WebApr 25, 2024 · SCAN SCHEDULING. In this algorithm, the disk arm works like an elevator starting at one end servicing all the way up to the other end and then start from the other end in reverse order.To use the SCAN … WebThe disk head moves from one end of the disk to the other performing I/O as the head passes the desired cylinder; then reversing directions at the end. Circular SCAN (C-SCAN) Scheduling Does the same as the SCAN algorithm except when it reaches the end, it goes right back to the beginning without servicing any requests.
WebNov 7, 2024 · Overhead. 3. SCAN. In SCAN algorithm the disk arm travels into a specific way and facilities the requests approaching in its path and after reaching the end of the disk, it converses its direction and again services the request incoming in its path. So, this algorithm works like an elevator and hence also recognized as elevator algorithm. Web18 Selecting a Disk-Scheduling Algorithm SSTF is common and has a natural appeal SCAN and C-SCAN perform better for systems that place a heavy load on the disk. Performance depends on the number and types of requests. Requests for disk service can be influenced by the file- allocation method. The disk-scheduling algorithm should be …
