A modem device is a modulator/demodulator which enables computers to communicate and transmit information through standard analog telephone lines. It converts computer digital information from the outgoing modem through telephone lines which translate the digital data into audio signals. The receiving modem will then change the analog signal back into digital code which gets received by the computer. Accessing the internet is done when your modem dials a phone number which then connects the computer
