What is the difference between fax and mail?

Fax and mail are both methods of transmitting information, but they differ in their processes and speed. Fax (short for facsimile) involves sending scanned documents over a telephone line to another fax machine, allowing for near-instantaneous transmission. In contrast, mail typically refers to the physical delivery of letters and packages through postal services, which can take days or weeks. Additionally, faxes are digital transmissions, while mail involves tangible items being physically transported.
