Question

operating system question.

Problem Description Consider the following set of processes and arrival and processing time in- formation: Process Arrival Time Processing Time | C C C - Perform the same analysis as depicted in Table 9.5 and Figure 9.5 from our textbook for this set of processes. For the submission of this assignment for this class, you need to do FCFS, RR with a time quantum of 4, SPN, and SRT only (though I encourage you to also think about and try the HRRN and FB as well, once you complete the required scheduling policies).

Table 9.5 and figure 9.5:
