Data Bus : The data bus like the address bus consists of parallel signal lines connected to the cpu, the main memory and the I/O port.That the data bus part of the overall computer bus,help to transfer data from one device to another.
Control Bus : Many devices are joined to the control bus.It helps to transfer control from one instruction to another during program running.It also transfers control signals to various devices.
Address Bus : The address bus consists of parallel signal lines joined to the central processing unit, the main memory and the I/O ports.The bus that helps to locate the address of data in memory is called address bus.It is also used to locate the memory address of instructions to be executed.
