicly many details of Chrome OS ‘s design goals and direction, [ 149 ] although the caller has not followed up with a technical description of the completed operational arrangement .

User interface [edit ]

design goals for Chrome OS ‘s user interface included using minimal screen outer space by combining applications and criterion Web pages into a single tab key strip, rather than separating the two. Designers considered a reduced window management schema that would operate merely in full-screen modality. secondary coil tasks would be handled with “ panels ” : float windows that dock to the bottom of the screen for tasks like chat and music players. burst screens were besides under consideration for viewing two pieces of content side by slope. Chrome OS would follow the Chrome browser ‘s practice of leveraging HTML5 ‘s offline modes, background work, and notifications. Designers proposed using search and pin tab key as a means to promptly locate and access applications. [ 150 ]

translation 19 window coach and graphics engine [edit ]

On April 10, 2012, a new build up of Chrome OS offered a choice between the original full-screen windowpane interface and overlap, re-sizable windows, such as found on Microsoft Windows and Apple ‘s macOS. [ 151 ] The sport was implemented through the Ash window director, which runs atop the Aura hardware-accelerated graphics engine. The April 2012 upgrade besides included the ability to display smaller, overlapping browser windows, each with its own translucent tab key, browser tabs that can be “ pluck ” and dragged to newly positions or merged with another yellow journalism plunder, and a mouse-enabled shortcut list across the bottom of the screen. One icon on the job barricade shows a list of install applications and bookmarks. Writing in CNET, Stephen Shankland argued that with overlapping windows, “ Google is anchoring itself into the past ” as both io and Microsoft ‘s Metro interface are largely or entirely full-screen. even so, “ Chrome OS already is different enough that it ‘s best to preserve any familiarity that can be preserved ”. [ 151 ] [ 152 ] [ 153 ]

Printing [edit ]

Google Cloud Print is a Google service that helps any application on any device to print on defend printers. While the cloud provides about any connect device with information access, the undertaking of “ developing and maintaining print subsystems for every combination of hardware and operational system—from desktops to netbooks to mobile devices—simply is n’t feasible. ” [ 154 ] [ 155 ] The cloud serve requires initiation of a piece of software called proxy, as part of the Chrome OS. The proxy registers the printer with the service, manages the print jobs, provides the printer driver functionality, and gives status alerts for each job. [ 156 ] In 2016, Google included “ native CUPS Support ” in Chrome OS as an experimental feature that may finally become an official feature. With CUPS support turned on, it becomes possible to use most USB printers even if they do not support Google Cloud Print. [ 157 ] [ 158 ] Google announced that Google Cloud Print would nobelium long be supported after December 31, 2020, and that the on-line service would not be available as of January 1, 2021. [ 159 ]

Link handling [edit ]

Chrome OS was designed to store user documents and files on distant servers. Both Chrome OS and the Chrome browser may introduce difficulties to end-users when handling specific file types offline ; for model, when opening an effigy or document residing on a local anesthetic storehouse device, it may be ill-defined whether and which particular Web application should be automatically opened for viewing, or the treat should be performed by a traditional application acting as a preview utility. Matthew Papakipos, Chrome OS mastermind conductor, noted in 2010 that Windows developers have faced the lapp fundamental problem : “ Quicktime is fighting with Windows Media Player, which is fighting with Chrome. ” [ 12 ]
Chrome OS uses the lapp passing system as Google Chrome : there are three distinct channels : stable, Beta, and Developer preview ( called the “ Dev ” duct ). The stable distribution channel is updated with features and fixes that have been thoroughly tested in the Beta impart, and the Beta channel is updated approximately once a calendar month with stable and complete features from the Developer groove. New ideas get tested in the Developer channel, which can be very fluid at times. [ 160 ] [ 161 ] A fourth fink transmit was confirmed to exist by Google Developer Francois Beaufort and hacker Kenny Strawn, by entering the Chrome OS beat in developer manner, typing the command shell to access the bash plate, and finally entering the command update_engine_client -channel canary-channel -update. It is possible to return to the verify boot mode after entering the canary channel, but the transmit updater disappears and the only way to return to another distribution channel is using the “ pressure-wash ” factory reset. [ 162 ]

reception [edit ]

