Question: Define computer bus and discuss different types of computer buses.

Computer Bus:

Computer buses are fine conducting wires used to carry electrical signals between two units in a computer system.

Computer buses are three types such as:

(1) Data Bus
(2) Address Bus
(3) Control Bus

 

Data Bus:

Data buses are 8, 16, 32, 64, or 128 parallel lines used to carry data signal between two units in a computer system. Data buses are bidirectional lines.

Address Bus:

Address buses are 16, 32, 64, 128, or 256 parallel lines used to carry address signal between processor and other units in a computer system. Address buses are unidirectional lines.

Control Bus:

Control bus is a single line used to carry control signal between processor and other units in a computer system. control bus is unidirectional lines. The possible control signals are MEMR, MEMW, IOR, and IOW.
