In the context of operating systems

n processes are time-sharing the CPU using RR scheduling, each requiring T ms of CPU time to
complete.
needs to show your work

(b) How long will the execution take on a single CPU machine when the context switch overhead is
zero?
(c) How long will the execution take on a single CPU machine when:
• the length of the time quantum is Q ms
the time to perform each context switch is S ms
(d) Repeat the previous calculation using n=5, T=10,000, Q=100, S=10.
