hmmmm...this is a really tough question. I guess in short google is search engine? lol what does a search engine does? They search..you type in things that you want to search and they will find out all relevant results for you.
Google is world's biggest Search Engine... I guess this is what you are asking "How Google Works ..?" Answer: Google runs on a distributed network of thousands of low-cost computers and can therefore carry out fast parallel processing. 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.
