Disk Arm Scheduling AlgorithmsIn this tutorial, there are three main algorithms that control how the disk arm on a hard disk reads data. These three algo..
The disk scheduling algorithms aim to optimize the use of the hard disk by reducing the seek time and rotational latency, which ultimately results in improved performance and efficiency of the system. In this tutorial, we’ll discuss two disk scheduling algorithms – LOOK and CLOOK – and compar...
This algorithm is also called the elevator algorithm because of it's behavior. Here, first the head moves in a direction (say backward) and covers all the requests in the path. Then it moves in the opposite direction and covers the remaining requests in the path. This behavior is similar ...

OS | Disk Scheduling Algorithms: In this tutorial, we will learn about the various disk scheduling algorithms along with its advantages and disadvantages.
Selection of a Disk Scheduling Algorithms SSTF is a common algorithm which will increase the performance over the FCFS. SCAN and C-SCAN perform better for the system which places a heavy load on the disk because there is no such kind of a starvation problem. For any kind of the algorithm,...
I added five disk scheduling algorithms and test classes to the disk scheduling folder, and they adopted different strategies when simulating disk read and write requests. They are SSF, SCAN, CSCAN, LOOK and CLOOK algorithms. SSF (shortest seek first) algorithm is a disk scheduling strategy, an...
A continuum of disk scheduling algorithms, V(R), having endpoints V(0) = SSTF and V(1) = SCAN, is defined. V(R) maintains a current SCAN direction (in or out) and services next the request with the smallest effective distance. The effective distance of a request that lies in the cu...
