A microphone records sounds and voices that can later be played back, and is used to record information for learning or to share thoughts with others remotely. Speakers amplify sounds to be heard louder by multiple people at once and must be plugged in to use, to listen to sounds out loud. A video game chip is placed in a machine to create a virtual world for the user's entertainment when operating it.
