What is the SRTF Algorithm?
Shortest Remaining Time First (SRTF) is the preemptive version of the Shortest Job Next (SJN) algorithm, where the processor is allocated to the job closest to completion. It is also known as Shortest Job First with dynamic priority. It is a CPU scheduling algorithm of the Operating System.
In SRTF with predicted time, each process is assigned a priority based on its expected remaining burst time. The process with the highest priority (i.e., the shortest predicted remaining burst time) is selected to execute next. The predicted burst time is updated dynamically as the process runs, and the priority is recalculated based on the edited expected burst time.

CPU scheduling algorithms are essential components of operating systems that determine the order in which processes are executed on a computer’s central processing unit (CPU). These algorithms aim to optimize CPU utilization, reduce waiting times, and enhance system performance by efficiently managing the execution of tasks in a multi-tasking environment. Various algorithms, such as First-Come, First-Served (FCFS), Shortest Job Next (SJN), Round Robin (RR), and Priority Scheduling, are employed to achieve these objectives, each with its own set of advantages and limitations. In this article, we study about Shortest Remaining Time First CPU Scheduling algorithm.
