Techopedia Explains Memory Management

Memory management deals with the management of a computer’s physical memory or random access memory (RAM). Typically, each computer has preinstalled main memory, which is used for processing running application and services. No matter how great memory capacity is, it cannot accommodate all ready/running programs or processes simultaneously. Thus, memory management helps allocate necessary memory space for each process, moving it in between hard drive and memory, and assigning priorities and the overall organization of the programs/processes. Memory management is usually performed and managed by the host operating system.
