The monitor, printer and headphones produce output from the computer. The monitor allows the user to view data, while the printer produces hard copies of data. Headphones output sound, and a USB drive provides both input and storage capabilities.

Peripherals can be attached to the central processing unit either wirelessly or through a wired connection. Some peripherals, such as CD drives, are located inside the computer case or CPU, while other peripherals are external.