At its debut, Chrome OS was viewed as a rival to Microsoft, both directly to Microsoft Windows and indirectly the company ‘s news march and spreadsheet applications—the latter through Chrome OS ‘s reliance on obscure calculate. [ 163 ] [ 164 ] But Chrome OS engineering director Matthew Papakipos argued that the two manoeuver systems would not fully overlap in functionality because Chrome OS is intended for netbooks, which lack the computational office to run a resource-intensive program like Adobe Photoshop. [ 12 ] Some observers claimed that other operating systems already filled the niche that Chrome OS was aiming for, with the add advantage of supporting native applications in addition to a browser. Tony Bradley of PC World wrote in November 2009 :

We can already do most, if not all, of what Chrome OS promises to deliver. Using a Windows 7 or Linux-based netbook, users can simply not install anything but a web browser and connect to the huge align of Google products and other web-based services and applications. Netbooks have been successful at capturing the low-end personal computer marketplace, and they provide a web-centric calculation have today. I am not certain why we should get excited that a year from now we ‘ll be able to do the same thing, but locked into doing it from the fourth-place world wide web browser. [ 165 ]

In 2016, Chromebooks were the most democratic computer in the US K–12 education market. [ 166 ] By 2017, the Chrome browser had risen to become the phone number one browser used worldwide. [ 167 ] In 2020, Chromebooks became the second most-popular end-user oriented OS ( growing from 6.4 % in 2019 to 10.8 % in 2020 ). The majority of increase came at Windows expense ( which fell from 85.4 % in 2019 to 80.5 % in 2021 ). [ 168 ]

relationship to Android [edit ]

Google ‘s offer of two open-source operating systems, Android [ 169 ] and Chrome OS, has drawn some criticism despite the similarity between this position and that of Apple Inc. ‘s two operating systems, macOS and io. Steve Ballmer, Microsoft CEO at the time, accused Google of not being able to make up its thinker. [ 170 ] Steven Levy wrote that “ the dissonance between the two systems was apparent ” at Google I/O 2011. The event featured a day by day press conference in which each team drawing card, Android ‘s Andy Rubin and Chrome ‘s Sundar Pichai, “ unconvincingly tried to explain why the systems were n’t competitive ”. [ 171 ] Google co-founder Sergey Brin addressed the question by saying that owning two promising operating systems was “ a problem that most companies would love to face ”. [ 171 ] Brin suggested that the two operating systems “ will likely converge over time ”. [ 172 ] The speculation over convergence increased in March 2013 when Chrome OS headman Pichai replaced Rubin as the senior frailty president of the united states in charge of Android, thereby putting Pichai in charge of both. [ 173 ] The kinship between Android and Chrome OS became closer at Google I/O 2014, where developers demonstrated native Android software running on Chrome OS through a native Client -based runtime. [ 117 ] [ 174 ] In September 2014, Google introduced a beta version of the App Runtime for Chrome ( ARC ), which allows selected Android applications to be used on Chrome OS, using a native Client-based environment that provides the platforms necessary to run Android software. Android applications do not require any modifications to run on Chrome OS, but may be modified to better support a mouse and keyboard environment. At its introduction, Chrome OS support was only available for selected Android applications. [ 117 ] In October 2015, The Wall Street Journal reported that Chrome OS would be folded into Android so that a single OS would result by 2017. The leave OS would be Android, but it would be expanded to run on laptops. [ 175 ] [ 176 ] Google responded that while the company has “ been working on ways to bring together the best of both operating systems, there ‘s no design to phase out Chrome OS ”. [ 177 ] In 2016, Google introduced the ability to run Android apps on support Chrome OS devices, with access to Google Play in its entirety. The former Native Client-based solution was dropped in favor of a container containing Android ‘s frameworks and dependencies ( initially based on Android Marshmallow ), which allows Android apps to have direct access to the Chrome OS platform, and allow the OS to interact with Android contracts such as sharing. Engineering conductor Zelidrag Hornung explained that ARC had been scrapped due to its limitations, including its incompatibility with the Android Native Development Toolkit ( NDK ), and that it was unable to pass Google ‘s own compatibility test suite.
