Test 2 : Unit 2
Understanding Process Management in Operating Systems
This quiz is designed to test your knowledge on critical concepts related to process management in operating systems. With a series of questions, you'll get to explore various aspects that govern how processes interact within a system.
Whether you're a student or a professional, this quiz can help reinforce your understanding of key topics:
- Cooperating processes
- Semaphore operations
- Logical address space conventions
- Mutual exclusion methods

That can not drop below zero
That can not be more than one
3.If the size of logical address space is 2 to the power of m, and a page size is 2 to the power of n addressing units, then the high order _____ bits of a logical address designate the page number, and the ____ low order bits designate the page offset.
M, n
N, m
M – n, n
M – n, m
