16 Questions
What is the role of the short-term scheduler (CPU scheduler)?
Selecting the next process to execute based on priorities
What is the role of the dispatcher in the context of scheduling?
Preparing the chosen process for execution and starting it
What is the function of the priority function in scheduling?
Determines the current priority of a process given its parameters and system state
What is the decision mode involved in scheduling to 'break ties' when priority functions yield the same value for multiple processes?
Arbitration rule
In which scheme does a process execution continue until it 'voluntarily' gives up the processor by termination or blocking?
Nonpreemptive scheme
What is the role of the preemptive scheme in scheduling?
Allows stopping a process's execution to allocate CPU to a higher (or equal) priority process
Which component of priority classifies processes with respect to their importance or 'niceness'?
External priority
What is the time interval allocated to a process that has passed called?
Waited time
In systems with dynamic priorities, what is possible with regards to process priority in ready state?
Increase in another process priority above the priority of the process currently executed
What is the percentage of time with CPU allocated to a process known as?
Processor utilization
What is the total time from admission (attained service + waited + resource request service time) referred to as?
Real time in system
Which of these represents a non-preemptive scheduling algorithm?
LCFS
What does SJF stand for in non-preemptive scheduling algorithms?
Shortest Job First
Which parameter does the priority function use that represents the time before which the process must finish execution in real-time systems?
Time to deadline
In non-preemptive scheduling algorithms, which ability refers to task execution time not drastically increasing with system load, from the user's point of view?
Predictability
What does FCFS stand for in non-preemptive scheduling algorithms?
