Digital modems developed from the need to transmit data for North American air defense during the 1950s. Modems were used to communicate data over the public switched telephone network or PSTN. Analog telephone circuits can only transmit signals that are within the frequency range of voice communication. A modem sends and recieves data between two computers. Modem stands for modulate/demodulate.
In 1962, the first commercial modem was manufactured - the Bell 103 by AT&T. The Bell 103 was also the first modem with full-duplex transmission, frequency-shift keying or FSK, and had a speed of 300 bits per second or 300 bauds.
The 56K modem was invented by Dr. Brent Townshend in 1996.

What does a modem do to enable a ps2 online?
If nothing else is connected to the modem you can use a ethernet cable to connect the ps2 to the modem and the internet. If you also have a PC then you need to put a router between the modem and PC and also connect the PS2 to the router which will allow both the PC and PS3 to work off the same modem
Would it work if you connected an Ethernet cable to a modem and then to a ps3 to play on line?
If for instance you have a PC connected to the internet with an ethernet cable at a cable modem you can unplug the ethernet cable to the PC at the modem and Plug in a ethernet cable from the PS3 to the modem and a connection to the internet is possible. If the PC and PS3 are close enough you can just unplug the PC ethernet cable at the PC and move it over to the PS3. The first time you do this you need to go to the PS3 network setting and auto set the network settings. When you are done using the PlayStation 3 you just unplug the ethernet cable for the PS3 from the modem and plug the PC cable back into the modem for the PC to go back online or switch the cable back if it was close enough. When you get tired of doing this just purchase a router and plug the PS3 and PC into the router and plug the router into the modem.
