Explain why an operating system can be viewed as a resource allocator - ANS-The
operating system has to be able to allocate those resources.
Explain the purpose of an interrupt vector - ANS-A table of pointers to specific interrupt
handling routines.
What is a bootstrap program and where is it stored? - ANS-Loads the operating system
and stored in nonvolatile, ROM
What role do device controllers and device drivers play in a computer system? - ANS-
Device drivers handle processes separately from the CPU. Provides the interface
between the kernel and what lies on the other side.
Why are clustered systems considered to provide high-availability service? - ANS-
Clustered system when one goes out they can pick up the processing from the other. It
is a redundancy service.
Describe the operating system's two modes of operation. - ANS-User mode, kernel
mode
Why is main memory not suitable for permanent program storage or backup purposes?
Furthermore what is the main disadvantage to storing information on a magnetic disk
drive as opposed to main memory? - ANS-It's volatile. When you pull the plug it is gone.
The main disadvantage is that it is slow.
Computer systems can be divided into four approximate components. What are they? -
ANS-Hardware, OS, applications, user
