4. 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: Job Number Memory Block List: Memory Block Memory Block Size Memory Requested Job A 9ook Block 1 990K Block 2 96ok Job B Job C 275K 760K Block 3 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
