University of Mumbai
Time: 2 hour 30 minutes Max. Marks: 80
compulsory and carry equal marks
3. Suppose process is in “Blocked” state waiting for some I/O service. When
Option B: | PCB is created per process which is used to store relevant information about
Resource request is done in particular
toward the other end, servicing requests till the other end of the disk. At the other
end, the direction is reversed and servicing continues
Run time mapping from virtual to physical address is done
the above process being scheduled with the SJF scheduling algorithm, which of
the following statement is true?
A sizes 400,180, 100,300,45. Assuming First fit and Best fit method indicate the
memory status after memory request for sizes 95, 180, 285, 380, 30
Consider the page reference string 1,2,3,5,2,4,5,6,2,1,2,3,7,6,3,2,1,2,3,6
memory with three frames
Differentiate between process
Explain about file attributes, file operations, and file types
Suppose the head of a moving disk with 200 tracks, numbered 0 to 199, is
Currently serving a request at track 143 and has just finished a request at track
A the queue of requests is kept in FIFO order: 86, 147,91, 177, 94, 150, 102,
175, 130. What is the total head movement to satisfy these requests for the
following Disk scheduling algorithms. (a)FCFS (b)SSTF (c) C- SCAN
Consider the following five processes, with the length of the CPU burst time
given in milliseconds. Process Burst time is P1-10, P2-29, P3-3, P4-7,P5-12
Consider the First come First serve (FCFS), Non Preemptive Shortest Job
the scheduling using Gantt chart. Calculate the Average Waiting Time and Turn
Dining philosopher is solved using semaphores?
