Meaning – A facsimile machine is one that is used to convert images into signals that can be easily transmitted over a telephone system. The same machine is also used to convert the image signals back into the original image on the receiver end.
Digital facsimile machines use modified Huffman and modified read data compression formats and scan 100-400 lines per inch (LPI).
Today, this machine is called a telefax, or simply, a fax machine.
Example of usage – “The manager requested his assistant to fax him the documents he required for the presentation as he forgotten to take them along with him and there was no time to make a return trip.”
