. Given the following: configuration with jobs arriving in order (Job A, B, and C) and with blocks shown in order from low-order memory to high-order memory: Job List: Memory Block List: Job Number Memory Requested Memory Block Memory Block Size Job A 990K Block 1 900K Job B 275K Block 2 960K Job C 760K Block 3 300K Job List: Memory Block List: Job Number Memory Requested Memory Block Memory Block Size Job A 256K Block 1 910K Job B 900K Block 2 900K Job C 50K Block 3 200K Job D 350K Block 4 300K a. Use the first-fit algorithm to indicate which memory blocks are allocated to each of the arriving jobs. b. Use the best-fit algorithm to indicate which memory blocks are allocated to each of the arriving jobs. c. Calculate the amount of internal fragmentation in Block 1 using the first-fit algorithm.
