No, a mouse is not an output device; it is an input device. The primary function of a mouse is to allow users to interact with a computer by providing input through movement and clicks.
To elaborate, input devices are hardware that send data to a computer, enabling user commands and interactions. The mouse translates physical movements into cursor movements on the screen, allowing users to point, click, and select items.
In contrast, output devices are used to convey information from a computer to the user. Examples of output devices include monitors, printers, and speakers, which present data generated by the computer in a usable format. Since a mouse does not provide output but rather receives input from the user, it does not fit the definition of an output device.
