Network Topologies
Ring Network
Consists of a number of nodes connected together without the need for a fileserver.
Each node is connected to two adjacent nodes.
A special message called a token is passed from node to node.
-
Disadvantages
If a single machine is switched off, the network doesn't work.
-
-
BUS Network
All nodes are connected onto the main cable known as the Backbone.
Data can be transmitted in both directions on the main cable. At the ends of the cable are terminators.
-
Disadvantages
If there is a problem with the central cable, the entire network stops working.
If there are a lot of workstations on the network, data can travel slowly.
-
STAR Network
There is a central fileserver whereby each node is connected to the fileserver by its own cable.
The host computer controls all communication on the network such that if a node wishes to communicate with another node this must be done via the fileserver.
Advantages
Very reliable. If one connection fails, it does not affect other users.
