BUS topology: In this each computer is directly connected to primary network CABLE in a single line.
Advantages: Inexpensive, easy to install, simple to understand, easy to extend.

STAR topology: In this all computers are connected using a central hub.
Advantages: Can be inexpensive, easy to install and RECONFIGURE and easy to trouble shoot physical problems.

RING topology: In this all computers are connected in loop.
Advantages: All computers have equal access to network MEDIA, installation can be simple, and signal does not DEGRADE as much as in other topologies because each computer regenerates it.
