Search engines are nothing but the computer server. Daily we are using search engines and how many of them know how this things work perfectly? Let’s learn.
Search engines are the type of server. This server is still connects to other small servers and this is connected to their child server And the process is going on.
Centralized servers are the head of all the servers which can hold the information about all sub servers and child servers of those sub servers and also contents in those servers.
The purpose of search engines to serve the user with relevant resources and those should be worthy. Same information are given in many websites but some of them are getting displayed that’s because of indexing.
Web spider is the bots(computer program) the purpose of bot is to index the page. Indexing is start mostly from most popular one to least accordingly.
The bots catch the pages related to same topics and index those in some order. The process of catching the page from different server and indexing it is called crawling. The pages are crawl but they are still in same server.
