Operating systems are known to mediate between hardware and users of a system. There are many types of operating systems currently in use. In all systems, memory plays a key roll in using the system. a. Draw a structure of the storage hierarchy and how its various components relate to: i. Speed ii. Cost iii. Volatility iv. Size b. Explain why a computer that uses DMA should be a preferred choice over those that do not use DMA. c. Draw the structure of a computer system. d. If you handle a lot of data, explain how you would protect your data.

Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free. Given five memory partitions of 110 KB, 450 KB, 100 KB, 250 KB, and 500 KB (in order), how would each of the first-fit, best-fit, and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)?Which algorithm makes the most efficient use of memory? Write a program to compare and justify your answer. C language.
