  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.
