Measurements of a certain system have shown that the average process runs for a time T before blocking on I/O. A process switch requires a time S, which is effectively wasted (overhead). The CPU’s efficiency is the fraction of its time its spends executing user programs, i.e., executing user processes. For round robin scheduling with quantum Q, give a formula for the CPU efficiency for each of the following: (a) Q = ∞ (b) Q > S + T (c) S
