UGC NET Questions (Paper – 1)

A printer takes digital documents from a computer and converts them into printed output on paper or other media. It is therefore classified as an output device because information flows from the computer to the external world. Printers can use different technologies such as inkjet, laser or dot matrix. Thus the hard-copy device described in the question is a printer.

Option A:
Option A, mouse, is used for pointing and clicking and is an input device, not one that produces printed output. It helps control the computer rather than generate hard copies.

Option B:
Option B, microphone, converts sound into electrical signals and is used to input audio, so it cannot be the device mentioned in the stem.

Option C:
Option C, scanner, captures images or text from paper into the computer and is therefore an input device, opposite in function to a printer.

Option D:
Option D is correct because producing printed text or graphics is the primary function associated with printers in ICT and office environments.
