Of course, the requirements for each device are different: there are multiple devices attempting to do i/o at the same time. It would tie up too much time to use the cpu to provide that control. Mgmt 1040 tutorial 2 notes programmed i/o. I/o modules that control a single type of device are often called device controllers: for example, an i/o module that controls disks would be a disk controller, we look at the i/o modules more carefully.
