COMPUTER FUNDAMENTALS

Detailed explanation-1: -They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear.

Detailed explanation-2: -Sometimes called earphones, headphones are a hardware output device that connect to a computer line out or speakers port or wirelessly with Bluetooth.

Detailed explanation-3: -When talking about computer I/Os, headphones with built-in microphones are both input and output devices. The headphones are output devices since the computer sends/outputs information to them. The built-in microphones are input devices since they send/input information into the computer.

Detailed explanation-4: -Detailed Solution The correct answer is Output. An output device is any device used to send data from a computer to another device or user. Most of the computer data output that is meant for humans is in the form of audio or video. Thus, most of the output devices used by humans are in these categories.

Detailed explanation-5: -Though headphones are regularly connected to digital audio sources, they are innately analog devices. Headphone transducers convert continuously variable (analog) audio signals (electrical energy) into sound waves (mechanical wave energy) and often require a digital-to-analog converter to function.
