Given six memory partitions of 100 MB, 170 MB, 40 MB, 205 MB, 300 MB, and 185 MB (in order). How would the first-fit, best-fit, and next-fit algorithms place processes of size 200 MB, 15 MB, 185 MB, 75 MB, 175 MB, and 80 MB (in order)? Indicate which if any requests cannot be satisfied. Comment on how efficiently each of the algorithms manages memory. In a 1,024-KB segment, memory is allocated using the buddy system. Draw a tree illustrating how the following memory requests are allocated: Request 65-KB Request 135 KB. Request 140 KB. Request 30 KB. Request 120 KB.
