Q41.

What is the maximum size of the memory address used by Windows?

2 GB

4 GB

8 GB

16 GB

Discuss

Answer: (b).4 GB Explanation:Windows uses a 32-bit (4 gigabytes) memory address that is typically divided into two 2-GB portions: a 2-GB application memory portion, and a 2-GB shared kernel-memory portion.

Q42.

How is the 32-bit memory address used by Windows divided?

Into a 2-GB application memory portion and a 2-GB shared kernel-memory portion

Into a 1-GB application memory portion and a 3-GB shared kernel-memory portion

Into two 2-GB application memory portions

Into a 3-GB application memory portion and a 1-GB shared kernel-memory portion

Discuss

Answer: (a).Into a 2-GB application memory portion and a 2-GB shared kernel-memory portion Explanation:The 32-bit memory address used by Windows is typically divided into a 2-GB application memory portion and a 2-GB shared kernel-memory portion.

Q43.

Why is the kernel memory portion of the memory address shared among all address spaces?

So that the kernel memory is always available, regardless of which process is currently running

To give all applications equal access to kernel memory

To increase the overall memory available to the system

To reduce the number of page faults generated by applications

Discuss

Answer: (a).So that the kernel memory is always available, regardless of which process is currently running Explanation:The kernel memory portion of the memory address is shared among all address spaces so that the kernel memory is always available, regardless of which process is currently running.

Q44.

What is the size of the address space available to applications in a 32-bit Windows system?

2 GB

4 GB

8 GB

16 GB

Discuss

Answer: (a).2 GB Explanation:One side effect of the design used by Windows is that applications only have a 31-bit address space—the most significant bit is always clear in every address, so the maximum size of the address space available to applications is 2 GB.

Q45.

What is the significance of a 32-bit number whose first hexadecimal digit is 8 or above?

It is not a valid user-mode pointer

It is a valid user-mode pointer

It is a valid kernel-mode pointer

It indicates the size of the memory being accessed

Discuss

Answer: (a).It is not a valid user-mode pointer Explanation:The most significant bit of a 32-bit number is always clear in every address available to applications. Therefore, a 32-bit number whose first hexadecimal digit is 8 or above is not a valid user-mode pointer.

Q46.

What is the primary reason for the division between kernel memory and user memory?

To prevent applications from accessing the operating system's internal data structures.

To allow more memory to be allocated for user-mode applications.

To speed up the performance of the operating system.

To allow easier debugging of the operating system.

Discuss

Answer: (a).To prevent applications from accessing the operating system's internal data structures. Explanation:The division between kernel memory and user memory is primarily for security reasons, as it prevents applications from accessing the operating system's internal data structures.

Q47.

How much of the 32-bit memory address is typically used for application memory in Windows?

1 GB

2 GB

3 GB

4 GB

Discuss

Answer: (b).2 GB Explanation:In Windows, the 32-bit memory address is typically divided into two 2-GB portions: a 2-GB application memory portion and a 2-GB shared kernel-memory portion.

Q48.

What is the purpose of the paged pool in the kernel space?

To store kernel-mode heaps that are used by all the kernel components.

To map all currently cached files in the system cache space.

To allow access to nonpaged memory that is always kept in physical memory.

To allocate conventional paged memory for most kernel components.

Discuss

Answer: (d).To allocate conventional paged memory for most kernel components. Explanation:The paged pool is a heap that is made up of conventional paged memory and is the default allocation heap for most kernel components.

Q49.

What is the system cache space used for in Windows?

To store kernel code and other kernel components in the kernel space.

To allow access to nonpaged memory that is always kept in physical memory.

To map all currently cached files using the cache manager.

To provide dynamic memory allocation based on available physical memory and user-configurable registry keys.

Discuss

Answer: (c).To map all currently cached files using the cache manager. Explanation:The system cache space is where the Windows cache manager maps all currently cached files, allowing the memory manager to manage the amount of physical memory allocated to each mapped file.

Q50.

How is the 32-bit memory address used in Windows operating systems divided?

Into a 2-GB application memory portion and a 2-GB shared kernel-memory portion

Into a 4-GB application memory portion and a 4-GB shared kernel-memory portion

Into a 2-GB user memory portion and a 2-GB kernel memory portion

Into a 1-GB application memory portion and a 3-GB shared kernel-memory portion

Discuss

Answer: (a).Into a 2-GB application memory portion and a 2-GB shared kernel-memory portion Explanation:In Windows operating systems, the 32-bit memory address is typically divided into a 2-GB application memory portion and a 2-GB shared kernel-memory portion. This allows the kernel memory to be always available, regardless of which process is currently running.
