Which of the following best describes a Command Line Interface (CLI)?

• An interface that uses icons and images

• An interface that requires text commands

• An interface that uses voice commands

• An interface that presents options as menus

Answer explanation

A Command Line Interface (CLI) is characterized by its requirement for text commands, allowing users to interact with the system through typed input. This distinguishes it from graphical interfaces that use icons or menus.

How does an operating system manage multiple print requests from different users?

• By using caching

• By using spooling

• By using swapping

• By using paging

Answer explanation

An operating system manages multiple print requests by using spooling, which temporarily holds print jobs in a queue. This allows the system to efficiently handle requests from different users without conflicts.

What is a key advantage of a Graphical User Interface (GUI) over a Command Line Interface (CLI)?

• It is more secure

• It is easier for beginners to use

• It requires less memory

• It allows faster command execution

Answer explanation

A key advantage of a GUI is that it is easier for beginners to use, as it provides visual elements and intuitive navigation, making it more accessible compared to the text-based commands of a CLI.

Which type of user interface is most likely to be used in automated teller machines (ATMs)?

• Graphical User Interface (GUI)

• Command Line Interface (CLI)

• Menu-driven Interface (MDI)

• Voice User Interface (VUI)

Answer explanation

Automated teller machines (ATMs) primarily use a Menu-driven Interface (MDI) to allow users to navigate options easily through on-screen menus, making transactions straightforward and user-friendly.

What is the role of an operating system in managing shared resources?

• To provide antivirus protection

• To queue requests for shared resources

• To update software automatically

• To enhance graphics performance

Answer explanation

The operating system manages shared resources by queuing requests, ensuring that multiple processes can access resources like memory and CPU without conflict, thus maintaining system stability and efficiency.

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

• Resource Management

• User Interface

• Internet Browsing

• File Management

Answer explanation

Internet browsing is not a function of an operating system; it is typically performed by web browsers. In contrast, resource management, user interface, and file management are core functions of an operating system.

What is the primary purpose of a user interface in an operating system?

• To manage hardware resources

• To allow user interaction with the system

• To perform data encryption

• To execute background tasks

Answer explanation

The primary purpose of a user interface in an operating system is to allow user interaction with the system, enabling users to communicate and control the computer effectively.

Which of the following interfaces is most likely to be used in a server environment?

• Graphical User Interface (GUI)

• Command Line Interface (CLI)

• Menu-driven Interface (MDI)

• Voice User Interface (VUI)

Answer explanation

The Command Line Interface (CLI) is preferred in server environments due to its efficiency, speed, and ability to automate tasks through scripting, making it more suitable than GUIs, MDIs, or VIUs for server management.

What is the function of a Menu-driven Interface (MDI)?

• To provide a touch-based interface

• To present options as a series of menus

• To display graphical icons

• To execute background processes

Answer explanation

A Menu-driven Interface (MDI) functions by presenting options as a series of menus, allowing users to navigate and select commands easily. This makes it user-friendly and organized, unlike touch-based or icon-based interfaces.
