What is modem ?

Answer 1

Short for modulator/demodulator. A communications device that converts one form of a signal to another that is suitable for transmission over communication circuits, typically from digital to analog and then from analog to digital.

A device (modulator/demodulator) that allows computer information to be sent over a telephone line.

It usually is used with broadband internet connections. A modem is not needed with dial-up.

Answer 2

Modem is the contraption that is between your computer and whatever type of system you are using to get on the internet. Old modems, like some today, could be inside the computer and were slow comparitively speaking. Some people still use 54k, I think they're called, and it uses the phone line. I use DSL, which has a better modem, but still uses the phone line which restricts speed a little. Cable modem uses cable, so it can go faster.

Answer 3

Short for "modulator, demodulator". It's needed at both ends of a data communication line or channel to convert the source computer data into a form suitable for transmission over the communication channel. The computer data modulates a communication carrier typically that is subsequently demodulated and returned to the original baseband data at the other end of the channel. An example is a dial up modem for telephone line access to your Internet Service Provider (ISP), but other modems can be online continuously like your cable modem. Satellite data links require Radio Frequency (RF) modems to modulate and demodulate data over the microwave carrier frequencies. So the modem carrier frequency can vary from very low frequencies like used in a dial up telephone line all the way up through microwave RF frequencies and on to laser and fiber optic light frequencies.

Answer 4

modulator demodulator -- communications device, an item used in the old days to communicate with an isp to get on the internet typically has speeds of 56kbps.

Okay I know that there are dsl and cable modems. cable modems are actually routers as there is a digital signal going accross the line but dsl modems do modulate and demodulate.

Answer 5

A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

Answer 6

A modem?! its a part to a computer

Answer 7

The word "modem" is short for "modulater/demodulator." Basically, it is your computer's "telephone", which allows it to talk to other computers on the Internet.

Answer 8

A hardware that converts digital data to analog and vice versa to allow communication to the network.

Answer 9

Comm device

Answer 10

it is type of machine with which the internet as well as the comp works!!!!!!!!!!!!!!! it is the modem
