It converts or "modulates" an analog signal from a TELEPHONE or cable wire to digital data (1s and 0s) that a computer can recognize.The types of available modems include analog, digital subscriber line (DSL), cable and Integrated Services Digital Network (ISDN). Analog modems are used for dial-up connections. DSL and cable are high-speed broadband connections. |
