What is the primary function of a microphone in a computer system?

• A. Output sound
• B. Input sound
• C. Store audio data
• D. Process audio signals

Answer: (B)

The primary function of a microphone in a computer system is to input sound. Microphones convert acoustic energy, such as sound waves from a person's voice or other noise, into electrical signals. These electrical signals can then be processed by the computer for various purposes, such as voice recognition, communication through applications like video conferencing, or audio recording. Microphones do not output sound; that is the role of speakers or other output devices. While some devices may store audio data, the microphone itself does not have internal storage; it merely captures sound for immediate processing or transmission. Processing audio signals typically involves software or hardware components in the computer, such as sound cards or audio interfaces, rather than the microphone itself. Thus, the correct answer highlights the microphone's role in capturing and inputting sound into the system.
