Sensors collect large quantities of _____________ data.
-
Computer
-
Digital
-
Biometric
-
Analogue
Correct Answer
A. AnalogueExplanation
Sensors collect large quantities of analogue data. Analogue data refers to continuous signals that can take on any value within a range. In the context of sensors, analogue data is collected by measuring physical quantities such as temperature, pressure, or light intensity. This data is typically represented as a continuous waveform and can be converted to digital form for processing by a computer.Rate this question:

Which output device would be the most suitable for printing out large architectural plans?
-
Laser printer
-
Ink-jet printer
-
Plotter
-
Dot-matrix printer
Correct Answer
A. PlotterExplanation
A plotter would be the most suitable output device for printing out large architectural plans because it is specifically designed for printing large-scale drawings with high precision. Unlike laser or ink-jet printers, which are better suited for smaller documents or images, a plotter uses a pen or marker to draw continuous lines on paper, allowing it to produce detailed and accurate prints of architectural plans. Additionally, a plotter can handle different paper sizes and thicknesses, making it ideal for printing out large-scale plans commonly used in architecture.Rate this question:

Which output device would be the most suitable when using a laptop?
-
Laser printer
-
TFT monitor
-
Speakers
-
CRT monitor
Correct Answer
A. SpeakersExplanation
While all of the options listed are types of output devices, speakers are typically the most suitable and practical for use with a laptop. This is because laptops often have limited built-in speaker quality and volume, and external speakers can enhance audio output for music, videos, games, and other multimedia applications.Rate this question:

Which output device would be the most suitable for producing carbon copies of an invoice?
-
Plotter
-
Ink-jet printer
-
CRT monitor
-
Dot-matrix printer
Correct Answer
A. Dot-matrix printerExplanation
A dot-matrix printer would be the most suitable output device for producing carbon copies of an invoice. This type of printer uses a print head that strikes an ink ribbon against the paper, creating a series of dots to form characters and images. The impact of the print head allows the ink to transfer onto multiple layers of paper, making it possible to produce carbon copies. Other devices such as plotters, ink-jet printers, and CRT monitors do not have the ability to create carbon copies.Rate this question:

Which output device would be the most suitable to show whether the equipment was turned on or had been switched off?
-
Plotter
-
LED bulb
-
TFT monitor
-
Speakers
Correct Answer
A. LED bulbExplanation
An LED bulb would be the most suitable output device to show whether the equipment was turned on or had been switched off. LED bulbs are commonly used as indicators to provide a visual indication of the power status. When the equipment is turned on, the LED bulb will light up, indicating that it is powered on. Conversely, when the equipment is switched off, the LED bulb will not light up, indicating that it is powered off. This makes LED bulbs an ideal choice for displaying the power status of the equipment.Rate this question:

Which output device would be the most suitable for printing a large number of high-quality black and white letters?
-
Plotter
-
Dot-matrix printer
-
Laser printer
-
Ink-jet printer
Correct Answer
A. Laser printerExplanation
A laser printer would be the most suitable output device for printing a large number of high-quality black and white letters. Laser printers use a laser beam to create an electrostatic image on a drum, which then attracts toner particles to create the image on the paper. This technology allows for precise and sharp printing, making it ideal for producing high-quality text. Additionally, laser printers have a fast printing speed and can handle large volumes of printing, making them efficient for printing a large number of letters.Rate this question:

Which output device would help to create an atmosphere when using a computer game?
-
Speakers
-
Laser printer
-
LEDs
-
Plotter
Correct Answer
A. SpeakersExplanation
Speakers would help to create an atmosphere when using a computer game by providing audio output. They allow the user to hear sounds, music, and dialogue, enhancing the immersive experience of the game. Speakers can produce a wide range of sounds, including background music, sound effects, and character voices, which contribute to the overall atmosphere and realism of the game.Rate this question:

Which output device would be the most suitable for printing out a few leaflets in color at home?
-
Plotter
-
Dot-matrix printer
-
Ink-jet printer
-
Laser printer
Correct Answer
A. Ink-jet printerExplanation
An ink-jet printer would be the most suitable output device for printing out a few leaflets in color at home. Ink-jet printers are capable of producing high-quality color prints with vibrant colors and sharp details. They are also relatively affordable and easy to set up and operate, making them convenient for home use. Additionally, ink-jet printers use liquid ink that is sprayed onto the paper, resulting in smoother color gradients and better color accuracy compared to other types of printers like dot-matrix or laser printers.Rate this question:

Which output device would be the most suitable if you wanted to view your work as you were creating it?
-
Monitor
-
Lights
-
Printer
-
Speaker
Correct Answer
A. MonitorExplanation
A monitor would be the most suitable output device for viewing work as it is being created because it provides a visual display of the content in real-time. This allows the user to see any changes or edits being made immediately and make adjustments accordingly. The other options, such as lights, printer, and speaker, do not provide a visual representation of the work and are not designed for real-time viewing.Rate this question:
