Discuss a Thread Life Cycle?
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 How many types of file systems are there? What mean operating system? What is the purpose of system programs? What are overlays? What are the advantages of multiprocessor system? Explain the trda? Explain booting the system and bootstrap program in operating system. What does thread safe mean? Explain how a TP Monitor manages memory and processor
resources more effectively than a typical operating system. Will chkdsk fix corrupt files? What are the basic operations? What is dynamic scheduling in operating system (os)? Explain the Difference between Process and a Thread.
