Network Topology means the layout or shape of the network.  The most common types of network are Ring, Bus and Star.

See the excellent Flash movies at: http://www.ictgcse.org.uk/th_topo1.htm

+   Easy and expensive to install (the least amount of cable required)

-  If the main cable fails, all the computers will be affected

-  The performance of the network slows down when there are more users

+  Data traffic is fast because it flows only in one direction

-  If the cable fails, all the workstations are affected

+  There is much less impact on performance when there are a lot of users on the network

+  A cable failure will only affect one workstation

-  Lots of cable is used, which is expensive

-  It requires a "hub" at the file server to control all the cables
