A server is a computer designed to process requests and deliver data to another
computer (clients) over the internet or a local network. It's an instance of a
computer program that accepts and responds to requests made by clients.
Types of Servers

A mail server receives incoming email from local users and remote senders and forwards outgoing email for delivery.
Choosing the right Server
There are many factors to consider while selecting a specific server. When choosing a server, it is important to evaluate the need, features, and cost of a server. Below are some questions that you may need to ask yourself before choosing a server:
• Are you buying a server for file sharing or something else?
• Are you going to use your server for data backup?
• Will your server be used for email?
• Do you need to connect to the server remotely?
• How much space or storage do you need to accommodate a server?
Answering these questions will give a clear idea of the kind of server you need, including features, storage, workloads, availability, and cost.
