Speakers are best classified under which type of device?

Speakers are classified as output devices because they are designed to convert electrical signals into sound waves that can be heard by a user. Their primary function is to output information, specifically audio, which is an essential part of many computing tasks, such as listening to music, multimedia presentations, or alerts from software applications.

Input devices, on the other hand, serve to send data to a computer and include devices like keyboards and mice. Since speakers do not perform this function and do not take data from a user, they do not qualify as input devices. Similarly, the description of a device functioning as both input and output implies functionality that speakers inherently do not possess, as they lack the capability to receive and process input signals. Thus, categorizing speakers solely as output devices accurately reflects their role in a computer system.
