BUS

      A bus network consists of a single central cable (backbone/trunk) to which all computers and other devices connect (node)

      * The bus is the physical cable that connects the computers and other devices 

* Each devices is connected to the single bus cable through T-connector 

* A terminator is required at each end of the bus cable to prevent the signal from bouncing back and forth on the bus cable

      
How the data transmit:

In a bus network, it transmit
data, instructions and receiving device is included) as a series of
signal in both directions where all nodes receive the signal but only
the intended recipient will accept the signal and the rest will ignore

Advantages of Bus Topology	Disadvantages of Bus Topology
Failure of one device usually does not affect the rest of the bus network	The network will e malfunctioned if the single central cable breaks down
Bus networks are inexpensive and easy to install	A break in the backbone (single central cable) will prevent all systems from accessing the network
Computers and other devices can be attached and detached at any point without disturbing the rest of the network	If more computers are connected, the performance of the network will become slower because of data collision
