A VR Headset would be best categorised as
- A.
An Output Device
- B.
An Input Device
- C.
Storage
- D.
A Wearable Computer
Correct Answer
A. An Output DeviceExplanation
A VR headset can be best categorized as an output device because it primarily delivers visual and auditory information to the user. It displays virtual reality content, including images and videos, directly to the user's eyes and often includes built-in headphones or speakers to provide audio feedback. While it may have some input capabilities, such as tracking the user's head movements, its main function is to output sensory information rather than inputting data. Therefore, categorizing it as an output device is the most accurate classification.Rate this question:

Which of the following hardware components is least necessary in order for a computer to function?
- A.
CPU
- B.
HDD
- C.
RAM

Magnetic hard drives, SSD drives, Flash Media and Optical Disks are all examples of _____________ memory.
Correct Answer
SecondaryExplanation
Magnetic hard drives, SSD drives, Flash Media, and Optical Disks are all examples of secondary memory. Secondary memory refers to the non-volatile storage devices that are used for long-term data storage. These devices can retain data even when the power is turned off, making them suitable for storing large amounts of data that need to be accessed over a longer period of time. Unlike primary memory (RAM), secondary memory is not directly accessible by the CPU and requires the data to be transferred to primary memory before it can be processed.Rate this question:
