Question
![An application loads '1000' libraries at startup. Loading each library
takes exactly one magnetic disk access. Let the seek time of the disk to a
random location is 12 milliseconds and disk is operated at 100 RPS
(Revolutions per second). If all 1000 libraries are loaded from random
locations on the disk, how long does it take to load all libraries?
Note: (The time to transfer data from the disk block once the head has
been positioned at start of the block may be neglected).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9c4ba9e0-07ae-4205-8e37-8db72aacf99b%2F5447eae6-b5d4-4545-8ebb-0f2d8aaf0415%2Fivmii6_processed.jpeg&w=3840&q=75)
