Previous Year Question (PYQs)



What is the total swap time (Swap in & Swap out) in a system for a 15 MB process with a transfer rate of 30 MBps. Given that there is an average latency of 12 ms, however no head seeks involved.





Solution

Total swap time = 2 × (Transfer time + Latency) Transfer time for 15 MB = 15 / 30 = 0.5 sec So, Total time = 2 × (0.5 + 0.012) = 1.024 sec
