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 Briefly explain the concept of Virtual Memory. Why would a parent process terminate a child process? What do you understand by registers? How do I search all files in windows?
