For a magnetic disk with concentric circular tracks, the seek latency is not linearly proportional to the seek distance due to

1. non-uniform distribution of requests
2. arm starting or stopping inertia
3. higher capacity of tracks on the periphery of the platter
4. use of uniform arm scheduling policies

Consider a disk system with $100$ cylinders. The requests to access the cylinders occur in the following sequences: $4, 34, 10, 7, 19, 73, 2, 15, 6, 20$ Assuming that the head is currently at cylinder $50$, what is the time taken to satisfy all requests if it takes $1$ ms to move from the cylinder to adjacent one and the shortest seek time first policy is used? $357$ ms $238$ ms $276$ ms $119$ ms
Consider that a process has been allocated $3$ frames and has a sequence of page referencing as $1, 2, 1, 3, 7, 4, 5, 6, 3, 1$. What shall be the difference in page faults for the above string using the algorithms of LRU and optimal page replacement for referencing the string? $2$ $0$ $1$ $3$
