Modem Introduction: a device that allows a computer or terminal to transmit data over a standard telephone line, or internal electronic circuitry used to transmit and receive digital data over a communications line normally used for analog signals. Synchronous data transmission uses timing signals in the data stream along with transmitted bits of uniform duration and interval. Asynchronous data transmission relies instead on various error-correcting protocols. Wireless modems send or receive data as a radio signal. A fax modem enables a computer to send and receive transmissions to and from a fax machine..

This page highlights pre-qualified Modems manufacturers, exporters and suppliers in China and around the world, which is broadcasted online by the world Suppliers Directory. the sophisticated B2B directory covering useful Modems Business information and Modems trade services displayed to its full extent by product description and manufacturer background introductions.
