Input and output devices are connected to CPU by a number of cables or lines. These lines are called buses in computer terminology. Bus is a communication system that transfers data between components in a computer system. There are basically 3 types of buses namely; address bus, data bus and control bus. The address bus carries the address of memory or I/O device that is required by CPU. This bus is also called A bus. The data bus is used to transfer data between processors, memory and I/O devices.
