Differentiate between a logical address and a physical address in computer memory management. b. Explain the role of the base register and limit register in address translation. [2 marks] An operating system needs to load four (4) jobs into memory. The memory blocks [2 marks] available are Block 1-800 KB, Block 2-910 KB, Block 3-200 KB, Block 4-60 KB., Block 5-55 KB. Each program and its memory requirements are shown in Table 2. c. ii. Job A B C D Memory needed 57 KB 920 KB 50 KB 701 KB Table 2: Memory requirements for processes. With the aid of a diagram each, indicate how each of the four jobs will be allocated memory using first fit, best fit, worst fit and next fit allocation algorithms. [4 marks] Calculate the total internal fragmentation for any three (3) of the allocation algorithms. [3 marks] Calculate the total external fragmentation for the three (3) allocation algorithms you chose in ii. [3 marks] d. A 32-bit computer uses 2 KB page sizes. How many bits are used to represent the page number and the offset? If a program of size 72,766 Bytes needs to be loaded into memory, how many pages will it require and what is the total internal fragmentation?
