Google



by Ahmad Fawwazuddin

Google Inc. is an American public corporation specializing in Internet search. It also generates profits from advertising bought on its similarly free-to-user e-mail, online mapping, office productivity, social networking and video-sharing services. Advert-free versions are available via paid subscription. Google has more recently developed an open source web browser and a mobile phone operating system.

The Google web search engine is the company's most popular service. According to market research published by comScore in November 2009, Google is the dominant search engine in the US market, with a market share of 65.6%.[74] Google indexes billions of Web pages, so that users can search for the information they desire, through the use of keywords and operators, although at any given time it will only return a maximum of 1,000 results for any specific search query. Google has also employed the Web Search technology into other search services, including Image Search, Google News, the price comparison site Google Product Search, the interactive Usenet archive Google Groups, Google Maps, and more.
In early 2006, the company launched Google Video, which allowed users to both upload videos, and search and watch videos from the larger Internet.[75] In 2009 uploads to Google video were discontinued.[76]

Google has also developed several desktop applications, including Google Desktop, Picasa, SketchUp and Google Earth, an interactive mapping program powered by satellite and aerial imagery that covers the vast majority of the planet. Many major cities have such detailed images that one can zoom in close enough to see vehicles and pedestrians clearly. Consequently, there have been some concerns about national security implications; contention is that the software can be used to pinpoint with near-precision accuracy the physical location of critical infrastructure, commercial and residential buildings, bases, government agencies, and so on. However, the satellite images are not necessarily frequently updated, and all of them are available at no charge through other products and even government sources; the software simply makes accessing the information easier. A number of Indian state governments have raised concerns about the security risks posed by geographic details provided by Google Earth's satellite imaging

Google Translate aka Google Language Tools is a server-side machine translation service, which can translate 35 different languages to each other, forming 595 language pairs. Browser extension tools (such as Firefox extensions) allow for easy access to Google Translate from the browser. The software uses corpus linguistics techniques from translated documents, (such as United Nations documents, which are professionally translated) to extract translations accurate up to 88 percent. A "suggest a better translation" feature appears with the original language text in a pop-up text field, allowing users to indicate where the current translation is incorrect or else inferior to another translation.

On 1 September 2008, Google pre-announced the upcoming availability of Google Chrome, an open-source web browser,[84] which was released on 2 September 2008.

On 7 July 2009, Google announced the project to develop Google Chrome OS, an open-source Linux-based operating system in a "window of opportunity".
