So input output, or I/O devices are the peripherals or hardware components that you attach to your computer which allow interaction between users and computers. Input devices allow users to send data to the computer. Output devices allow data to be exported or retrieved from the computer. Some common input devices are the keyboard, mouse, trackball, microphone, scanner, or joystick. Some common output devices are the monitor, printer, speakers, headphones. In addition to input and output devices, there are some that can function as dual input/output devices such as touchscreen monitors which can be touched to input data while simultaneously displaying the results as output on the screen. CD/DVD drives input the data to be read or executed, while outputting the data to the monitor or sound to speakers externally. USB drives can also perform along this same capacity.
