What do you mean by modem?

Modem, (from “modulator/demodulator”), any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.

HOW DO modems convert signals?

A modem attached to a computer converts digital data to an analog signal that it uses to modulate a carrier frequency. This frequency is transmitted over a line, frequently as an audio signal over a telecommunications line, to another modem that converts it back into a copy of the original data.

What is a modem and its function?

A modulator-demodulator, or simply a modem, is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.

What is output signal of digital modems?

DAC. Devices process digital data and create digital output as well. When a device needs to send out information to another network, this data must be converted into an analog signal in order to be transmitted through the existing connections.

What is a modem very short answer?

Modem is short for “Modulator-Demodulator.” It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. It converts or “modulates” an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize.

What is modem very short answer?

What is main function of modem?

The word “modem” is derived from the term “modulator-demodulator.” The essential functions of a modem are to modulate an analog carrier signal to carry digital information; and to demodulate a similar signal so as to decode the digital information from the analog carrier signal.

What is modem example?

Modem is defined as an abbreviation for modulator-demodulator, a device that makes it possible for computers to communicate with one another without being directly connected to each other. An example of a modem is the device used for a computer to communicate with a satellite.

What are the two types of modem?

There are three types of modems: cable, digital subscriber line (DSL) and dial-up. A cable modem uses coaxial cables that connect to the back of the modem and the bolt-like outlet in your wall or on your cable box. This type of modem delivers high speed internet to your device.

Is modem an output device?

A Modem is considered an input and output device because it sends data (upload/output) and receives data (download/input).

What is modem and its types?

1. A modem or broadband modem is a hardware device that connects a computer or router to a broadband network. For example, a cable modem and DSL modem are two examples of these types of Modems. Similarly, when an analog signal is received, the modem converts it back (“demodulates” it) to a digital signal.

Which is the correct definition of a modem?

A modem may refer to any of the following: 1.A modem or broadband modem is a hardware device that connects a computer or router to a broadband network. 2. Short for modulator/demodulator, a modem is a hardware device that allows a computer to send and receive information over telephone lines.

How does a modem convert an analog signal to a digital signal?

When sending a signal, the device converts (“modulates”) digital data to an analog audio signal, and transmits it over a telephone line. Similarly, when an analog signal is received, the modem converts it back (“demodulates” it) to a digital signal.

What’s the difference between a dial up modem and a DSL modem?

Dial-up Modem: This type of modem are using the analog telephone line to connect two end devices like two personal computer. It offers an interface between the digital system and an analog system. It modulates the binary data into the carrier signal on the telephone line. DSL Modem: DSL model uses twisted pair cable for transmission of signals.

What makes a modem an input and output device?
