Can computer networks be divided into four topologies (mesh, cellular, star and bus)?

It is not possible for networks to be divided into four different network topologies. In the example, the network may be divided into a mesh, cellular, star, and bus. This cannot be done in actual.

There are a lot of people who have associated networks to anything that is related to Telco companies or to computers but networks may be formed anywhere. The word network actually means an arrangement of some sort composing of horizontal and vertical lines.

A network may also refer to a group of people or things that are all connected to each other because of different reasons. The computer network is often used by people in order to share resources with each other and to provide different data as they see fit.
