19 Questions
What is the purpose of the CPU scheduler?
To allocate CPU cores to processes in the ready queue
Which of the following situations does NOT require a CPU scheduling decision?
A process switches from running to waiting state
How can the ready queue be ordered?
The text does not specify how the ready queue can be ordered
In which situation(s) does the CPU scheduler have a choice regarding which process to execute?
Both B and C
What is the primary function of the CPU scheduler?
To manage the execution of processes on CPU cores
In which of the following CPU scheduling decision points does the scheduler have a choice regarding which process to execute?
When a process switches from running to ready state
Which of the following is the best description of the primary function of the CPU scheduler based on the information provided?
To allocate CPU cores to processes in the ready queue
What is a key advantage of nonpreemptive scheduling in terms of system behavior?
Reduced overhead costs
Why does nonpreemptive scheduling lack flexibility compared to preemptive scheduling?
Inability to adapt to changing conditions dynamically
What is a significant disadvantage of nonpreemptive scheduling in terms of multitasking?
Lack of multitasking ability
Why might nonpreemptive scheduling struggle to meet deadlines in real-time systems?
Long-running tasks may prevent timely execution of critical tasks
In which type of system application is nonpreemptive scheduling commonly used due to the need for high efficiency and deterministic behavior?
Embedded Systems
What characteristic distinguishes nonpreemptive scheduling in batch processing applications?
Execution without interruption for efficient resource use
What is the key distinction between nonpreemptive and preemptive scheduling?
Preemptive scheduling allows tasks to be interrupted, while nonpreemptive scheduling does not.
What is the main principle behind nonpreemptive scheduling?
Efficient use of resources
Which of the following is a disadvantage of nonpreemptive scheduling?
It is less flexible than preemptive scheduling.
Which of the following is a key advantage of nonpreemptive scheduling?
It allows for better resource utilization.
Why is nonpreemptive scheduling suitable for systems that require exclusive access to certain hardware components or software modules?
Because it does not allow for sharing of resources among tasks.
Which of the following best describes the flexibility of nonpreemptive scheduling compared to preemptive scheduling?
Nonpreemptive scheduling is less flexible as it cannot adapt to changing conditions dynamically.
Test your knowledge on how the CPU scheduler selects processes in the ready queue and allocates a CPU core based on different scenarios such as process state transitions and terminations.
