It is like to the SCAN disk scheduling algorithm but the change that the disk arm in spite of going to the end of the disk goes only to the last demand to be checked in front of the head and then backs its direction from there only. Therefore, it avoids the additional postponement ...
SCAN scheduling algorithm is also called the elevator algorithm because in such kind of algorithm arm behaves just like an elevator for building the way. In the SCAN algorithm, the arm will start at the one end of the disk and then move towards another end of the disk. At the last end,...

This article examines the problem of disk scheduling in a multimedia I/O system. In a multimedia server, the disk requests may have constant data rate requirements and need guaranteed service. We propose a new scheduling algorithm, SCAN-EDF, that combines the features of SCAN type of seek ...

Disk scheduling is responsibility of operating system. To achieve this, it is required that disk drives should have fast access time and bandwidth. To improve both access time and bandwidth we need to schedule the servicing of disk I/O Request in efficient way. There are various Algorithm propo...
In subject area: Computer Science A Disk Controller is a component responsible for interfacing the computer system with the hard drive. It converts operating system requests into instructions for the hard drive and manages the flow of data to and from the drive. ...
