What is Address Bus, Data Bus and Control Bus in Microprocessor 8051 ?

Address Bus in a microprocessor can be defined as a computer bus architecture. It is a group of wires that are utilized to transfer the addresses of the I/O devices or Memory and is unidirectional. In the 8081 microprocessor in Intel, the Address Bus was of 16 bits.

This meant that the Microprocessor 8081 could maximum transfer up to a maximum of 16-bit addresses. The address is then deposited in the form of binary numbers so that the data bus can get access the memory storage.
