Detailed explanation-1: -An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.
Detailed explanation-2: -Address bus-carries memory addresses from the processor to other components such as primary storage and input/output devices. The address bus is unidirectional . Data bus-carries the data between the processor and other components. The data bus is bidirectional .
Detailed explanation-3: -A data bus can transfer data to and from the memory of a computer, or into or out of the central processing unit (CPU) that acts as the device’s “engine.” A data bus can also transfer information between two computers.
Detailed explanation-4: -An individual bus permits communication between devices using one data channel. The control bus is bidirectional and assists the CPU in synchronizing control signals to internal devices and external components. It is comprised of interrupt lines, byte enable lines, read/write signals and status lines.
