The _____ provides a path between the CPU and peripheral devices, which are connected via interface cards.

A computer
B expansion bus
C memory
D CPU
E None of the above

Correct Answer: expansion bus

The expansion bus provides a path between the CPU and peripheral devices, which are connected via interface cards. Peripherals are any of the many external devices that connect to your computer. Obviously, the processor must have some way of talking to the peripherals to make them useful. The communication channel between the processor and the peripherals is called a bus.
