Fax is short for ‘facsimile’ which means ‘copy’. |
A fax machine is a device that can send a copy of a paper document over the telephone network.
- The sending fax converts the light/dark areas of the printed document into noises.
- These noises travel through the phone system and are received by another fax machine.
- The receiving fax machine converts the noises into printed marks on a piece of paper - making a copy of the original document.
