Which of the following is an example of an input peripheral?

A mouse is an example of an input peripheral because it is a device that allows users to interact with a computer by providing input commands. The primary function of a mouse is to enable the user to control the cursor on the screen, facilitating actions such as selecting, dragging, or clicking on various items within graphical user interfaces. Input peripherals, like a mouse, are essential for user interaction, as they convert physical movement into signals that the computer can understand.

In contrast, other options represent output peripherals, which send information from the computer to the user. A monitor displays visual output, a speaker emits audio output, and a printer produces hard copies of digital documents. Understanding the distinction between input and output devices is fundamental in grasping how peripherals function within a computing environment.
