Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

c) Suppose a disk has 300 cylinders, numbered from 0 to 299. The drive is currently serving an I/O request at cylinder 111 and the disk head was previously serving a request at cylinder 99, and there is a queue of disk access requests for cylinders as below: 181, 199, 150, 160, 85, 178, 109, 75 Starting from the current head position, calculate the total head movements using the following disk scheduling algorithms.(i) SSTF scheduling (ii) SCAN scheduling
