Consider a System using Round Robin scheduling with 10 Processes all arriving at the time 0. Each Process is associated with 20 identical Request. Each Process request consumes 20 ms of CPU time after which it spends 10 ms of time on I/O,thereafter intiates subsequent Request. Assuming scheduling Overhead of 2 ms and Time Quantum of 20 ms, Calculate
i. Response time of the 1st Request of the 1st Process.
ii. Response time of the 1st Request of the last Process.
iii. Response time of the subsequent request of any process.
