Question

The need to know or estimate required processing times for each process, the starvation of longer processes, and the lack of preemption are all difficulties with the __________ scheduling technique.

Answer 1

The difficulties with the First-Come, First-Served (FCFS) scheduling technique in operating systems are the need to know or estimate processing times for each process, the problem of starvation of longer processes, and the lack of preemption.

Step-by-step explanation:

The difficulties mentioned in the question are associated with the First-Come, First-Served (FCFS) scheduling technique in Operating Systems.

FCFS scheduling treats processes in the order they arrive. However, estimating processing times becomes problematic as longer processes may result in other processes waiting for extended periods (starvation) and once a process starts, it cannot be preempted or interrupted.

Example: Consider a scenario where multiple processes arrive in quick succession. If a long process arrives first, all subsequent processes have to wait, leading to decreased efficiency and possible starvation.
