Jul 12, 2025 · In this article, we will look into the SCAN (Elevator) algorithm in detail along with the code, its implementation, etc. What is SCAN (Elevator) Disk Scheduling Algorithm?

The elevator algorithm, or SCAN, is a disk - scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests.

Mar 18, 2024 · In this tutorial, we’ll discuss the SCAN disk scheduling algorithm. We will delve into the principles and operation of SCAN, its advantages and disadvantages, and provide examples for a …

The disk scheduling algorithms are used to determine the order in which input and output (I/O) requests of the disk are to be processed. In this chapter, we will discuss the SCAN and C-SCAN disk …

Mar 17, 2025 · In various algorithms designed to reduce the discovery of discs, scans and C-scans are two popular strategies. The purpose of both is to improve efficiency by organizing how the disc arm …

Oct 15, 2024 · In SCAN, the disk arm moves from one end of the disk to the other, servicing requests along the way. Once it reaches the end, it reverses direction and continues servicing any remaining …

Circular Scan (C-SCAN) Circular scanning works just like the elevator to some extent. It begins its scan toward the nearest end and works it way all the way to the end of the system. Once it hits the bottom …

Jun 15, 2025 · The SCAN algorithm, also known as the Elevator Algorithm, is a disk scheduling algorithm used to manage the order in which disk I/O requests are serviced. It is designed to …

Sep 7, 2024 · One of the most popular disk scheduling algorithms is SCAN, also known as the Elevator Algorithm. Let’s explore how this algorithm works and why it's widely used.

Scan is often called Elevator Scheduling Algorithm, due to the way it works. In SCAN, disk arm starts from one end of the disk and executes all the requests in its way till it reaches the other end.
