To determine which scheduling algorithm has the highest CPU overhead, we need to analyze each algorithm and compare their characteristics.

1. First come, first served (FCFS): This algorithm schedules processes in the order they arrive. It has a simple implementation but can lead to high CPU overhead, especially if long-running processes arrive first. However, we cannot conclude that FCFS has the highest CPU overhead without comparing it to other algorithms.

2. Round-robin (RR): This algorithm allocates a fixed time slice to each process in a cyclic manner. It ensures fairness by giving each process an equal opportunity to execute. While RR may introduce some overhead due to context switching, it is generally considered to have lower CPU overhead compared to FCFS.

3. Shortest job first (SJF): This algorithm schedules processes based on their burst time, with the shortest job being executed first. SJF aims to minimize the waiting time and maximize CPU utilization. It typically results in lower CPU overhead compared to FCFS and RR, as it prioritizes shorter jobs.

Based on the analysis, the scheduling algorithm with the highest CPU overhead is FCFS.
