NETWORK TOPOLOGY
DEFINITION/ PHYSICAL TOPOLOGY OF BUS NETWORK
- A bus network consists a single central cable (backbone/trunk), to which all computers and other devices connect (node).
- 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.
LOGICAL TOPOLOGY / HOW DATA TRANSMIT :
In a bus network, it transmit data, instructions and information (the
address of the 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 :
- Failure of one device usually does not affect the rest of the bus network.
- Bus networks are inexpensive and easy to install
DISADVANTAGES :
- The network will be malfunctioned if the single central cable break down.
- It is difficult to identify the problem if the entire network shut down.
