8: Memory Management 4 MEMORY MANAGEMENT • The concept of a logical address space that is bound to a separate physical address space is central to proper memory management. • Logical address – generated by the CPU; also referred to as virtual address • Physical address – address seen by the memory unit • Logical and physical addresses are the same in compile-time and load-

Memory Management Main memory is a very important component in a computer system because both the oper-ating system and various user applications have to be loaded into main memory first before being able to be executed. The efficiency of memory management to much extent affects the efficiency of the whole system.
