Final answer:
A common set of wires used for communication between devices and the computer system is known as a bus. It connects different components and facilitates data transfer.
Step-by-step explanation:
If one or more devices use a common set of wires to communicate with the computer system, the connection is called a bus. The term bus in computer architecture refers to the system that connects the various parts of a computer system, such as the CPU, memory, and peripheral devices.
