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.
