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 What are the disadvantages of microkernels? What are placement and replacement algorithms in the context of memory management? Explain the handheld systems. How do I check for memory leaks?
