What is a topology?

Topology of a network is defined as the geometric representation of the relationship of all

the links and linking devices (node) to one another.Four basic topologies are star, bus, ring and mesh.

Star- Here each device has a dedicated point to point link only to a central controller called hub.

Bus- It is multipoint. One long cable acts as a backbone to link all the devices in the network. Ring- Here each device has a dedicated point to point connection only with the two devices on either side of it.

Mesh- Here every device has a dedicated point to point link to every other device.
