A buddy system allocates memory from a fixed-size segment consisting of physically contiguous pages using power-of-2 allocator. Consider computer system that has 1024M memory available. Figure 3 shows the initial state of the memory and the lists of memory requests. Memory requests: 1024 Process Size: А: 115MB В: 228MB С: 365MB D: 54MB Request A Request B Release A Request C Request D Release C Main memory a. Based on Figure 3, show the results of each memory request'release using buddy system. b. Calculate the total of internal fragmentation (in M unit) after C has been released.
