Base addressing is a method used in computer memory management where a base address is defined as a reference point for accessing data. This base address is typically stored in a register, allowing the system to calculate the actual memory location by adding an offset to the base address. This technique simplifies memory access and enables efficient use of memory space. In base addressing, the offset represents the distance from the base address to the desired data location. This approach is commonly used in programming languages and operating systems, facilitating easier data manipulation and organization. It is particularly useful in managing arrays and dynamic memory allocation.
