What is CPU scheduling explain the different scheduling algorithm?

CPU scheduling is a process of determining which process will own CPU for execution while another process is on hold. In Preemptive Scheduling, the tasks are mostly assigned with their priorities. In the Non-preemptive scheduling method, the CPU has been allocated to a specific process.

What are different types of scheduling algorithm?

Operating System Scheduling algorithms

• First-Come, First-Served (FCFS) Scheduling.
• Shortest-Job-Next (SJN) Scheduling.
• Priority Scheduling.
• Shortest Remaining Time.
• Round Robin(RR) Scheduling.
• Multiple-Level Queues Scheduling.

Which of the following scheduling algorithms is preemptive scheduling *?

Algorithms based on preemptive scheduling are: Round Robin (RR),Shortest Remaining Time First (SRTF), Priority (preemptive version), etc. 2.

What is the difference between preemptive and non-preemptive scheduling algorithm?

In preemptive scheduling, the CPU is allocated to the processes for a limited time whereas, in Non-preemptive scheduling, the CPU is allocated to the process till it terminates or switches to the waiting state.

What is process scheduling algorithm?

Scheduling Algorithms. A scheduling algorithm is the algorithm which dictates how much CPU time is allocated to Processes and Threads. The goal of any scheduling algorithm is to fulfill a number of criteria: no task must be starved of resources – all tasks must get their chance at CPU time;

What is CPU scheduling?

CPU scheduling is a process which allows one process to use the CPU while the execution of another process is on hold(in waiting state) due to unavailability of any resource like I/O etc, thereby making full use of CPU. The aim of CPU scheduling is to make the system efficient, fast and fair.

What is a disk scheduling algorithm?

The SCAN algorithm is a disk scheduling algorithm that helps in determining the motion of a disk’s arm and head in executing the read and write requests. In the SCAN scheduling algorithm, the disk arm moves in a single direction and executes all the jobs coming in its way.

What is operating system scheduling?

Operating system scheduling is the process of controlling and prioritizing messages sent to a processor.
