Question
In Operating Systems, which of the following is/are CPU scheduling algorithms?
a. Round Robin
b. Priority
c. Shortest Job First
d. All of the mentioned
Solution
d. All of the mentioned
Explanation:
a. Round Robin: This is a pre-emptive algorithm that is designed especially for time-sharing systems. It is simple, easy to use and starvation-free as all processes get fair share of CPU.
b. Priority: In this scheduling algorithm, every process is assigned a priority. The process with the highest priority is to be executed first and so on. If processes with the same priority exist, they are executed on first come first served basis.
c. Shortest Job First: This is a non-preemptive, pre-emptive scheduling algorithm. The idea is to associate with each job the length of its next CPU burst. When the CPU is available, it is assigned to the process that has the smallest next CPU burst.
So, all of the mentioned (Round Robin, Priority, Shortest Job First) are CPU scheduling algorithms in Operating Systems.
