A modem is a tool that permits one computer to link up another and transfers data. The word modem is a short for Modulator/ Demodulator. There are mainly two types of modems i.e. hardware and software. The difference between the two is that ‘Hardware modems’ consist of an on-board controller implemented in hardware, whereas the ‘Software modems’ don't contain any hardware controller.
