👉 Fax computing refers to the technology that allows users to transmit and receive documents electronically over telephone lines, similar to traditional fax machines. It works by converting scanned images of documents into digital signals, which are then sent over the same network as voice calls. On the receiving end, these signals are converted back into physical copies of the documents using printers. Fax computing relies on standards like X.25, T.30, and more recently, SDP (Session Description Protocol) for efficient data transfer. While it has largely been replaced by digital document sharing methods like email and cloud storage, fax computing still holds significance in certain industries for its reliability and ability to transmit large files quickly over long distances.
