Modems (MOdulator/DEModulator) connect digital equipment to a telephone line. It connects digital equipment to a speech bandwidth-limited communications channel. Typically, modems are used on telephone lines, which have a bandwidth of between 400 Hz and 3.4 kHz. If digital pulses were applied directly to these lines, they would end up severely distorted.
