Definition
Facsimile Transmission (FAX):
Facsimile transmission, abbreviated as fax, refers to the telephonic transmission of scanned printed material (both text and images) typically to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a multifunction printer) which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap file. The fax machine then transmits this bitmap as audio-frequency tones over the telephone line to another fax machine. The receiving end’s fax machine reconverts the encoded image and prints a paper copy of the document.
Examples
- Business Contracts: Companies often use fax machines to send signed contracts and other legal documents that require signatures.
- Medical Records: Healthcare providers frequently fax patient information to other doctors or hospitals to secure timely medical consultation.
- Purchase Orders: Businesses often use fax to send purchase orders due to its immediacy and the verifiability of delivery.
Frequently Asked Questions
What is the difference between a fax and an email?
While both fax and email are used for sending documents, fax uses telephone lines to send scanned copies of documents to another fax machine, producing a paper output. Email transmits digital documents over the internet, which can be viewed on a computer or mobile device and printed if necessary.
Can I send a fax without a fax machine?
Yes, there are online services and software applications that allow you to send and receive faxes through email or a web interface, eliminating the need for a physical fax machine.
Is fax still widely used today?
Fax is still used in industries where signed documents are necessary or where regulations require document transmission in a manner that leaves a paper trail, such as legal, medical, and certain business sectors.
How secure is fax transmission?
Fax transmissions are generally considered secure as they are direct point-to-point connections over the telephone line. However, the physical documents can be misdirected or picked up by unauthorized individuals if not properly monitored.
