This document discusses computer hardware input devices, output devices, and storage media. It defines input devices as hardware used to enter data into a computer, such as keyboards, mice, and scanners. Output devices are defined as hardware that presents information from a computer to users, like monitors, printers, and speakers. Storage media are devices that store data, including floppy disks, hard disks, USB drives, and CDs/DVDs. Common input, output, and storage devices are identified and briefly described.
