To transport data between memory and I/O devices, the computer system's CPU interfaces with them. However, the CPU communicates with memory and I/O devices in distinct ways. Either directly or through the Cache memory, the CPU can connect with the memory. The communication between the CPU and the I/O devices, on the other hand, is normally accomplished through the use of an interface.
