Description: The ‘Shortest Job First’ (SJF) strategy is a process scheduling algorithm that prioritizes the execution of jobs based on their execution time. This approach is based on the premise that shorter jobs should be attended to first, allowing for a reduction in the average waiting time of processes in a system. By selecting jobs with the least execution time first, CPU utilization is optimized, and the overall system efficiency is improved. This strategy is particularly useful in environments where multiple tasks or processes are managed, as it minimizes the time jobs spend in the waiting queue. Additionally, SJF can contribute to a better user experience, as shorter jobs are completed quickly, which can give the impression of a more agile and responsive system. However, this strategy can also present disadvantages, such as the possibility of longer jobs being indefinitely delayed, a phenomenon known as starvation. Despite this, ‘Shortest Job First’ remains a valuable technique in process scheduling across various computing environments, especially where fairness and efficiency are key priorities.
