Fax is a short word for "facsimile", which means a copy or reproduction of something. It refers to a machine that allows you to send and receive documents between two fax machines. It is often used in offices to quickly send paper documents from one place to another without having to mail them. Fax machines can also send and receive faxes through a computer or a smartphone that has a fax app installed. In modern times, the use of fax machines has decreased due to email and other digital communication methods.
