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 per swap operation and no head seeks are involved?

Consider a system with four processes and four resources: P1 holds R1 and requests R2 P2 holds R2 and requests R3 P3 holds R3 and requests R4 P4 holds R4 and requests R2 Each resource has exactly one instance. Which statement is correct?

A system has 18 instances of a single resource type, shared among n processes. If each process requires at most 5 instances, what is the maximum value of n for which the system can guarantee that a deadlock will never occur?
