1. Short for MODulator/DEModulator, a modem is a hardware device that enables a computer to transmit and receive information over telephone lines. The modem is responsible for converting the digital data used by your computer into an analog signal used on phone lines and then converting it back once received on the other end. To the right is an image of the UsRobotics 56k external Faxmodem, an example of what an external modem looks like.
Because of the speed limitations of modems, many users are upgrading to a broadband connection such as a cable modem or DSL, which offer a faster download and upload speed when compared to the modem.
2. A modem is also used to refer to the hardware device that connects a computer to a broadband network. Often this device is connected to the coaxial or other broadband line and a network cable or USB cable connects that device to the computer. Users may also connect the broadband modem to a router and allow multiple computers to share the connection.
