Explanation

A bus is a high-speed internal connection that sends data and control signals between the processor and other components.

The amount of data a data bus can transfer is known as bandwidth. 

1. Data bus: A bidirectional communication path that transfers data between the CPU, memory, and input/output devices.
2. Address bus: Transmits the physical location (address) of data to be accessed or written by the CPU.
3. Control bus: Transfers control signals for coordinating the overall system's operation.
