Specialty I/O devices

“

- Computing devices can handle a ton of specialty input/output devices. Let's look at a few examples, starting small and getting bigger, just like we did in the last episode. This little PayPal device attaches to this smartphone and turns the smartphone into a point of sale system. It can handle credit cards and take my money, just like that. I've connected headphones to this laptop so that I get a little better sound when I'm outside, and I can cut out some of the background noise. This is a printer for outputting printed paper, and here's a game controller for gaming input, and a joystick for flight gaming, also an input device. Finally, here's a multifunction device that does all kinds of crazy input and output. It is a printer, output, and a scanner, input. A scanner takes a digital photograph, essentially, of something and brings it into the computer to work on. (upbeat music)
