There are three types of buses:

Address bus - Carries memory addresses from the processor to other components such as primary storage and input/output devices and is unidirectional.

Data bus - Carries the data between the processor and other components and is bidirectional.

Control bus - Carries control signals from the processor to other components. The control bus carries the clock's pulses and is unidirectional.
