What is a computer network?

A computer network is a collection of computer and network equipment connected via communication channels into a single system. To create a computer network, we need the following components:

  • Computers that can connect to the network (for example, via the network card that every modern PC has).
  • Transmission medium or communication channels (cable, satellite, telephone, fiber-optic and radio channels).
  • Network equipment (such as a switch or router).
  • Network software (usually included in the operating system or left with the network hardware).

As a rule, computer networks are classified according to two criteria: general networks (user) and special networks (professional).

Wireless communication technology is a modern alternative to traditional wired networking. It is a network set up by using radio signal frequency to communicate among computers and other network devices.



This animation looks at how mobile networks continue to grow and evolve in response to the growth connections and mobile data and how good mobile network policy supports access to services.
