BUS NETWORK

Definition/Physical topology of bus network	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.
Logical topology of bus network/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. Computers and other devices can be attached and detached at any point on the bus without disturbing the rest of the network.
Disadvantages	The network will be malfunctioned if the backbone (single central cable) breaks down. As more PC are connected the performance of the hardware will become slower because of data collisions.
