Facsimile is abbreviated as FAX. It is the most common spelling and pronunciation. It’s a scanned copy of text and graphics printed on paper sent over the phone from one party to another. Fax machines are devices that deliver documents electronically via a telephone network.
How FAX works ?
This machine is a mixture of scanner and printer exclusively. Scanner 1st scans the page and translates into Digital fixed graphic image and then bitmap and transfers it over telephone line.
It is a scanner and printer combined into one device. Scanner scans the page first, then turns it to a fixed graphic picture, bitmap, and sends it over the phone line. If a person has to send a document through fax, he inserts a piece of paper into the this machine, which keeps the copy of the document and turns it into a fixed graphic picture before sending it over the phone to the recipient.
History
Alexander Bain developed the fax technology in 1842. He was the first person to send image/text over telephone line signals. Later, Frederick Bakewell enhanced Bain’s innovation and built the first image telegraph, which is comparable to the this machine we use today.
When the newer technology known as “email” came into being in the twenty-first century, fax technology became obsolete.
