Google Inc. is an American multinational corporation specializing in Internet-related services and products. These include search, cloud computing, software and online advertising technologies.[6] Most of its profits derive from AdWords.[7][8]
Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. Together they own about 16 percent of its stake. They incorporated Google as a privately held company on September 4, 1998. An initial public offering followed on August 19, 2004. Its mission statement from the outset was "to organize the world's information and make it universally accessible and useful",[9] and its unofficial slogan was "Don't be evil".[10][11] In 2006 Google moved to headquarters in Mountain View, California.
Rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Google's core search engine. It offers online productivity software including email, an office suite, and social networking. Desktop products include applications for web browsing, organizing and editing photos, and instant messaging. The company leads the development of the Android mobile operating system and the browser-only Google Chrome OS[12] for a specialized type of netbook known as a Chromebook. Google has moved increasingly into communications hardware: it partners with major electronics manufacturers in production of its high-end Nexus devices and acquired Motorola Mobility in May 2012.[13] In 2012, a fiber-optic infrastructure was installed in Kansas City to facilitate a Google Fiber broadband service.[14]The corporation has been estimated to run more than one million servers in data centers around the world[15] and to process over one billion search requests[16] and about twenty-four petabytes of user-generated data each day.[17][18][19][20] In December 2012 Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger.[21] Google ranks second in the BrandZ brand equity database.[22] Its market dominance has led to criticism over issues including copyright, censorship, and privacy
internet explorer
Internet Explorer, commonly abbreviated IE or MSIE) is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems, starting in 1995. It was first released as part of the add-on package Plus! for Windows 95 that year. Later versions were available as free downloads, or in service packs, and included in the OEM service releases of Windows 95 and later versions of Windows.
Internet Explorer is one of the most widely used web browsers, attaining a peak of about 95% usage share during 2002 and 2003.[4] Its usage share has since declined with the launch of Safari (2003), Firefox (2004), and Google Chrome (2008), each of which now has significant market share. Estimates for Internet Explorer's overall market share range from 27.4% to 54.13%, as of October 2012 (browser market share is notoriously difficult to calculate). Microsoft spent over US$100 million per year on Internet Explorer in the late 1990s,[5] with over 1000 people working on it by 1999.[6]
Since its first release, Microsoft has added features and technologies such as basic table display (in version 1.5); XMLHttpRequest (in version 5), which aids creation of dynamic web pages; and Internationalized Domain Names (in version 7), which allow Web sites to have native-language addresses with non-Latin characters. The browser has also received scrutiny throughout its development for use of third-party technology (such as the source code of Spyglass Mosaic, used without royalty in early versions) and security and privacy vulnerabilities, and both the United States and the European Union have alleged that integration of Internet Explorer with Windows has been to the detriment of other browsers.
The latest stable release is Internet Explorer 10, with a new interface allowing for use as both a desktop application, and as a Windows 8 application.
Versions of Internet Explorer for other operating systems have also been produced, including an Xbox 360 version called Internet Explorer for Xbox and an embedded OEM version called Pocket Internet Explorer, later rebranded Internet Explorer Mobile, which is currently based on Internet Explorer 9 and made for Windows Phone, Windows CE, and previously, based on Internet Explorer 7 for Windows Mobile. It remains in development alongside the desktop versions. Internet Explorer for Mac and Internet Explorer for UNIX (Solaris and HP-UX) have been discontinued.
