What is bus in microprocessor?

The Bus is common terms in the microprocessor which is mostly used for transmission. The system of the bus is to transmit the data/information and address in binary form.

The bus is a collection of wires that means one wire per binary bit. In microprocessor have three types of the bus which is following.

1. Address Bus: This is the unidirectional bus which is transmitting the address in binary form. The bus transmits data from the microprocessor to memory or input/output devices.
2. Data Bus: The data bus is bidirectional and carries the data and information. This data flow both direction which means from memory/devices to microprocessor and from microprocessor to memory or input/output devices
3. Control Bus: This is used to control the signal and other peripherals to flow data and transfer to the required memory location.
