Question

In the Shortest Remaining Time First (SRTF) scheduling algorithm, the process with the smallest amount of time remaining until completion is selected to execute. Since the currently executing process is the one with the shortest amount of time remaining by definition, and since that time should only reduce as execution progresses, processes will always run until they complete or a new process is added that requires a smaller amount of time.

Answer 1

The Shortest Remaining Time First (SRTF) scheduling algorithm is a preemptive scheduling method used in operating systems to execute the process with the shortest remaining time, potentially preempting the current process if a new one with less time arrives.

Step-by-step explanation:

The question discusses the Shortest Remaining Time First (SRTF) scheduling algorithm, which is used in operating systems to schedule tasks or processes. The SRTF algorithm selects the process with the smallest amount of time remaining to execute. As indicated in the scenario, when a process is currently executing, it by definition has the shortest remaining time. This process will continue to run unless interrupted by a new process that requires even less time to complete. The SRTF scheduling algorithm can preempt a currently running process if a new process arrives with a smaller execution time remaining. Therefore, it is a preemptive scheduling algorithm.
