Computer Hardware Devices Questions

Multiple choice

Device drivers are

  1. Interface between H/W and S/W

  2. Used for driving the devices

  3. H/W components

  4. Both (1) and (2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Device drivers serve as the software interface between hardware components and the operating system, and are specifically designed to control and drive device operations. Option D correctly combines both essential characteristics: the interface function and the device control function.

Multiple choice

The sample sounds are stored in

  1. Wave synthesis cards

  2. Sound cards

  3. Analog cards

  4. SIM cards
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wave synthesis cards store and play back sampled audio sounds. They contain memory for holding audio samples and circuitry for playback, unlike sound cards which focus on audio processing and conversion.

Multiple choice

The most common input device used today is a(an) ___________.

  1. Motherboard

  2. VDU

  3. Keyboard

  4. IC chip
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The keyboard is the most common input device used with computers today for text entry, commands, and navigation. A motherboard (option A) is the main circuit board that holds other components, not an input device. A VDU (option B) is a Visual Display Unit, which is an OUTPUT device that displays information to the user. IC chips (option D) are internal electronic components.

Multiple choice

People who enter data into a computer through visual display terminals often suffer from eye strain due to poorly lit monitors or develop muscle stiffness. What is the name of the subject which studies the user machine interface as it relates to physical comfort?

  1. Office automation

  2. User-friendliness

  3. Computer stationery

  4. Ergonomics

  5. None of these

D Correct answer
Explanation

Ergonomics is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system.

Multiple choice

The monitor of a computer is connected to it by a

  1. Wire

  2. cable

  3. bus

  4. line driver
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Computer monitors are typically connected to the system unit via a cable (such as VGA, DVI, HDMI, or DisplayPort cables). While 'wire' is physically similar, 'cable' is the correct terminology for monitor connections. A bus is internal to the computer, and line driver is an electronic component, not a connection method.

Multiple choice

Which of the following is not an output device?

  1. Printer

  2. Keyboard

  3. VDU

  4. CRT
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An output device displays or presents information from the computer (printer, VDU-Visual Display Unit, CRT-Cathode Ray Tube monitor). An input device sends data TO the computer. A keyboard is an input device - you type on it to send information to the computer, making it the correct answer as 'not an output device'.

Multiple choice

Microfilm reader is

  1. OCR device

  2. COM device

  3. MICR device

  4. All of device
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Microfilm readers use OCR (Optical Character Recognition) technology to read text from microfilm and convert it to digital data. COM (Computer Output Microfilm) creates microfilm, and MICR (Magnetic Ink Character Recognition) is used for checks.

Multiple choice

Which of the following is an input device?

  1. Scanner

  2. Printer

  3. Monitor

  4. Plotter
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A scanner is an input device that captures physical documents or images and converts them into digital format for computer processing. Printers, monitors, and plotters are output devices.
