QUESTIONS (CLO 3) Consider the situation in which the disk read/write (R/W) head is currently located at track 50.the disk contains 200 tracks. Assume that the following track requests have been made in this order: 95, 180, 34, 119, 11, 123, 62, 64 Question: Compute the average seek length for the request sequence given above using the SCAN and LOOK algorithms (down). Note: the SCAN algorithm is performed by moving the R/W head back-and-forth to the innermost and outermost track. As it scans the tracks from end to end, it processes all the requests found in the direction it is headed. LOOK algorithm is similar to SCAN algorithm except for the end-to-end reach of each sweep. The R/W head is only tasked to go the farthest location in need of servicing
