Memory Allocation Strategies

If it is not desirable to move blocks of due storage from one area of memory to another, it must be possible to relocate memory blocks that have been freed dynamically. Every time a request is made for storage, a free area large sufficient to accommodate the size requested must be allocated. The most obvious methods for keeping track of the free blocks are to use linear linked list. Every free block having a field containing the size of the blocks and a field having a pointer to be next free block. A global P for free block points to the 1st free block on this list. There are various methods of selecting the free block to use at when requesting storage.
