Detailed explanation-1: -Memory management strives to optimize memory usage so the CPU can efficiently access the instructions and data it needs to execute the various processes. Diagram illustrates how primary, secondary and cache memory relate to one other in terms of size and speed.
Detailed explanation-2: -The purpose of memory management is to optimize the use of a computer or device’s internal memory, that is, RAM. RAM (random access memory) consists of one or more chips on the motherboard that hold items such as data and instructions while the processor interprets and executes them.
Detailed explanation-3: -Paging, and swapping, segmentation and compaction are modern computers’ four main memory management techniques. Swapping is the best technique for memory management because it provides the most efficient use of system resources.
Detailed explanation-4: -Memory Optimization optimizes the physical memory usage of running processes on computers in your environment. With Memory Optimization enabled, Workspace Control automatically releases: reserved physical memory that is no longer used by a recently launched application.
Detailed explanation-5: -Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free. It checks how much memory is to be allocated to processes. It decides which process will get memory at what time.
