List any two disadvantages of bus topology. 
by

1 Answer

Answer :

Disadvantages of bus topology. 1. Heavy network traffic slows down the bus speed .In bus topology only one computer can transmit & other have to wait till their turn comes & there is no co-ordination between computers for reservation of transmitting time slot. 2. The BNC connector used for expansion of the bus attenuates the signal considerably. 3. A cable break or loose BNC connectors will cause reflections & bring down the whole network causing all network activity to stop.
