A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance.

A common external connector is the microphone connector. Input through a microphone connector can be used, for example, by speech recognition or voice over IP applications. Most sound cards have a line in connector for an analog input from a sound source that has higher voltage levels than a microphone.
The jack redirects the audio to the speakers if no headphone connection is detected. Similarly, the return pins ground the microphone jack connection if no microphone detected. As a result, most motherboards with AC'97 audio require two jumpers to short these pins if no front panel audio module is connected, so audio passes to the speakers.
A peripheral can be categorized based on the direction in which information flows relative to the computer: The computer receives data from an input device; examples: mouse, keyboard, scanner, game controller, microphone and webcam; The computer sends data to an output device; examples: monitor, printer, headphones, and speakers

Two pins are used for the mono headphone signal and two pins for the unbalanced microphone signal. The 4-pin XLR connector is also commonly used on amateur radio microphones, but transferring unbalanced audio instead, and using the 4th pin (with the common ground) for a push-to-talk (PTT) circuit activated by a button on the microphone.
In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device. Some computer devices can also be categorized as input devices [1] because we use these devices to send ...
