In other words Googleblots are spiders scurrying the strands of cyber space to gather information uploaded on the World Wide Web everyday.

How Google process a query?
When a user enters a word or phrase in the user box it goes to the Google web server from where it goes to the index server. In the index server all the information is arranged in alphabetical order. The index server matches the query with words of stored data. Thereafter index server sends the query to the doc server and from here snippets are generated to describe each result.
