Suppose that a disk drive has 1,024 cylinders, numbered 0 to 1,023. The driver is currently serving a request at cylinder 257 and has previously serviced cylinder 156. The queue of pending requests is as follows: 94 145 715 487 655 1005 630 753 905 Starting from the current head position, what is the total distance traversed by the disk arm in satisfying all the requests using the ff. disk scheduling algorithm: FCFS, SSTF, SCAN,C-SCAN, LOOK and C-LOOK. Use chart to illustrate the head movement per algorithm.

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
