What Is A Modem And What Does It Do?
HTML-код
- Опубликовано: 22 фев 2024
- A modem is a very important piece of network hardware that allows a computer to send and receive data through a telephone line or cable connection. In simple words, it’s the device that connects a computer to the Internet.
The word modem is actually made by combining parts of two different words - Modulator and demodulator. As this suggests, a modem is a device that both modulates and demodulates signals that encode and retrieve information, respectively. For starters, modulation is a process of adding meaningful information to a carrier wave so that it can be transmitted over long distances.
It should be noted that if you intend to connect to the Internet wirelessly, or want to get multiple devices connected to the same network, a simple modem won’t be enough. In that case, you will need a different device called a router.
