Input devices allow users to enter data and instructions into a computer. Common input devices include keyboards, mice, scanners, joysticks, microphones, and digital cameras. Keyboards are standard input devices that contain letter, number, and function keys. Mice are pointing devices that allow users to control the cursor on screen by moving the device across a surface. Scanners are used to digitize images, text, and barcodes.
