how does telephone wires able to accomodate internet connections?

Question

i hope am understood with the question.

can you explain it interms of frequency range. how can voice calls be taken while the same time being online.

Answer 1

We communicate over the phone wires using certain sound tones. There are standards that use a combination of sounds to represent each character that gets sent. A special machine called a MODEM (Modulator/Demodulator) makes the conversion from computer characters to the sounds and then later, the conversion is made the other way

Answer 2

Telephone wires weren't originally designed to carry digital data. In order for digital info to be transmitted on telephone wires, the signal must be modulated at the transmitters side, this sends the info as an analog signal in the form of audio tones. At the receiver the signal must be demodulated to get the digital data signal back. Hence modem (modulator/demodulator).

Answer 3

As rightly pointed out above, a modem is used to communicate over the internet. The reason for the phone data and internet data not colliding is that they travel at different frequencies. Or different wavelengths. Two signals traveling at different wavelengths do not overlap and hence the data does not get garbled.
