Memory Management: Memory management is a critical function of an operating system that manages primary memory. It keeps track of each byte in a computer's memory and whether it is allocated to a process or it is free. It decides which processes are to be loaded into memory when and in which memory areas.

Swapping: Swapping is a method of memory management where a process can be swapped temporarily out of main memory (or move) to secondary storage (disk) and make that memory available to other processes. At a later time, the system swaps back the process from the secondary storage to main memory.

Single Partition Allocation: In single partition allocation, the operating system resides in the main memory at all times. The rest of the memory is used for user processes. The operating system uses a memory management scheme to track which parts of memory are currently being used and by whom.

Multiple Partition Allocation: In multiple partition allocation, the memory is divided into several fixed-size partitions. Each partition can contain exactly one process. In this scheme, when a process arrives, it is allocated to a partition. If all partitions are full, the operating system can swap a process out of a partition.

Multiprogramming with Fixed Partition: In multiprogramming with a fixed partition, the main memory is divided into a number of static partitions at system generation time. A process of less or equal size to the partition is selected from the input queue and is loaded into a partition. If the process is smaller than the partition, the remainder of the partition becomes an internal hole.
