11 Questions
What is the primary goal of CPU scheduling in a multi-programming environment?
To keep the CPU as busy as possible.
Which CPU scheduling algorithm is non-preemptive and selects the next process to run based on arrival time?
First-Come, First-Served
In the Linux Completely Fair Scheduler, how is the time quantum for a process determined?
Based on the nice value of the process.
What is the purpose of processor affinity in multiprocessor scheduling?
To keep a process running on the same processor to increase efficiency.
What is the main disadvantage of the First-Come, First-Served (FCFS) scheduling algorithm?
It can lead to the convoy effect
How does the Shortest-Job-First (SJF) scheduling algorithm determine which process to run next?
By the length of the next CPU burst
What is a primary concern with Priority Scheduling?
The possibility of starvation
What is Round-Robin Scheduling particularly good at improving?
Response time for time-sharing systems
What is the effect of setting a high 'nice' value for a process in Linux?
It gives the process lower priority.
What scheduling scope would likely be used for kernel-level threads?
System-Contention Scope (SCS)
