Full form of FAX

The full form of fax is facsimile. It is the telephone transmission of scanned copies of images and text printed on paper over a telephone line between two people. A fax machine is a device to transmit originals electronically or replicates scanned documents over a telephone network.

Fax processes the scanned text or image as one solid visual image and converts it to a bitmap. It then transmits it through an audio frequency through the telephone system. The fax machine deduces the tones on the receiving end, reconstructs the image, and prints a hard copy.

History of the FAX

In the twenty-first century, fax technology was rendered obsolete with the advent of e-mail with technological advancements. A brief history of the FAX is as follows:

  1. In 1843, Alexander Bain invented fax technology. He patented his "Electric Printing Telegraph."
  2. Then Frederick Bakewell improved upon Bain's invention and produced the telefax.
  3. Giovanni Caselli invented the "Pantelegraph" in 1861. It was the first commercially used telefax machine and introduced the first commercial telefax service.

Working Principle of FAX

  1. Fax is a complete set of scanners and printers.
  2. The scanner first scans the page and converts it to a solid graphic image, then converts it to a bitmap and sends it over the phone line via audio frequency.
  3. The receiving device interprets the signals and prints the reconstructed image on paper.
