What Is a Modem in Computer Networking?
History of Modems
The first devices called modems converted digital data for transmission over analog telephone lines.
An external dial-up modem plugs into a computer at one end and a telephone line on the other end.

In the past, some computer makers integrated internal dial-up modems into the computer.
Modern dial-up internet modems transmit data at a maximum rate of 56,000 bits per second.
However, the inherent limitations of public telephone networks often limit modem data rates to 33.6 Kbps or lower.
The router or gateway directs the signal to all the devices in the business or home as needed.
Some broadband routers include an integrated modem as a single hardware unit.
Many broadband internet providers supply suitable modem hardware to their customers at no charge or for a monthly fee.
Today, most modems come with built-in Wi-Fi support.
Today, not much.
Most modern modems and routers share the same functionality.
However, traditionally, a modem handles your connection to the internet.
