Operating System Quiz 1

2.

Copying a process from memory to disk to allow space for other processes is called?

Swapping
Deadlock
Demand Paging
Page Fault

Correct Answer

A. Swapping

Explanation

Swapping is the correct answer because it refers to the process of moving a process from the main memory to the disk temporarily. This is done to free up space in the memory for other processes that are waiting to be executed. Swapping allows for efficient memory management and ensures that the system can handle multiple processes simultaneously.

Which runs on computer hardware and serves as platform for other software and the user program?

System software
System operations
Operating system
Utilities

Correct Answer

A. Operating system

Explanation

The operating system is a software that runs on computer hardware and serves as a platform for other software and user programs. It manages computer resources, such as memory, processes, and devices, and provides a user-friendly interface for users to interact with the computer. System software, system operations, and utilities are all related to the functioning of a computer system, but the operating system is specifically responsible for coordinating and controlling the overall operations of the computer.

4.

Which of the following is the primary purpose of an operating system?

To make the most efficient use of the computer hardware
To allow people to use the computer
To keep systems programmers employed
To make computers easier to use

Correct Answer

A. To make the most efficient use of the computer hardware

Explanation

The primary purpose of an operating system is to make the most efficient use of the computer hardware. Operating systems are responsible for managing and allocating system resources such as CPU, memory, and storage to ensure optimal performance. They provide a layer of abstraction between the hardware and software, allowing applications to run smoothly and efficiently. By efficiently utilizing the computer hardware, operating systems enhance the overall performance and productivity of the system.

5.

One of the function of operating system is it serves an interface between user and ______ ?

Software
Hardware
Utilities
Data ware

Correct Answer

A. Hardware

Explanation

The operating system serves as an interface between the user and the hardware. It manages and controls the hardware resources of a computer system, allowing the user to interact with the computer through various software applications. Without the operating system, the user would not be able to access or control the hardware components of the computer effectively. Therefore, the correct answer is hardware.

Which Operating System does not support long file names?

OS/2
Windows 95
MS-DOS
Windows NT

Correct Answer

A. MS-DOS

Explanation

MS-DOS is the correct answer because it was a command-line based operating system that was developed before the introduction of long file names. MS-DOS used the 8.3 file naming convention, which allowed only a maximum of 8 characters for the file name and 3 characters for the file extension. It did not have support for long file names with more than 8 characters. In contrast, OS/2, Windows 95, and Windows NT all supported long file names, allowing users to have more descriptive and longer file names.

Which Operating System does not support networking between computers?

Windows 3.1
Windows 95
Windows 2000
Windows NT

Correct Answer

A. Windows 3.1

Explanation

Windows 3.1 does not support networking between computers. It is an older operating system that was released in 1992, before networking capabilities became common in personal computers. Windows 3.1 was primarily designed for single-user systems and did not have built-in networking features. In contrast, Windows 95, Windows 2000, and Windows NT all introduced networking capabilities, allowing users to connect multiple computers together and share resources such as files and printers.

8.

It is used in operating system to separate mechanism from policy?

Single level implementation
Two level implementation
Three level implementation
Multi level implementation

Correct Answer

A. Two level implementation

Explanation

Two level implementation is used in operating systems to separate the mechanism from the policy. This approach allows for a clear distinction between the underlying mechanisms of the operating system, such as process scheduling and memory management, and the policies that determine how these mechanisms are implemented, such as the specific algorithms and rules used. By separating the mechanism from the policy, it becomes easier to modify or replace the policy without affecting the underlying mechanisms, making the operating system more flexible and adaptable to different requirements.

9.

Which of the following is NOT a function of operating system?

Resource Manager
Storage Manager
Process Manager
Software Manager

Correct Answer

A. Software Manager

Explanation

The operating system is responsible for managing various resources such as memory, CPU, and devices, which are necessary for the proper functioning of a computer system. It also manages processes, which are running programs, and ensures their efficient execution. Additionally, the operating system handles storage management, which involves organizing and controlling the storage space on the computer's storage devices. However, the software manager is not a function of the operating system. It is typically the responsibility of the user or system administrator to manage software installations, updates, and removals.

10.

The operating system creates virtual ____ from the physical computer.

Space
Computer
Device
Memory

Correct Answer

A. Computer

Explanation

The operating system creates virtual computer from the physical computer. This means that the operating system creates a simulated or virtual version of the computer's hardware and resources, allowing multiple virtual machines or environments to run on a single physical machine. This enables better utilization of resources and allows for easier management and isolation of different computing environments.
