What is Server?
In computing, a server is a piece of computer hardware or software that provides functionality for other programs or devices, called “clients”. This architecture is called the client–server model.
Why we need Server for our organization?
A server helps organize the IT management of your company by managing user permissions, software, and security. If you have more than a handful of computers, a server can help you save time, maximize productivity, prevent security breaches, and recover if disaster strikes.
