1. e-mail address. 2. Internet address. 3. MAC address. 4. An unsigned integer used to select one fundamental element of storage, usually known as a word from a computer' s main memory or other storage device. The CPUoutputs addresses on its address bus which may be connected to an address decoder, cache controller, {memory management unit}, and other devices. While from a hardware point of view an address is indeed an integer most strongly typed programming languages disallow mixing integers and addresses, and indeed addresses of different data types. This is a fine example for {syntactic salt}: the compiler could work without it but makes writing bad programs more difficult. (1997-07-01)
