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 operating system components? How are data structures handled by ntfs? How long does it take to chkdsk 1tb? What is plumbing/piping? What are deadlock prevention techniques? When an input file is opened, what are the possible errors that may occur? Does 64bit mean 64bit? How do I stop blue screen? Which JVM parameter is used to control the stack size of a thread? Which is better 32 bit or 64 bit? Give a non-computer example of preemptive and non-preemptive scheduling? Explain the difference between trap and trapdoor?
