Abstract

Every useful program has some form of output and normally an input. Figure 2.1 shows some examples of input and output devices. The input could be from a keyboard, a file, input/output ports, a mouse, and so on. Output can be sent to devices such as displays, printers, hard disks, and so on. Typically, computers can also communicate with devices such as external devices, such as lights, motors, and so on.
