Q11.
What is virtual memory?

a.

A type of memory that is directly accessible to the CPU.

b.

A type of memory that is only accessible to the kernel of the operating system.

c.

A type of memory that is created by swapping data between the hard drive and physical memory.

d.

A type of memory that is used for running virtual machines.

Discuss
Answer: (c).A type of memory that is created by swapping data between the hard drive and physical memory. Explanation:Windows NT's memory manager employs a full-blown virtual-memory model.
Q12.
What is the Hardware Abstraction Layer (HAL)?

a.

A layer of the Windows NT kernel that isolates the system from the hardware and makes it easier to port the system to new hardware platforms.

b.

A layer of the Windows NT kernel that provides an Access Control List (ACL) for each individual file.

c.

A layer of the Windows NT kernel that encrypts individual files or entire volumes.

d.

A layer of the Windows NT kernel that executes old applications in a special isolated virtual machine.

Discuss
Answer: (a).A layer of the Windows NT kernel that isolates the system from the hardware and makes it easier to port the system to new hardware platforms. Explanation:Any physical hardware access in Windows NT goes through a special Hardware Abstraction Layer (HAL), which isolates the system from the hardware and makes it easier to port the system to new hardware platforms.
Q13.
What is an Access Control List (ACL)?

a.

A list of users who are allowed to manipulate a particular object in the Windows NT system.

b.

A list of files that are encrypted by the Windows NT File System (NTFS).

c.

A list of CPU-intensive applications that are supported by the Windows NT kernel.

d.

A list of 16-bit relics that are removed from the Windows NT architecture.

Discuss
Answer: (a).A list of users who are allowed to manipulate a particular object in the Windows NT system. Explanation:Every object in the Windows NT system has an associated Access Control List (ACL) that determines which users are allowed to manipulate it.
Q14.
What is the purpose of running old applications in a special isolated virtual machine in Windows NT?

a.

To prevent old applications from being able to access sensitive parts of the system.

b.

To allow old applications to run alongside newer applications without any compatibility issues.

c.

To improve the performance of old applications by giving them direct access to physical hardware.

d.

To make it easier to port old applications to new hardware platforms.

Discuss
Answer: (a).To prevent old applications from being able to access sensitive parts of the system. Explanation:Old applications are executed in a special isolated virtual machine in Windows NT where they cannot jeopardize the rest of the system.
Q15.
What processor architectures was the original Windows NT released for?

a.

IA-32 only

b.

DEC Alpha only

c.

Both IA-32 and DEC Alpha

d.

None of the above

Discuss
Answer: (c).Both IA-32 and DEC Alpha Explanation:The original Windows NT was designed as a cross-platform operating system, and was released for several processor architectures, including IA-32, DEC Alpha, and several others.
Q16.
Which 32-bit platform is currently supported by recent versions of Windows NT?

a.

IA-32 only

b.

DEC Alpha only

c.

Both IA-32 and DEC Alpha

d.

None of the above

Discuss
Answer: (a).IA-32 only Explanation:With recent versions of the operating system, the only supported 32-bit platform has been IA-32.
Q17.
Which 64-bit architectures are supported by recent versions of Windows NT?

a.

AMD64 and Intel EMT64

b.

DEC Alpha and Intel IA-64

c.

AMD64 and Intel IA-64

d.

None of the above

Discuss
Answer: (a).AMD64 and Intel EMT64 Explanation:Microsoft now also supports 64-bit architectures such as AMD64, Intel IA-64, and Intel EMT64.
Q18.
How does Windows NT memory manager handle virtual memory?

a.

It does not employ a virtual-memory model

b.

It employs a full-blown virtual-memory model

c.

It employs a partial virtual-memory model

d.

It employs a hardware-based virtual-memory model

Discuss
Answer: (b).It employs a full-blown virtual-memory model Explanation:Windows NT’s memory manager employs a full-blown virtual-memory model.
Q19.
What is the purpose of the Hardware Abstraction Layer (HAL) in Windows NT?

a.

To isolate the system from the hardware and make it easier to port the system to new hardware platforms

b.

To provide a layer of security for the system against malicious software

c.

To manage the physical hardware resources of the system

d.

To manage the virtual memory of the system

Discuss
Answer: (a).To isolate the system from the hardware and make it easier to port the system to new hardware platforms Explanation:Any physical hardware access goes through a special Hardware Abstraction Layer (HAL), which isolates the system from the hardware and makes it easier to port the system to new hardware platforms.
Q20.
What is the purpose of the page table?

a.

To store the physical memory addresses

b.

To manage the virtual memory

c.

To divide memory into pages

d.

To create an invisible layer between the software and the physical memory

Discuss
Answer: (b).To manage the virtual memory Explanation:The page table is a special table that manages the virtual memory and tells the process which physical memory address to use.
