What are the important topologies for networks?
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
