Question 1

At the operating system level, file mapping is typically used for file caching, loading, and running executable programs.

Accepted Answer

This statement is true. File mapping allows the OS to map a portion of a file into virtual memory, which can improve performance when accessing the file or running programs from the file.

Question 2

A replacement policy determines which virtual page must be removed from memory to make room for a new page.

Accepted Answer

A replacement policy determines which virtual page must be removed from memory to make room for a new page.

Question 3

Much of Windows is written in assembly language, a programming language that's standardized and readily available.

Accepted Answer

While some portions of Windows may be written in assembly language, much of it is written in higher-level programming languages such as C++.

Question 4

One of the biggest concerns about Windows operating systems in general is the need for aggressive patch management to combat the many viruses and worms that target these systems.

Accepted Answer

This statement is true. Windows operating systems are frequently targeted by viruses and worms, therefore active patch management is necessary to ensure the system's security.

Question 5

To give fast response times when dealing with CPU-bound applications, all that is required is fast hardware.

Accepted Answer

Fast hardware can improve response times, but optimizing software, algorithms, and efficient resource management are also crucial for handling CPU-bound applications effectively.

Question 6

The I/O Manager allows device drivers and file systems, which it perceives as device drivers, to be loaded dynamically based on the needs of the user.

Accepted Answer

The statement is true. The I/O Manager is responsible for managing input/output operations in Windows operating systems and allows drivers to be loaded dynamically as needed.

Question 7

The Open Mode attribute for a file indicates whether other callers can open the file for read, write, or delete operations while this caller is using it.

Accepted Answer

The answer of The Open Mode attribute for a file...

Question 8

In 1999, Microsoft changed the operating system's name from Windows NT to Windows 2000.

Accepted Answer

In 1999, Microsoft did change the name of their operating system from Windows NT to Windows 2000.

Question 9

The SMB protocol is a high-level specification for formatting messages to be sent across the network and correlates to the application layer (layer 7), and the presentation layer (layer 6) of the OSI model.

Accepted Answer

The SMB protocol does indeed operate at the application and presentation layers of the OSI model.

Question 10

LDAP is the hierarchical replicated naming service on which the Internet is built.

Accepted Answer

LDAP is a protocol used for accessing and maintaining directory services, but it is not the naming service on which the Internet is built. The Internet uses the Domain Name System (DNS) as its naming service.

Question 11

To ensure the integrity of the Windows operating system code the designers separated operating system functions into a privileged executive process and a set of nonprivileged processes called "protected subsystems."

Accepted Answer

This is true. Windows operating system code is separated into a privileged executive process and protected subsystems to ensure security and stability. The executive process has access to all system resources, while the protected subsystems contain non-essential system functions and applications that do not require privileged access.

Question 12

Windows XP was the last Windows operating system built on the Windows 95 code.

Accepted Answer

Windows XP was built on the Windows NT code, not on the Windows 95 code.

Question 13

In the Windows operating systems, almost all low-level I/O operations are asynchronous.

Accepted Answer

Windows operating systems support asynchronous I/O operations through the use of non-blocking I/O functions, completion routines, and I/O notification mechanisms, such as I/O completion ports. This allows for efficient I/O processing without blocking the application, resulting in better performance and resource utilization.

Question 14

The primary file handling concept in current versions of Windows is the virtual file.

Accepted Answer

Virtual files are a fundamental concept in Windows file handling, providing a layer of abstraction between applications and the physical file system.

Question 15

Windows provides execution environments for applications that are different from its primary programming interface.

Accepted Answer

Windows provides various execution environments such as .NET Framework, Win32 API, etc. that are different from its primary programming interface.

Question 16

Windows is a non-preemptive-multitasking, multithreaded operating system.

Accepted Answer

Windows is a preemptive-multitasking, multithreaded operating system.

Question 17

A driver object can only have one device connected to it.

Accepted Answer

A driver object can manage multiple devices. In many operating systems, a single driver can handle multiple instances of a device or devices of similar types, allowing for more efficient management of hardware resources.

Question 18

The lower half of the virtual address space is accessible only to kernel-mode processes.

Accepted Answer

The lower half of the virtual address space is typically reserved for user-mode processes, while the upper half is reserved for kernel-mode processes.

Question 19

The first Windows application was not a true operating system.

Accepted Answer

The first Windows application, which was called Windows 1.0, was not a true operating system. It was a graphical user interface (GUI) that ran on top of MS-DOS, providing users with a more intuitive way to interact with their computer. It wasn't until Windows 95 that Microsoft released a true operating system that didn't rely on MS-DOS.

Question 20

Multithreading is advantageous when doing database searches because data is retrieved faster when the system has several threads of execution that are searching an array simultaneously, especially if each thread has its own CPU.

Accepted Answer

Multithreading allows for parallel processing, which can significantly speed up database searches by allowing multiple threads to search different sections of a database simultaneously. This is especially beneficial if each thread is assigned to its own CPU, which further increases processing speed.
