Answer 2

A. Shortest job first scheduling policy is best suited for time-sharing operating systems.

Advantages and disadvantages:

• A scheduling strategy known as "shortest task first" chooses the process with the shortest execution time to run next. Preemptive or non-preemptive ordering is both possible for shortest work first.
• Shortest job first is seen to be the best practise due of its simplicity.
• It also cuts down on the typical amount of time that other operations take to execute.The terms shortest job first (SJF), shortest job next (SJN), and shortest process next are frequently used (SPN).
• There are certain drawbacks to the shorter tasks being completed first. One effect of having several shorter processes is that it may result in process hunger for larger workloads.
• Another is the requirement to be aware of each process's anticipated execution time. This is frequently so difficult in so many settings.
