Modems
Modems are used to connect two computers over a phone line. Modem is
short for Modulator Demodulator. It's a device that converts data from digital
computer signals to analog signals that can be sent over a phone line. This is
called modulation. The analog signals are then converted back into digital data
by the receiving modem. This is called demodulation. A modem is fed digital
information, in the form of ones and zeros, from the CPU. The modem then
analyzes this information and converts it to analog signals, that can be sent
over a phone line. Another modem then receives these signals, converts them back
into digital data, and sends the data to the receiving CPU. At connection time,
modems send tones to each other to negotiate the fastest mutually supported
modulation method that will work over whatever quality line has been established
for that call. There are two main differences in the types of modems for PC,
internal and external modems.
