WebFixed partition Memory Allocation . The simplest scheme for managing this available memory for user programs is to partition it into regions with fixed boundaries. One possibility of fixed size is to make use of equal partitions or random size of different memory partitions. In this case, any process whose size is less than or equal to the ... 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.
