In a 1,024-KB segment, memory is allocated using the buddy system. Using Figure 8.26 as a guide, draw a tree illustrating how the following memory requests are allocated: Request 6-KB Request 250 bytes Request 900 bytes Request 1,500 bytes Request 7-KB Next, modify the tree for the following releases of memory. Perform coalescing whenever possible: Release 250 bytes Release 900 bytes Release 1,500 bytes In a 1,024-KB segment, memory is allocated using the buddy system.
