Input / Output (I/O) Addresses
Input/output addresses (usually called I/O addresses for short) are resources used by virtually every device in the computer. Conceptually, they are very simple; they represent locations in memory that are designated for use by various devices to exchange information between themselves and the rest of the PC.
Note: I/O addresses are
referred to in hexadecimal notation. See
