WebContiguous memory allocation contains two memory allocations: single partition and multi-partition. It contains Paging and Segmentation. The memory space is partitioned … WebFixed partitions memory is divided into several regions of fixed size. Generally, a process runs in a partition that is the best fit to its memory needs, though some internal fragmentation is almost always involved. An example is IBM MFT (Multiprogramming with a Fixed number of Tasks) which was part of OS/360.
