The Advantages and Disadvantages of Each Type of Topology


Bus Topology

Uses the least amount of cable.

Media is inexpensive, simple and reliable.

Is easy to extend.

Hardware bugs are difficult to isolate.

Does not adequately support large number of I/O requests from users.

Cable break can affect many users.

Ring Topology

Networks can cover greater distances.

Performance is even despite many users.

Expanding the system can be costly.

Network reconfiguration disrupts operation.

Star Topology

New computers can be easily added.

Cable layouts are easy to modify.

Failure of one computer does not affect the rest of the network.

Uses a large amount of cable.

If the centralized point fails, the network fails.
