Definition: Bus Topology

In Bus topology or bus network several devices/computers/workstations (generally referred as nodes) are connected to a single cable. It is done where the network contains less number of devices (for example LAN setup in small offices). The main disadvantage of bus network is that connectivity failure in any single segment of the bus leads to connectivity failure of entire network.

a)      It is easy to setup and expand.

b)      It costs less and the cable length required is also very small.

c)       Plugging and unplugging of a device doesn’t affect other connections.

Disadvantages of bus network:

a)      There is a limit on cable length and load on the system

b)      Any problem in the central cable leads to disconnection of the entire network.

c)       Security is the prime concern in such type of systems as each system receive signals sent by the source.
