Q1Which of the following is an example of a hard-copy output device?
Hard copy means output printed on a physical medium, usually paper. A printer is the common output device used to produce such printed copies of documents, images or reports. The stem asks specifically for a hard-copy output device, so sound output from a speaker and screen output from a monitor do not fit. A projector also only displays an image for viewing. Hence, the correct answer is printer.
Q2Read the Assertion (A) and Reason (R) and choose the correct option. Assertion (A): Speakers are output devices. Reason (R): Speakers convert computer audio signals into sound that the user can hear.
Speakers are output devices because they present the result of computer processing as sound. The assertion is therefore true. The reason is also true: speakers receive audio signals from the computer and convert them into audible sound waves. This is exactly the function that makes them output devices, just as a monitor gives visual output and a printer gives printed output. Since the reason correctly explains the assertion, option A is the best answer.
Q3Statement 1: A projector is an output device used to display computer visuals on a large screen. Statement 2: A projector is most useful when the same display has to be shown to a group, such as in a classroom or presentation hall. Which option is correct?
Both statements are correct. A projector receives visual output from a computer and throws it on a large screen, wall or projection surface. This makes it an output device, just like a monitor, but it is meant for a larger audience. The second statement explains the practical cue: classrooms, meetings and presentation halls use projectors because several people need to see the same screen at once. It is not an input or storage device, and it does not create paper output like a printer.
Q4Assertion (A): Headphones are output devices. Reason (R): Headphones convert the computer's audio signal into sound that a user can hear. Choose the correct option.
The assertion is true because headphones are used to receive sound from a computer, mobile device, or other digital system. They do not send the user's voice or data into the computer; they present the processed audio result to the user. The reason is also true: headphones convert an electrical or digital audio signal into audible sound. This conversion is exactly why they are classified as output devices. Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.
Q5Match List I with List II and choose the correct answer. List I: I. Monitor II. Printer III. Speaker IV. Projector List II: 1. Displays output on a large screen or wall 2. Produces sound output 3. Shows soft-copy visual output 4. Produces printed output on paper
Each device is identified by the form of output it gives. A monitor shows soft-copy visual output, so I matches 3. A printer gives printed output on paper, so II matches 4. A speaker gives audio or sound output, so III matches 2. A projector takes the visual signal and displays it on a large screen or wall for an audience, so IV matches 1. The only option carrying this full sequence is A.
