You've answered your own question. The device is called a Modem (Modulator demodulator).Some computers needed a separate device, later ones had the modem built in and only needed a telephone cord, between the computer and the phone socket.These days broadband is used. The computer's Local Area Network (LAN) socket is connected through a device called an ADSL (Asynchros Digital Subscriber Line) Router.This needs to connect through a filter to the telephone line, to stop interference on the telephone, which can be used at the same time.
A modem allows data to be transferred over a telephone line. It is a combination of MOdulate - DEModulate. One device modulates a digital signal from the computer into an analog signal for the telephone line, then the other device demodulates the signal back into digital for the receiving computer.
Radio shack sells a device that will record when the phone is answered, unbeknownst to either party, as long as the device is hidden.
Fax machines are used to send paper documents to another fax machine user via a telephone line.
Also called as facsimile, fax is a document sent or transfered through a telephone line. Today, fax has upgraded tp internet fax where documents can be sent and received simultaneously.
Both telephone and data signals can be received at the same time by use of a microfilter. This device increases the data-carrying capacity of the line without disturbing the telephone signals.
