The term input/output, or just I/O, generally refers to communication between the microprocessor/memory component of a PC and a peripheral component, such as a hard disk, floppy disk, monitor, keyboard, modem, printer and so on. The purpose of this chapter is to give an overview of this I/O process, speaking both in general terms and giving a few specific examples. However, it is important to keep in mind that, while there are many general procedures for I/O, the specifics can vary considerably from device to device. The best we can hope for is to gain a general understanding of the principles of the input/output operation.
