10 Questions
What is the purpose of CPU Scheduling?
The purpose of CPU Scheduling is to make the system more efficient, faster, and fairer.
When does the CPU scheduler select a process from the ready queue?
The CPU scheduler selects a process from the ready queue when the CPU becomes idle.
Under what circumstances do CPU scheduling decisions take place?
CPU scheduling decisions may take place when a process switches from the running state to the waiting state (for I/O request or invocation of wait for the termination of one of the child processes), or when a process switches from the running state to the ready state.
What is the role of the temporary (CPU) scheduler in CPU scheduling?
The temporary (CPU) scheduler selects between memory processes ready to launch and assigns the CPU to one of them.
How does CPU Scheduling make full use of the CPU?
CPU Scheduling allows one process to use the CPU while another process is delayed (in standby) due to unavailability of any resources such as I/O, thus making full use of the CPU.

The temporary (CPU) scheduler selects between memory processes ready to launch and assigns the CPU to one of them whenever the CPU becomes idle.
How does CPU Scheduling contribute to system efficiency?
CPU Scheduling makes the system more efficient by allowing the operating system to select one of the processes in the line ready for launch whenever the CPU becomes idle, thus making full use of the CPU.
Study Notes
CPU Scheduling
- CPU Scheduling is the process of allocating the CPU time to different processes to maximize CPU utilization and system efficiency.
- The purpose of CPU Scheduling is to allocate the CPU time to different processes to maximize CPU utilization and system efficiency.
- CPU Scheduling decisions take place when a process:
- Switches from running to waiting/blocked state
- Switches from waiting/blocked to ready state
- Terminates
- Interrupt occurs
- The CPU scheduler selects a process from the ready queue when a process is terminated or interrupted, or when a process switches from waiting to ready state.
- The temporary (CPU) scheduler plays a role in CPU scheduling by selecting a process from the ready queue and allocating the CPU time to it.
- CPU Scheduling makes full use of the CPU by allocating the CPU time to different processes, ensuring that the CPU is always executing some process.
- CPU Scheduling contributes to system efficiency by:
- Maximizing CPU utilization
- Minimizing CPU idle time
- Improving system responsiveness
- Enhancing overall system performance
