Chapter 7: question 7

Consider a virtual cylinder identical to the one shown in Figure 7.12 with the following characteristics: seek time is 4 ms/track, search time is 1.7 ms/sector, and data transfer time is 0.9 ms. Calculate the resulting seek time, search time, data transfer time, and total time for the following Request List, assuming that the read/write head begins at Track 3, Sector 0. Calculate the total time required.
