Star Topology

What is Star Topology?

This is a computer network that involves a centralized host computer connected to a number of smaller computer systems with a central device called Hub or Switch. The smaller computer systems communicate with one another through this central device and usually shares the host computer's database. Any computer can communicate with any other computer in the network.
Twisted pair cable and RJ-45 connector is used in this topology.
Following are the some advantages and disadvantages of Star Topology.

Advantages:

• If any terminal becomes defective, it does not affect any other terminal of this network.
• The central computer controls the flow of the data.
• There is no chance of data collision in Star Topology.

Disadvantages:

• This type of topology is expensive because each terminal is connected with a separate cable.
• If the central device is shutdown, the whole network will suffer.
