An external storage device
- B.
The computer's long-term memory
- C.
The computer's short-term memory
- D.
The memory that controls the computer.
Correct Answer
C. The computer's short-term memoryExplanation
RAM, or Random Access Memory, is a type of computer memory that is used to store data that is being actively used by the computer. It is considered the computer's short-term memory because it provides fast and temporary storage for data that the computer needs to access quickly. Unlike long-term storage devices such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off. Therefore, RAM is responsible for holding and providing quick access to data that is currently being processed by the computer.Rate this question:

To encrypt internet traffic
- B.
To store and manage email messages
- C.
To translate domain names into IP addresses
- D.
To monitor network bandwidth usage
Correct Answer
C. To translate domain names into IP addressesExplanation
A DNS (Domain Name System) server is responsible for translating human-readable domain names (such as www.example.com) into the numerical IP addresses (such as 192.0.2.1) used by computers to identify and communicate with each other over the internet. This process, known as DNS resolution, allows users to access websites using easy-to-remember domain names instead of complex IP addresses.Rate this question:

Digital cameras use film to capture digital imagery.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Digital cameras do not use film to capture digital imagery. Instead, they use image sensors to convert light into digital signals, which are then processed and stored as digital files. Film cameras, on the other hand, use photographic film to capture images, which need to be developed and printed before they can be viewed. Therefore, the statement that digital cameras use film is false.Rate this question:

Software that manages and controls the hardware resources on your system is known as:
- A.
Managing inventory software.
- B.
Application software.
- C.
Operating system software.
- D.
Hardware software.
Correct Answer
C. Operating system software.Explanation
The correct answer is operating system software because it is responsible for managing and controlling the hardware resources on a system. The operating system acts as an intermediary between the user and the computer hardware, providing services such as memory management, process scheduling, and device management. It allows applications to run and interact with the hardware, making it an essential component of any computer system.Rate this question:

You want to create a letter using your computer. What type of software will you need installed on your computer.
- A.
Only application software.
- B.
Only operating software.
- C.
Neither application software nor operating software.
- D.
Both application software and operating software.
Correct Answer
D. Both application software and operating software.Explanation
To create a letter using a computer, you will need both application software and operating software. Application software, such as word processing programs like Microsoft Word or Google Docs, allows you to type and format the content of your letter. Operating software, like Windows or macOS, provides the necessary environment for the application software to run on your computer. Without operating software, you would not be able to install or use the application software needed to create the letter. Therefore, both types of software are required.Rate this question:

. ________ are devices that connect to a computer and display a video image of whatever it is recording.
- A.
Digital Camera
- B.
Web Camera
- C.
Analog Camera
- D.
Video Camera
Correct Answer
B. Web CameraExplanation
A web camera is a device that connects to a computer and displays a video image of whatever it is recording. It is specifically designed for video communication and live streaming purposes. Unlike digital cameras, which are primarily used for capturing still images, web cameras are used for real-time video chats, video conferences, and online video streaming. Analog cameras, on the other hand, do not connect directly to computers and are not designed for displaying live video images. Video cameras, although similar to web cameras, are typically used for professional videography and recording high-quality videos rather than live video streaming.Rate this question:
