Final answer:
Multiprogramming without swapping involves partitioning memory into fixed sizes where each partition contains one process, and no processes are moved in and out of memory dynamically.
Step-by-step explanation:
Multiprogramming without swapping typically refers to a scenario where programs are loaded into memory partitioned by fixed boundaries. In this context, the best match for the concept would be partitioning. The partitioning method involves dividing physical memory into fixed sizes of partitions where each partition may contain exactly one process. As a result, there are a set number of programs that can be in memory at one time, and this number does not change dynamically as it would with swapping or paging techniques where processes are moved in and out of memory. Instead, once the memory is full, the system must wait until a process completes and frees up space before another process can be loaded.
Swapping refers to the process where entire processes are moved in and out of memory to the hard disk, allowing for multiprogramming with a variable number of processes, a larger degree of concurrency and better utilization of memory. Without swapping, the number of processes is fixed according to the number of partitions available.
