What is meant by modulation and demodulation?
The full form of Modem is Modulator-demodulator. Modulation is process of converting the digital computer signals to analog telephone signals. Demodulation is the opposite conversion, analog to digital.
Is the computer is input or output?
modulation and demodulation
Where does the name modem come from?
It is a device that changes the digital signal from a computer into the analogue signal more suited to a phone line, and the analogue signal from phone line into the digital signal for the computer to use. These two processes are called modulation and demodulation. The word modem comes from these two words: MOdulation and DEModulaion = MO DEM.
How does modern work for computer?
you mean modem? MO-DEM MOdulation / DEModulation. It turns your digital signal into analog, so it can go thru the phone lines to your isp, and then from the phone lines to their server, it converts the analog signal back into digital.
How do you connect a telephone to the telephone port on your computer?
To connect a telephone to the telephone port of your computer, use a telephone jack.
What is a digital telephone?

Can you plug a telephone into the telephone port on your computer?

What is the best description of the function of demodulating by a modem?
Demodulation means converting the sounds or signals received by the modem back into data that is usable by the computer.
Is a fax machine most like a telephone or a computer?

What connects the computer to the telephone?
A Bluetooth!!
What device changes digital computer data into analog data that can be sent over phone lines?
A modem performs this function. A modem converts digital information to analog information to transmit a signal over phone lines. The process of converting this signal in this manner is modulation. They also convert analog information back to digital information to receive data. This is called demodulation. The name modem is a combination of the words modulator-demodulator.
