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 dire
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,...
The primary goal of these algorithms is to minimize disk access time and improve overall system performance. First-Come-First-Serve The First-Come-First-Served (FCFS) disk scheduling algorithm is one of the simplest and most straightforward disk scheduling algorithms used in modern operating systems...

Along with modernization of computer, the speed of hardware (like processor, RAM, and ...
It then returns to the first request at the starting end without servicing any request in between. The same process repeats. Also Read-SCAN Disk Scheduling Algorithm Advantages- It does not causes the head to move till the ends of the disk when there are no requests to be serviced. ...
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 ...
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. ...
