address (redirected from computer address)

(1) The number of a particular memory or peripheral storage location. Like post office boxes, each byte of memory and each disk sector has its own unique address. Programs are compiled into machine language, which references actual addresses in the computer.

(2) As a verb, to manage or work with. For example, "the computer can address 16MB of memory."

(3) The location of a Web site or other Internet facility. See URL.

1.	(networking)	address - e-mail address.
2.	(networking)	address - IP address.
3.	(networking)	address - MAC address.
4.	(storage, programming)	address - 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 CPU outputs 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.
