Facsimile or FAX is another area where computers are taking over. FAX machines have been used for a long time to transfer documents by scanning and sending over telephone lines.
You can plug in an add-on card, called the FAX card, into your PC. This will enable you to send the file on the disk to a FAX machine at the other end, and vice versa.
On a Local Area Network, if the FAX card is installed on one PC, other workstations of the LAN can utilize its services to send FAXs.
