Most people on the Internet have connected
using a modem. A modem is an electronic device that can take binary
digits and transfer those electronic signals
into sounds of two different pitches. This allows pictures,
text, video, and other forms of computer information to travel across phone
(analog) lines. A modem can also decode these pitches back into
binary digits (or electronic signals). Each digit (or signal) is referred
to as a bit. Most modems sold today transfer bits at a rate of either
28,800 bps (bits per second) or 33,600 bps .Note: When two modems are connected, the lower speed of the two modems is the speed at which the two computers communicate.
