Disk, seek time, latency, sector, request
Single-platter disk rotation speed: 7200 rpm number of tracks on one side of platter: 30,000 number of sectors per track: 600 seek time: 1 ms for every 100 tracks traversed Disk receives a request to access a random sector on a random track. assume the head starts at track 0.
a. What is the average seek time?b. ave. rotational latency?c. transfer time for a sector?d. total ave. time to satisfy a request?
What does fragmented mean in reference to hard drives, and what, if anything, should be done to prevent it. Describe the general path data takes in an application from user input to the computer hardware.
Other user user threads belonging to the same process also be affected by the page fault (i.e., would they also have to wait for the faulting page to be brought into memory?) Explain.
What (if any) relation holds between the following pairs of sets of algorithms (a) Priority and SJF (b) Multilevel feedback queues and FCFS

How many page faults are generated by the following arrayinitialization loops, using LRU replacement, and assuming page frame 1 has the process in it, and the other two are initially empty.
Give a solution using Monitor that is starvation-free. What would be value of semaphore before entering into Critical Section and after leaving it.
What is minimum number of page faults for the optimal page replacement strategy? Please show how the page is placed and how page faults occur.
When a process first start execution, how would you characterize the page fault rate? Once the working set for a process is loaded into memory, how would you characterize the page fault rate?
