What is modem explain its types and characteristics?

Modem stands for Modulator and Demodulator. It is a device that modulates signals to encode digital information for transmission and demodulates signals to decode the transmitted information. A modem transmits data in bits per second (bps). It is necessary for communication between digital devices and Analog devices.

What are the characteristics of modem How does it work?

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 signal that can be transmitted easily and decoded reliably.

What are the functions of modem?

A modem transforms digital information from your computer into analog signals that can transmit over wires (and vice versa) by modulating and demodulating electrical impulses sent through phone lines, coaxial cables, or other types of wiring.

What are the classification of modems?

Modems are classified by the amount of data they can send in a given time, normally measured in bits per second (bit/s, or bps). They are also classified by their connection method. Dial-up modems were the usual kind in the 20th century, and DSL modems and Cable TV modems are now more used.
