In a time when most communication happens over email, instant messaging, and cloud storage, many people wonder why fax is still in use.

Understanding Fax Technology

What is a Fax?

A fax is a method of transmitting scanned documents from one device to another using a telephone line or an internet-based fax service. The recipient receives the document as an image or a printed copy.

How Fax Works

1. Scanning: The sender’s fax machine or app scans the document.
2. Encoding: The scanned image is converted into a digital signal.
3. Transmission: This signal is sent via phone line or internet.
4. Decoding: The recipient’s fax device or service converts it back to an image or printout.
