Bus

Buses or bus lines are the wires that serve as electrical roadways, transmitting information between the CPU and other components.

The size of the bus is related to the amount of data that can be transmitted at once.

Address Bus:

Transports the destination address where data needs to be processed within the computer.

Data Bus:

Transfers data back and forth between the CPU, memory unit, and input/output devices.

Control Bus:

Sends control signals (like commands from the CPU or status updates from hardware devices) throughout the system, helping manage and coordinate all the computer's operations.
