COMPUTER FUNDAMENTALS

Detailed explanation-1: -Memory management is the process of controlling and coordinating a computer’s main memory. It ensures that blocks of memory space are properly managed and allocated so the operating system (OS), applications and other running processes have the memory they need to carry out their operations.

Detailed explanation-2: -The Memory Manager manages memory in the system and is responsible for allocation and deallocation of memory, virtual memory management, etc. The File Manager manages the file system, and keeps track of directories, files, and related information.

Detailed explanation-3: -A memory management unit (MMU) is a computer hardware component that handles all memory and caching operations associated with the processor. In other words, the MMU is responsible for all aspects of memory management.

Detailed explanation-4: -(1) To keep track of all memory locations free or allocated and if allocated, to which process and how much. (2) To decide memory allocation policy i.e., which process should get how much memory when and where. (3) To use various techniques and algorithms to allocate or deallocate memory locations.

Detailed explanation-5: -The Operating System is responsible for the following activities in connection with memory management: Keeping track of which portion of memory are currently being used and who is using them. Determining which processes (or parts of processes) and data to move in and out of memory.
