Shortest job first sjf scheduling

SpletShortest Job First (SJF) CPU scheduling algorithm is a CPU scheduling algorithm which is based on the principles of Greedy Algorithms. The key idea is to allocate the CPU to the process with the smallest burst time so that the CPU seems to be more responsive. Burst time is the amount of time required by a process for its execution on the CPU.

Splet29. dec. 2024 · What is the shortest job scheduling? The shortest job first is one of the CPU scheduling algorithms. It is an algorithm in which the process depends on its burst time. In short, a process that has less burst time takes first place in the execution. The shortest job first (SJF) is also known as the shortest job next (SJN). For example, we have 4 ...
