A computer is single user request response Example ( a user need some document in a computer it opens and views on single screen) on other hand server used in a network responses the more over 100+ Same request Example (Multiple user can view same Document without any Trouble on its own devices)
Reason why we call it Servers 
-> Both devices are same but it different by it’s working. That’s why we call by it’s working.
-> Computer is Less Configuration , Whereas Server is High Configuration in Shared Network.
-> Server is Fixed at One place it not Moves again & again , But Computer,Laptop & Mobile are shifted its location.

How Severs Works ?

Any Servers works nearly Similar Its Response to the Request , Any Users Request Some Data in the form of HTTPS the Server Response to it in the Same Manner If data finds its show else it Response some errors which data not found you request.

In Above Diagram it represent the Web Servers Working. The page Request Response the by the Server. the Simple Static Page Without Database.

In Above Diagram it represent the Web Servers Working With Database. The Dynamic Website Required Database for Records information data for more lite site. In this Page is Process in Web Server and added with data and then Its goes back to Client System.Its too fast process . sometime we received server cache page.
