Answer (1)
2. State 'True' or 'False'.
a) True : Users receive data from output devices, such as monitors and speakers.
b) True : Monitors display results, making them a visual output device.
c) True : CRT (Cathode Ray Tube) monitors are considered old technology compared to modern LCD or LED monitors.
d) False : Inkjet printers are non-impact printers because they spray ink onto the paper rather than striking a ribbon against the paper.
e) True : Speakers are considered softcopy output devices because they produce sounds rather than physical copies.
f) False : Plotters use pens or other marking instruments to draw on paper, not toner.
3. Match the following.
LCD - New technology monitor
CRT - Old technology monitor
Laser printer - Non-impact printer
Speaker - Produces sound output
Plotter - Prints using pens
4. Write appropriate technical term for the following.
a) Soft copy : Output obtained in digital form is often referred to as soft copy, which can be displayed on screens or stored digitally.
b) Laser printer : A printer that uses light to create an image on a drum before transferring toner to paper.
c) Plotter : A plotter is specifically designed for printing large maps and technical drawings by moving a pen over the surface of the paper.
5. Choose the best answer.
a. Which device does not belong to the output unit? ii) Mouse : The mouse is an input device, not an output device.
b. ...provides output. ii) Plotter : A plotter is an output device that produces hard copies of large designs, maps, and technical drawings.
c. Which is the example of an output device? ii) Printer : A printer is a device that provides a physical (hard copy) representation of documents from a computer.
