Computer Hardware Terms, Glossary and Dictionary

Fax machine, also known as facsimile machine, is a device that can send or receive pictures and text over a telephone line. A fax machine is essentially an image scanner, a modem, and a computer printer combined into a highly specialized package. The scanner converts the content of a physical document into a digital image, the modem sends the image data over a phone line, and the printer at the other end makes a duplicate of the original document.
