Memory Allocation a) Is it possible to have both internal and external fragmentation with fixed partition memory allocation? How about with dynamic/variable memory partition allocation? Explain. (1 point) b) Suppose we have 1000K of memory where the first 100K is reserved. Also suppose that the following processes have been allocated memory in the following order: P1: 100K, P2: 100K, P3: 25K, P4: 200K, P5: 200K, P6: 75K, P7: 100K. Create a diagram of memory. Suppose that P2, P4, and P6...

Given free memory blocks of A(500 KB), B(600 KB) and C(300 KB) [in order, as shown in the figure below], how would best-fit place processes of P1(160 KB), P2(500 KB), P3(132 KB) and P4(202 KB) (in order)? You may use the figures below to denote the allocation of processes into the partitions. Solution: <Write your solution here. You may use the figures below to denote allocation of processes into the partitions.> Best fit A (500 KB) B (600 KB) C(300...
