Bus
Topology
A bus topology consists
of a main run of cable with a terminator at each end. All nodes like
workstations, printers, laptops servers etc., are connected to the linear
cable. The terminator is used to absorb the signal when the signal reaches the
end, preventing signal bounce. When using bus topology, when a computer sends out
a signal, the signal travels the cable length in both directions from the
sending computer. When the signal reaches the end of the cable length, it
bounces back and returns in the direction it came from. This is known as signal
bounce. Signal bounce will create problem in network, because if another signal
is sent on the cable length at the same time, the two signals will collide.
Advantages
of Bus Topology
• Easy
to connect a computer or peripheral to a linear bus.
• Requires less cable length than a star topology.
Disadvantages
of Bus Topology
• Entire network shuts down if there is a break in the main cable.
• Terminators are required at both ends of the backbone cable.
• Difficult to identify the problem if the entire network shuts down.
• Not meant to be used as a stand-alone solution.
