 What are a client and a server?

In general, computing machines connected together on networks can be categorized into two types, servers and clients.



Resources are controlled by the file server in a client/server networker.


Clients

A client can be a machine or a program

A client program is a program that allows the user to make requests

A client, whether it is a machine or a program, is an appliance and a way to make requests through the web

Servers

A server is a computer program NOT a Device

High-performance computers are called servers because they run server programs

Severs provide functionality and server other programs called clients

A single server can serve multiple clients at the same time.

We can run multiple servers on one single machine

There are several types of servers:

Web servers

Apache

Serve HTTP requests

Database server:

  • A server can contain web resources, host web applications, stores user and program data, etc.
  • It is used to serve hundreds of thousands of clients.
  • A server is always listening for requests, and as soon as it receives one, responds with a message.
