Absolute addressing is a method used in computer programming and assembly language where the exact memory location of data or instructions is specified. This means that the address is fixed and does not change, allowing the program to directly access the required data in memory. In contrast to relative addressing, which calculates addresses based on the current position in the code, absolute addressing provides a straightforward way to reference specific locations. This technique is commonly used in low-level programming, such as with assembly language and machine code, where precise control over memory is essential.
