Computer devices that are not part of the essential computer (i.e. the memory and microprocessor). Peripheral devices can be external and internal.
- Printer
Devices that print text or illustrations on paper. There are many different types of printers.
- Scanner
Devices that can read text or illustrations printed on paper and translate the information into a form the computer can use. A scanner works by digitizing an image — dividing it into a grid of boxes and representing each box with either a zero or a one, depending on whether the box is filled in.
