Cable modem
Because of your computer's modem, you are able to access and read this webpage, as well as the rest of the internet. The full name of this technology is Modulator-Demodulator, Modem for short. A modem converts digital information and sends it from a telephone or telephone wires to a computer and vice versa. So Random Access Memory would have nothing to remember from the internet. Telephones use a digital method for their digital codes, while computers use analog that have different frequency currents. It makes both information compatible with each other. There are three types of modems: external, internal, or a pc modem card. External modems plug in to an electrical socket. You can turn it off and turn it on without it affecting the Central Processing Unit you are using. Internal modems are placed inside the computer which makes them easier to use, but more difficult to repair or replace. PC modem cards require a telephone connection and plug right in the side of a PC near the Optical Drive.

History of the Modem -

The first digital modem was created in the late 1950's so that North American Air and the US Air Force could transmit data they needed. The first ones for commerical use, though, were made in the 1960's. The first one was very slow, it was only 100 bps (bits per second). Then it increased to 300 bps, and by the 1980's and 1990's it went from 1200 bps to 9600 bps. Now, however, most people use wireless networks instead of telephone cable modems because of the slow dial up.
