Absolute address can be different things. One of which is simply a fixed location in the computer’s memory. It can be the explicit identification of a memory location, a peripheral device, or a location within a device.

This is also a term used in spreadsheet programs. An absolute address is a cell address that refers to a fixed location that will not change when a formula is copied to another location. In many spreadsheet programs, such as Excel and Lotus 1-2-3, the absolute address is indicated by placing a dollar sign before the column and row indicator.
