Components of Computer Network 



The  components that make up a computer network are - 

1. Client 
2. Server

Client - Client is a computer that retrieves information from or uses resources provided by the server or main computer.

Server - A server is an instance of a computer program that accepts and responds to requests made by client. 
Servers are used to manage network resources.

Middleware is the software that connects two otherwise separate applications.

Most networks today, including all computers on the Internet, use the TCP/IP protocol as the standard for how to communicate on the network. 

In the TCP/IP protocol, the unique identifier for a computer is called its IP address. TCP - is responsible for verifying the correct delivery of data from client to server. IP - is responsible for moving packet of data from node to node.
