It is also known as a Virtual address. Logical address space can be defined as the size of the process. Logical Address space: An address generated by the CPU is known as “Logical Address”. Now we are discussing the concept of logical address space and Physical address space: Logical and Physical Address Space: To maintain data integrity while executing of process.To keep track of used memory space by processes.Allocate and de-allocate memory before and after process execution.The main aim of memory management is to achieve efficient utilization of memory. Memory management is a method in the operating system to manage operations between main memory and disk during process execution. The task of subdividing the memory among different processes is called memory management.
In a multiprogramming computer, the operating system resides in a part of memory and the rest is used by multiple processes.
