| A web browser built for speed, simplicity, and security |
Google Chrome is a freeware web browser developed by Google. It was first released as a beta version for Microsoft Windows on September 2, 2008, and as a stable public release on December 11, 2008.
As of July 2014, StatCounter estimates that Google Chrome has a 45% worldwide usage share of web browsers, indicating that it is the most widely used web browser in the world. Google releases the majority of Chrome's source code as an open-source project Chromium. A notable component that is not open source is the built-in Adobe Flash Player.
Development
Chrome was assembled from 25 different code libraries from Google and third parties such as Mozilla's Netscape Portable Runtime, Network Security Services, NPAPI, Skia Graphics Engine, SQLite, and a number of other open-source projects. The V8 JavaScript virtual machine was considered a sufficiently important project to be split off (as wasAdobe/Mozilla's Tamarin) and handled by a separate team in Denmark coordinated by Lars Bak at Aarhus. According to Google, existing implementations were designed "for small programs, where the performance and interactivity of the system weren't that important", but web applications such as Gmail "are using the web browser to the fullest when it comes to DOM manipulations and JavaScript", and therefore would significantly benefit from a JavaScript engine that could work faster.
Chrome uses the Blink rendering engine to display web pages. Based on WebKit, Blink only uses WebKit's "WebCore" components while substituting all other components, such as its own multi-process architecture in place of WebKit's native implementation.
Chrome is internally tested with unit testing, "automated user interface testing of scripted user actions", fuzz testing, as well as WebKit's layout tests (99% of which Chrome is claimed to have passed), and against commonly accessed websites inside the Google index within 20–30 minutes.Google created Gears for Chrome, which added features for web developers typically relating to the building of web applications, including offline support. However, Google phased out Gears in favor of HTML5.
On January 11, 2011 the Chrome product manager, Mike Jazayeri, announced that Chrome would remove H.264 video codec support for its HTML5 player, citing the desire to bring Google Chrome more in line with the currently available open codecs available in the Chromium project, which Chrome is based on. Despite this, on November 6, 2012, Google released a version of Chrome on Windows which added hardware-accelerated H.264 video decoding. In October 2013, Cisco announced that it was open-sourcing its H.264 codecs and will cover all fees required. On February 7, 2012, Google launched Google Chrome Beta for Android 4.0 devices. On many new devices with Android 4.1 and later preinstalled, Chrome is the default browser. On April 3, 2013, Google announced that it would fork the WebCore component of WebKit to form its own layout engine known as Blink. The aim of Blink will be to give Chrome's developers more freedom in implementing its own changes to the engine, and to allow its codebase to be trimmed of code that is unnecessary or unimplemented by Chrome.
Security
Google Chrome for Education uses security technologies like Safebrowsing, sandboxing, and auto-updates to protect your school from malicious sites, viruses, malware and phishing attacks. Our cross-site scripting protects against sites that try to steal teacher and student data.
Stability
Chrome’s multi-process architecturemeans that when one tab crashes, it does not bring down the entire browser. Prior to every Chrome update, we'll run thousands of continuous automation tests and collect data from our Development and Beta channels to improve stability.
Compatibility
Always up to date with modern web standards, Chrome lets you run the latest cloud apps. If your school needs a legacy browser to run older applications, try Chrome’s Legacy Browser Support, which helps IT deploy Chrome while supporting an older browser.
Speed
Chrome is built to be fast in every way – starting up from the desktop, loading websites, and running complex, business web apps. With every new release, Chrome continues to improve its Octane score, a benchmark for JavaScript speed.
Productivity
Users can sign-in to Chrome to access their apps, bookmarks, extensions, and other web settings. That means when your students leave school, they can still access everything they need to complete assignments.
Privacy
Chrome puts you in control of your private information while helping protect the information you share when you’re online. You can control privacy preferences from the Options dialog, under the Privacy section located at the top of the Under the Hood tab.
