(1) A location of data, usually in main memory or on a disk. You can think of computer memory as an array of storage boxes, each of which is one byte in length. Each box has an address (a unique number) assigned to it. By specifying a memory address, programmers can access a particular byte of data. Disks are divided into tracks and sectors, each of which has a unique address. Usually, you do not need to worry about addresses unless you are a programmer.
(2) A name or token that identifies a network component. In local area networks (LANs), for example, every node has a unique address. On the Internet, every file has a unique address called a URL.

- Address Bus
A collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory. The width of the address bus (that is, the number of wires) determines how many unique memory locations can be addressed. Modern PCs and Macintoshes have as many as 36 address lines, which enables […]
- address space
The set of all legal addresses in memory for a given application. The address space represents the amount of memory available to a program. Interestingly, the address space can be larger than physical memory through a technique called virtual memory.
- address translation cache
Another name for a translation look-aside buffer.
- addressable resolution
In digital television the addressable resolution is the highest resolution signal that a display device (TV or monitor) can accept. A device in some circumstances may not be able to display the highest resolution it can receive.
