Answer 1

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

Answer 2

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.

Tip: Today, a "modem" is most often used to describe a broadband modem. However, can also be used to describe what was initially considered a modem (described below) and is also used to connect to the Internet.

Note: A broadband modem is an externaldevice that connects to your computers and other network devices using either a network cable or over a wireless connection.

 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. Similarly, when an analog signal is received, the modem converts it back ("demodulates" it) to a digital signal.

Tip: To help prevent confusion between a broadband modem, you can refer to this modem as a dial-up modem.
