Number of computer networks using wireless methods to move data from one system to another, but many networks still systems combine a kind of cabling (copper or optic fibre), use. Thus, the cables and equipment or signals with each other to a network wireless is known as the topology of the network. Historic network topologies include bus, ring and star, hybrid during modern topologies, include mesh, point-to-multipoint and point.

Historical topologies

Bus:

Topology Bus uses a single cable bus, which connects all computers in a row and the data on the bus together. At the end of the cable data reflect and create unnecessary traffic preventing the need for bus terminators of topology at each end of the cable.

Ring:

A ring topology is a topology by bus, with the exception that it connects all computers with a cable of the central ring, so that it does not lead on the bus is and requires no notice. Data flows in a circle from one computer to another in the same direction.

* If a cable is broken at any point in a bus or ring topology does not work across the network. The end quashed in a topology of bus created data because the endpoint is mirroring between the connected computers, is more connected to the network. A cable broke in a ring topology breaks the circuit, stopping the flow of data.  Read more...
