Definition
Facsimile Transmission (Fax) is a method of transferring printed material through the use of electronic means. The process involves scanning a physical document to create a bitmap (a type of binary image representation), which is then transmitted over a network, commonly a telephone line, or through the Internet. The recipient’s fax machine decodes the bitmap and prints an exact replica of the original document.
Examples
- Sending Contracts: Businesses frequently use fax machines to send signed contracts quickly and securely.
- Medical Documents: Healthcare providers use fax to send patient records or prescriptions because fax machines can transmit these documents securely and in compliance with privacy regulations.
- Government Communications: Many government agencies rely on fax transmissions for sharing official documents where digital contracts or emails are not permissible.
Frequently Asked Questions (FAQs)
Q1: Is fax still in use today?
A1: Yes, many industries still rely on fax due to its ability to provide secure and reliable document transmission, particularly in fields requiring legal or medical privacy.
Q2: What is the primary difference between fax and email?
A2: Fax machines transmit a direct copy of a physical document using scanning technology and telephone lines, while emails send digital text and files over the internet.
Q3: Can I send a fax without a traditional fax machine?
A3: Yes, online fax services and email-to-fax technologies allow users to send faxes through the internet without a physical fax machine.
Q4: How does a fax machine ensure the document is transmitted securely?
A4: Fax machines use the public switched telephone network (PSTN) which is considered secure and less susceptible to interception compared to some forms of digital communication.
- Telecopier: Another term for a fax machine. It describes the device used in the facsimile transmission process.
- PSTN (Public Switched Telephone Network): The traditional telephone network used for voice communication and capable of transmitting fax data.
- Online Fax: A modern evolution of fax technology that allows sending and receiving faxes via email or an internet-based service.
- Scanning Device: Hardware that captures images from physical documents to create a digital format for transmission.

Fundamentals of Facsimile Transmission: Communications Basics Quiz
### Does fax transmission require an Internet connection to operate?
- [ ] Yes, an Internet connection is always required.
- [ ] No, fax machines cannot use Internet services.
- [x] Not necessarily; traditional fax uses telephone lines, but Internet-based faxing does exist.
- [ ] Yes, but only for incoming faxes.
> **Explanation:** Traditional fax machines use telephone lines to send and receive documents. However, modern Internet-based fax services allow sending and receiving faxes over the Internet.
### What type of network is traditionally used for fax transmission?
- [ ] Local Area Network (LAN)
- [ ] Wide Area Network (WAN)
- [x] Public Switched Telephone Network (PSTN)
- [ ] Cellular Network
> **Explanation:** The Public Switched Telephone Network (PSTN) is the traditional network used for fax transmission, enabling secure and reliable document transfer.
### Can online faxing be performed without a traditional fax machine?
- [x] Yes, using services and applications that convert digital documents into fax formats.
- [ ] No, a physical fax machine is always required.
- [ ] Only for sending but not for receiving.
- [ ] Yes, but only large enterprises can access these services.
> **Explanation:** Online fax services and applications allow users to send and receive faxes without needing a physical fax machine by converting digital documents into fax-readable formats.
### Why is fax preferred in some industries for transmitting documents?
- [ ] Because it is faster than email.
- [x] Due to regulatory and security compliance requirements.
- [ ] Fax is cheaper than other methods.
- [ ] Fax causes less data corruption.
> **Explanation:** Certain industries, like healthcare and legal services, prefer fax due to its compliance with regulatory and security requirements.
### What process does a fax machine use to reproduce the document at the recipient’s end?
- [ ] Digital Signal Processing (DSP)
- [x] Decoding of bitmap image and printing
- [ ] Optical Discs Translation
- [ ] Direct Binary Transfer
> **Explanation:** The recipient’s fax machine decodes the bitmap image of the document and prints it out as an exact replica of the original.
### What is the essential function of a scanning device in fax transmission?
- [ ] To send voice signals
- [x] To code a physical document into a bitmap format
- [ ] To conduct network protocols
