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.
What hard ware component modulate and demodulate signals and gives there functions?
The hardware component that modulates and demodulates signals is called a modem (modulator-demodulator). Its primary function is to convert digital data from a computer into an analog signal suitable for transmission over telephone lines or other communication mediums (modulation), and to convert incoming analog signals back into digital data for the computer to process (demodulation). This enables effective communication over various types of networks, including broadband and dial-up connections.
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.
Why must a modem to be used to transmit binary data through a PSTN?
A modem is necessary for transmitting binary data over a Public Switched Telephone Network (PSTN) because it converts digital signals from a computer into analog signals that can travel over the telephone lines. The PSTN is designed for voice communication, which uses analog signals, so the modem acts as a translator between the digital data and the analog format required by the network. Additionally, the modem ensures that the data can be reliably sent and received, handling modulation and demodulation processes effectively.
Input and output of a modem?
A modem (modulator-demodulator) converts digital data from a computer into analog signals for transmission over telephone lines or other communication media (modulation) and vice versa (demodulation). The input of a modem is typically digital data from a device like a computer or router, while the output is an analog signal suitable for transmission. Conversely, the input received by the modem is an analog signal from the communication medium, which it converts back into digital data for the receiving device. This process enables internet connectivity and data communication over various types of networks.
What is a digital telephone?
it is a telephone which is digital and it has a computer inside it
Can you plug a telephone into the telephone port on your computer?
yes
Is a fax machine most like a telephone or a computer?
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.
