A joystick is an input device. It receives input from the user in the form of it's operation which it then passes on to the computer. Speakers are an example of an output device. They receive no input from the user, and only output (sound in this case). You can think of an input device as something that gives the computer information. And an output device as something that receives information from the computer.
If they are for hearing then its output device as they are not putting anything in to the computer, if they have a microphone attached as well then they are input/output (i.e. microphone is input, speakers are output)
A microphone is a device with an electrical output. An acoustic wave is the input. Its only function is to 'capture' sounds and convert them into an electrical signal for processing by the computer.
A Microphone does not output sound. It accepts sound. It is an input device.
Head sets have speakers on two ears and a microphone. The speakers are output devices and the microphone is an input device. So if a headset is an input/output device.
2nd keyboard or mouse, often attached via USB
The sound card of a computer provides an output - speaker or headphone) and usually an input too - microphone.The card itself is not an output but is an I/O device(input output device) [a bit of semantics here].
Microphone converts Audible Sound into digital signals that's why it will be considered as an INPUT device not an Output device.
an input device is something you use to put information into the computer. E.G. a keyboard or mouse. in sound terms this could be a microphone. An output device is something that lets the computer give information to you. E.g, a monitor, or in sound terms, speakers.
The difference is input programs information output tells you information
Input because your inputing a sound into the computer. Output is when something is outputting something like speakers.
