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. WebC-SCAN Disk Scheduling Algorithm-. Circular-SCAN Algorithm is an improved version of the SCAN Algorithm. Head starts from one end of the disk and move towards the other end servicing all the requests in between. After reaching the other end, head reverses its direction. It then returns to the starting end without servicing any request in between.
