In computing, scheduling is the action of assigning resources to perform tasks. The resources may be processors, network links or expansion cards. The tasks may be threads, processes or data flows. …

Dec 10, 2025 · This article discussed CPU scheduling concepts: arrival, burst, completion, turnaround, waiting, and response times. We also discussed how to calculate them, providing an example for …

Oct 1, 2025 · When you use a computer or mobile device, many tasks run at the same time, such as opening apps, playing music, or downloading files. The operating system manages these activities to …

To solve this problem, we will introduce a new scheduling algorithm, classically referred to as Round-Robin (RR) scheduling [K64]. The basic idea is simple: instead of running jobs to completion, RR …

In a simple system running a single process, the time spent waiting for I/O is wasted, and those CPU cycles are lost forever. A scheduling system allows one process to use the CPU while another is …

Dec 2, 2025 · Process scheduling is the activity of the process manager that handles the removal of the running process from the CPU and the selection of another process based on a particular strategy.

More recent systems (Windows NT) are back to having sophisticated CPU scheduling algorithms. What drove the change, and what will happen in the future? There is a pool of runnable processes …

Scheduling is the policy the operating system uses to time multiplexes the CPU between different tasks. A large number of scheduling policies have been developed over the years.

When a process (or thread) requests an IO transfer, it normally becomes ineligible to use the CPU until the transfer is complete. This means that the scheduler will have to choose a new process (or a new …

Take a real-time process only if the system can guarantee the “real-time” behavior of all processes. Assume periodic processes. The jobs are schedulable, if the following holds:
