Detailed explanation-1: -To accommodate the allocation process, the OS continuously moves processes between memory and storage devices (hard disk or SSD), while tracking each memory location and its allocation status. The OS also determines which processes will get memory resources and when those resources will be allocated.
Detailed explanation-2: -Memory management is the process of allocating memory to programs and keeping the programs in memory separate from one another. Some systems divide memory into separate areas, called partitions or regions.
Detailed explanation-3: -Memory partitioning is the system by which the memory of a computer system is divided into sections for use by the resident programs. These memory divisions are known as partitions. There are different ways in which memory can be partitioned: fixed, variable, and dynamic partitioning.
Detailed explanation-4: -Memory Management: An operating system manages the allocation and deallocation of the memory to various processes and ensures that the other process does not consume the memory allocated to one process. Device Management: There are various input and output devices.
Detailed explanation-5: -The two fundamental methods of memory allocation are static and dynamic memory allocation. The static memory allocation method assigns the memory to a process, before its execution. On the other hand, the dynamic memory allocation method assigns the memory to a process, during its execution.
