Weaving Photos into the Web

When the Internet was first opened to the general public, it was a text-only medium. One computer could send a message to others using a system not unlike the ones used by the telegraph company or news wire service. Signals went from the computer to a box called a modem, and then as tones over a telephone line to another computer. The signals again passed through a modem and were translated back into letters and numbers on the receiver's computer screen. The system was originally developed as a means of secure communication for science facilities, the armed forces, and university researchers. Eventually, it was opened to the general public.

Modem stands for modulate/demodulate. The modem translates ASCII text into audible signals that are sent back and forth on a normal telephone line.
