Here's a word you may not know...
modem
A modem is a device used to send and receive data over the Internet. Traditional modems utilized a dial up connection using land-based telephone lines. Modems are being phased out in favor of higher speed broadband Internet connections.
The term modem is still used today when referring to devices such as cable modems although this is really an incorrect use of the word modem. A modem, by definition, modulates and demodulates an analog signal and most broadband Internet connections are all digital requiring no modulating or demodulating.
