How Google works . Save the image and zoom it .......!!!!!!

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.
