4 MB

c.

8 KB

d.

4 KB

Discuss
Answer: (d).4 KB Explanation:The default page size used in Windows on IA-32 processors is 4 KB.
Q23.
Do all processor architectures support the same page sizes?

a.

Yes, all architectures use the same page size

b.

No, some architectures support more than one page size

c.

No, each architecture has its own unique page size

d.

No, all architectures use different page sizes for virtual memory

Discuss
Answer: (b).No, some architectures support more than one page size Explanation:Some processor architectures support more than one page size.
Q24.
What is virtual memory in operating systems?

a.

A layer between the software and the physical memory

b.

A technique used to directly access physical memory

c.

A concept that allows direct access to the physical memory

d.

None of the above

Discuss
Answer: (a).A layer between the software and the physical memory Explanation:Virtual memory is a technique used by contemporary operating systems that creates an invisible layer between the software and the physical memory.
Q25.
What is a page table?

a.

A table that tells the process which physical memory address to actually use

b.

A table that divides memory into pages

c.

A table that deals with one page of memory

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:A page table is a table that tells the process which physical memory address to actually use, divides memory into pages, and deals with one page of memory.
Q26.
What is the most important benefit of using a page table?

a.

It enables the creation of multiple address spaces

b.

It enables direct access to physical memory

c.

It enables sharing of memory between processes

d.

None of the above

Discuss
Answer: (a).It enables the creation of multiple address spaces Explanation:The most important benefit of using a page table is that it enables the creation of multiple address spaces, which ensures that programs are completely isolated from one another.
Q27.
What is the concept of multiple address spaces?

a.

An isolated page table that only allows access to memory that is pertinent to the current program or process

b.

A fundamental feature in modern operating systems

c.

A feature that ensures that programs are completely isolated from one another

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Multiple address spaces is a concept that involves an isolated page table that only allows access to memory that is pertinent to the current program or process, is a fundamental feature in modern operating systems, and ensures that programs are completely isolated from one another.
Q28.
What is kernel mode in operating systems?

a.

The privileged processor mode

b.

Code that runs in privileged mode

c.

Memory that is only accessible while the processor is in privileged mode

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Kernel mode is the privileged processor mode and is frequently used for describing code that runs in privileged mode or memory that is only accessible while the processor is in privileged mode.
Q29.
What is paging?

a.

A process of flushing memory regions to hard drive

b.

A process of accessing memory regions from hard drive

c.

A process of allocating physical memory to applications

d.

A process of clearing physical memory

Discuss
Answer: (a).A process of flushing memory regions to hard drive Explanation:Paging is a process whereby memory regions are temporarily flushed to the hard drive when they are not in use.
Q30.
Why is paging used in virtual memory systems?

a.

To increase the speed of physical memory

b.

To reduce the cost of physical memory

c.

To make physical memory more reliable

d.

To prevent memory leaks

Discuss
Answer: (b).To reduce the cost of physical memory Explanation:Physical memory is much faster and much more expensive than hard drive space, it makes sense to use a file for backing up memory areas when they are not in use.
