How Google works.
Google was founded in September 1998 and has now become one of the most well-known and recognized internet search browsers. Google Inc is an American public corporation that is now not only known for its search engine, but for its e-mail, online mapping, office productivity, social networking and video sharing, but how does such a large internet base work?
Google runs by using parallel processing with three distinct parts. According to Googleguide.com, this process can be explained as “a distributed network of thousands of low-cost computers. Parallel processing is a method of computation in which many calculations can be performed simultaneously, significantly speeding up data processing. Google has three distinct parts:
· Googlebot, a web crawler that finds and fetches web pages.
· The indexer that sorts every word on every page and stores the resulting index of words in a huge database.
· The query processor, which compares your search query to the index and recommends the documents that it considers most relevant.”
How the pages that come up from your search work.
Google uses a process simply known as “page rank,” that adds up a number of different factors to display what hierarchy different sites appear. Google’s “page rank” gives each website a ranking from 1-10 based on certain criteria. The more relevant links you have on your website, the more votes Google will award to your site. More links=more votes. In addition, the higher the points of the links you attach to your website, the more votes your website will receive.
