Modem (Automotive)

A modulator-demodulator; a device that changes analog signals to digital, and vice versa, for communications.

Modem (Computer)

An abbreviation for modulator-demodulator. A modem is the device that enables a microcomputer or terminal to communicate over a telephone line to another computer or to a computer network. It may require software for it's use.

Modem (Computer Hardware)

It stands for Modulator Demodulator, but it's use is much simpler. It enables a computer to "dial-up" to another computer for a variety of purposes including Fax, Gaming, or Internet connections. There is a large variety of modems available now including the original 14.4, 28.8, 33.6, and 56k modems as well as newer ISDN (128k) and ADSL (256k) modems. To use any modem, your Internet Service Provider must support the format (modem, ISDN, or ADSL). Also, new phone lines are needed for ISDN, and ADSL must have support in your area. Visit the Modem Page for more information and recommendations.

Modem (Computer Technology)

Computers are not capable of communicating over a phone line on their own, because computers communicate in digital signals while telephone lines communicate in analog waves. A device is needed to translate signals from digital to analog and vice-versa. This device is a modem. A sending modem "MOdulates" digital signals into analog ones, while the receiving modem will "DEModulate" analog signals back into digital ones.

Modem (Computer Virus)

A device that enables a computer to transmit information over a standard telephone line. Modems can transmit at different speeds or data transfer rates. See also baud rate, bps.

Modem (DSL)

'MOdulator / DEModulator' - a device for converting between the digital technology required for computers and the analog transmission/reception required for regular telephone lines.

Modem (Digital Imaging)

MOdulate-DEModulate - A device that allows computers and peripherals to communicate over telephone lines.

Modem (Domain Names)

A device that changes computer data into formats that can be more easily transmitted by telephone or other communications link.

Modem (E-Learning)

A device that enables computers to interact with each other via telephone lines by converting digital signals to analog for transmitting and back to digital for receiving.

Modem (Ework)

A device that allows a computer to communicate with another computer by dialing over telephone lines. Modems may be built into compUters or added onto them as separate equipment. To get onto the INTERNET, one's computer must dial an ISP's computer using a modem

Modem (Fax Machines)

A modem is a device that allows computers and other electronic equipment to communicate through ordinary telephone lines.

Modem (Graphics, Hardware)

A computer device used to connect a computer to a telephone line. Once that connection is accomplished, that computer can be used to call any other similarly equipped computer regardless of type. Those two machines can now share information. Modems come in various speeds (fast is good and speed is rated in "baud") but the transfer rate will always be considered too slow for transferring large graphics files. (Overcoming this speed problem is the main reason for file compression software.)

Modem (HDTV)

Modulator/demodulator. A device that transforms a typical two-level computer signal into a form suitable for transmission over a telephone line. Also does the reverse--transforms an encoded signal on a telephone line into a two-level computer signal.

Modem (Ham Radio)

Short for modulator/demodulator. A modem modulates a radio signal to transmit data and demodulates a receive signal to recover transmitted data.

Modem (Health Informatics)

Modulator-demodulator Devic use fo convertin digita signa int tone tha ca b transmitte dow telephon wire.

Modem (Interactive Marketing)

Device which transfers digital signals to analog signals and vice versa suitable for sending across phone or cable lines.

Modem (Internet)

(MOdulator, DEModulator)
A device that connects a computer to a phone line. A telephone for a computer. A modem allows a computer to talk to other computers through the phone system. Basically, modems do for computers what a telephone does for humans.
The maximum practical bandwidth using a modem over regular telephone lines is currently around 57,000 bps.

Modem (Technology)

Short for modulator/demodulator. A communications device that enables a computer to transmit information over a standard telephone line. Because a computer is digital (works with discrete electrical signals representing binary 1 and binary 0) and a telephone line is analog (carries a signal that can have any of a large number of variations), modems are needed to convert digital to analog and vice versa. When transmitting, modems impose (modulate) a computer's digital signals onto a continuous carrier frequency on the telephone line. When receiving, modems sift out (demodulate) the information from the carrier and transfer it in digital form to the computer. Sophisticated modems are also capable of such functions as automatic dialing, answering, and redialing in addition to transmitting and receiving. Without appropriate communications software, however, modems cannot perform any useful work. See also baud rate.

Modem (Telecommunications)

A MOdulator DEModulator computer peripheral which allows a computer to communicate over telephone lines. This is the heart of computer telecommunications. The main factor that differentiates modems is their speed, measured in bps. Analogue modems talk to one another by converting digital info from the computer into tones called PSK’s. An ordinary analogue modem cannot be physically connected to a GSM phone because networks will not carry PSK tones.
