GATE CS 2022 : Operating System-1 (App update required to attempt this test)

Which of the following system use more than one CPU to execute any program?

Why a process is sent from ready to suspend Ready state?

Consider the following program:

What will be the final values of x and y after completion of the above concurrent program.
1. x = 1, y = 5
2. x = 6, y = 10
3. x = 6, y = 5
4. x = 1, y = 4

Consider the set of 3 processes whose arrival time and burst time are given below:

If the CPU scheduling policy is FCFS, calculate the idle time of the CPU.

Consider the following table

Process	P1	P2	P3	P4
Arrival Time	0	1	2	3
Service Time	6	3	1	4

Find the average turnaround time when processes are scheduled with SRTF
