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 e&#64256;ectively wasted (overhead). The CPU’s e&#64259;ciency 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 e&#64259;ciency for each of the following: (a) Q = &#8734; (b) Q > S + T (c) S <Q<S + T (d) Q = S
