What is the purpose of a modem is to?
A modem converts a digital signal into an analog signal. Allowing us to use a phone line as a transmission medium.
What are Modems used for in Internet?
Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
What Is a Computer modem made of?
A computer modem is made up of various components including a modulator, demodulator, analog-to-digital converter, digital-to-analog converter, signal processor, and a connection interface such as Ethernet or phone line. These components work together to modulate digital data from the computer into analog signals for transmission over a communication medium and then demodulate received analog signals back into digital data for interpretation by the computer.
How does an external modem work?
An external modem connects to a computer and a communication line, such as a phone line or cable system, to facilitate data transmission. It modulates digital signals from the computer into analog signals for transmission over the communication line and demodulates incoming analog signals back into digital form for the computer. This process allows devices to communicate over long distances by converting data formats suitable for both the digital realm of computers and the analog nature of communication lines. External modems typically connect via USB or serial ports, providing a bridge between the digital and analog worlds.
Define analog signalADSL signaldigital signal?
These are all computer and technology terminology. Analog and digital signals are used for data transmission, and ADSL refers to an Asymmetric Digital Subscriber Line modem.
Piece of equipment that allows a computer to connect to a phone line called?
It's called a Modem which stands for Modulator/Demodulator. Modems take digital signals from the sending computer and convert these signals into Analog so they can be transmitted over wire (phone or cable). On the receiving computer, the Analog signals are then converted back to Digital in order for the computer to decipher the information.
What is an Internet phone?
Internet phone conforms to Internet protocol. Analog phone can work with digital line by connecting a ATA into it. ATA is a connector or device that will convert analog signal to digital signal making standard phone an IP phone.
What is an analog phone line?
It would probably be easiest to give you some examples of an analog line. Usually the phone you have in your house is an analog line. Another example would be a typical fax line. Another example would be the typical line that your computer would use for a dial up connection. Perhaps the debit machine would use an analog line, but some might use a computer connection also. I just read on one web site that if your phone complies with "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. So generally if the phone in your house will work on that line then it is analog, if it won't then likely it is digital. Digital is a line where the voice has been converted to 1's and 0's and the reconverted back to voice at the other end of the line. Digital lines are generally use in business's, although a business might have either digital or analog lines. Notice on this page http:/www.telephonemagic.com/meridian_centrex_phones.htm although all the phones are considered business phones, the digital phones are on the left and and the analog phones are on the right. Then again your cordless phone in your house might be digital from the base to the handset, but still the line is analog.
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.
What are the differences between analog and digital modems?
Analog modems use the telephone cable to send audio signals, which represent 1's and 0's over a connected phone line, using phone voltages. Digital modems use a high frequency signal with the data superimposed on it. They can use the copper phone wires like an antenna. In this way there does not have to be phone connection in use. The phone can be used as well as the signal, if a filter is used to stop interference. Digital modems can also use fibre optic or coaxial cables.
What is a device that allows computers to communicate with one another via telephone or cable lines?
A modem. Modem is short for mudulator/demodulator. Telephone lines use analog signals which your computer cannot interpret. When analog signals reach a modem however, they are converted to digital signals and then passed to the computer. When sending data, this process is reversed.
