What is the main purpose of a microphone in a computer?

The main purpose of a microphone in a computer is to input sound into the computer. Microphones work by converting sound waves into electrical signals, which the computer can then process and use for various applications such as voice recognition, video conferencing, or audio recording. When using applications that require audio input, like a voice chat or dictation software, the microphone captures the user's voice and sends it to the computer for further processing. This function is essential for enabling interactive communication and multimedia experiences on a computer.

Other options do not align with the primary function of a microphone: enhancing video quality pertains more to cameras, increasing battery life is related to power management, and storing audio files is a function of storage devices, not a microphone.
