How does modem transmit data?
A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a electrical signal that can be transmitted easily and decoded reliably.
Which machine is connected to a telephone through a modem?
A digital subscriber line (DSL) modem is a device used to connect a computer or router to a telephone line which provides the digital subscriber line (DSL) service for connection to the Internet, which is often called DSL broadband.
What kind of data is received by modem?
Short for modulator/demodulator, a modem is a hardware device that allows a computer to send and receive information over telephone lines. When sending a signal, the device converts (“modulates”) digital data to an analog audio signal, and transmits it over a telephone line.
What is a modem in data communication?
Modem is a device that enables a computer to send or receive data over telephone or cable lines. The modulator converts digital data into analog data when the data is being sent by the computer. The demodulator converts analog data signals into digital data when it is being received by the computer.
What is modem in data communication?
Modem. Modem is a device that enables a computer to send or receive data over telephone or cable lines. The modulator converts digital data into analog data when the data is being sent by the computer. The demodulator converts analog data signals into digital data when it is being received by the computer.
What is a modem and its function?
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. Similarly, it converts digital data from a computer or other device into an analog signal that can be sent over standard telephone lines.
What are the functions 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 and its uses?
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. Dial-up modems also required full use of the local telephone line, meaning voice calls would interrupt the Internet connection.
