Hi dear , Well , 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. 1. Googlebot, Google’s Web Crawler 2.Google’s Indexer 3.Google’s Query Processor I hope it will work for you.....
