What serves the same function for your telephone line to your modem that a surge suppressor does for the electrical lines?
Data line protectors
What device allows data to be sent from computer to computer over a telephone line?
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.
Why a pair of modems is required to transmit the digital signals over a long telephone wire Why not a single modem?
first modem will be modulating electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone line and demodulated by another modem at the receiver side to recover the digital data.
What device links a computer to a telephone line?
A modem.
What portion of the telephone network still depends on analog signals?
Analog data transmissions occurs every time you log onto the internet using your pc, your modem, and your telephone line.
Why modem has speed only 56kbps?
It has to do with a few issues, one of which is the SNR and signal clarity that can be acheived by sending tones down a plain old telephone line. There is just not enough bandwidth in a POTS connection to support higher rates of data flow as well.
Which telephone line is used in most homes?
Modem Cable
What is the hardware component that links the computer to the telephone line?
A modem
Does the internet speed come from a modem or from the company?
The modem will define the speed at which your will be able to access the internet connection. For example, if you have an ADSL modem, you will only be able to access speed at the modem max of 512k even though your telephone line has speeds up to 24,000k. Conversely, if your telephone line is only able to handle speeds upto 512k, having an ADSL2+ modem will not increase your speed. The technology for data transfer speed is in the cable sending and receiving data thus copper cables will be slower then fiber optics. A dial-up modem using the telephone line on analogue (instead of digital) will only transfer at a speed of 64k even though it is using the same copper cable capable of 512k.
Which device connects a computer with a telephone line by providing modulation and demodulation of incoming and outgoing data?
Answer:It's the modem that connects it... It is mainly a combined device for modulation and demodulation. A.K.A digital data of a computer. That is all it is. :D
What is require to connect system to telephone line?
A modulator demodulator (MODEM)
What is the purpose of a laptop modem?
The purpose of the modem is to modulate and demodulate the electonic analog pulses of the computer to pulses the phone system can handle.Modem is used to connect one or more devices. It is also used to connect internet.the full form of modem is modulator demodulator.
