At this time if you want to buy any thing or if you want learn new things we look Internet. Just think how internet giving these details to us…? Because of Search Engines only. who is Search Engines…? Search engines nothing but our Google, Yahoo, bing, Ask etc.,
When ever i am searching something in internet. I thought how Google knows all these details not only single topic and how these details google collected from different websites(Sources)…? For example in Google database some Lac’s of Crores pages or documents are there. With in milliseconds how it will give exact information what you want. That is the power of Google Search Engines. Now we are going to have a look how search engines work….?
In World Wide Web (WWW) contains some billions of pages with different topics. Each page consist there own unique document. What ever we prepare blogs or pages etc., will placed in World wide web. Every day 24 X 7 google Crawler scans the world wide web. Always google crawler crawls what are the new updates this sec …? Because every micro second new updates happened in World wide like News, Articles, Products lunching, Movie updates etc.,
We can check at which time google crawls our website, For Example cache:www.amazon.com
After crawling, the crawler will sends the data to Store. All the documents, Files, images, Videos etc., will stored in Store. In Store all data’s are mixed for example Agriculture files, Politics, Engineering, Movies, Songs, online purchase etc., Indexer will segregate the based on niche (Topic). Then indexer remove some of the file like empty pages, virus, Under construction pages etc., After removing some files then indexer sorted based on Contents.
We can check specific website how many pages it consists For example site:www.amazon.com
When ever we entered keywords in Google search engine it will check with different factors of google algorithm based on it will give the preference of pages. Google algorithm place major role in Search Engines Optimizations.
Search Engine Architecture with practical example:
Suppose you are planning to make one library. First we need go to Books market area and we must visit different book shops. From each book shop you will collect some books and with the help of vehicle you shifted to one store. Then Librarian segregates the books based on subjects or topics. Then he will arrange in racks with unique numbers based on topics. When ever students want books they will come and they will ask to librarian then he will check in his system, then librarian will inform rack number, then student will go and collect the book.
