A fax, short for facsimile, is a device used to send and receive documents over a telephone line. It works by scanning a physical document, converting it into a digital signal, and transmitting it to another fax machine, which prints a copy of the document. Fax machines were widely used in offices and businesses to send contracts, forms, and other documents quickly and securely. While less common today due to digital communication methods, fax machines are still used in some industries that require signed or legally binding documents to be sent in their original form.
