The way in which the devices are connected in a network both physically and logically is referred to as Network Topology.

There are two ways of defining network topology. They are:

  • Physical Topology
  • Logical Topology or, Signal Topology

Introduction to Computer Networks

A group of devices when connected together to share resources forms a computer network.

Computer Network are required so that the devices can:

  • can communicate with each other
  • share resources such as files, printers, databases and much more
  • transfer data from one to another.

Data Communication

The exchange of data between two devices via some form of transmission medium is known as data communication.
