Input and Output Devices in Your World
For the next 24 hours, notice what computer input and output devices you see in use at school, at
work, in your community, and at home. For example, at your local grocery store, you might see
a digital cash register with a bar code scanner and a thermal receipt printer, and you might see a
magnetic card reader for credit card processing. See how many devices from this chapter you can
