What type of device includes components like a mouse, printer, or keyboard?

The correct answer is peripheral because it encompasses devices like a mouse, printer, and keyboard, which are external components that connect to a computer to enhance its functionality. Peripherals typically serve a specific purpose: input devices like keyboards and mice allow users to interact with the computer, while output devices like printers provide a way to receive information from the computer in a tangible form.

Input devices specifically refer to hardware that allows the user to provide data to a computer system. While keyboards and mice fall within this category, the term 'peripheral' is more inclusive, as it also covers output devices and other accessories that are not strictly input.

Storage devices, on the other hand, are used to save and retrieve data, such as hard drives and flash drives, which do not fit the description of the mentioned components. Network devices pertain to equipment needed for network communication, like routers or switches, which is separate from the user interface elements represented by peripherals.
