From the options below, which suits best for MODEM?

A modem (Modulator-Demodulator) is a device that converts digital data from a computer into a signal that can be transmitted over phone lines, cable systems, or satellite links and then back into digital data that a computer can process. It plays a crucial role in enabling internet connectivity by facilitating the communication between your home network and your internet service provider.

Therefore, from the options typically associated with a modem, the most suitable roles or functions are:

1. Data Conversion: A modem converts digital signals from a computer into analog signals for transmission over traditional phone lines or coaxial cables and then back into digital signals that the computer can understand.

2. Internet Connection: It facilitates the connection to the internet by providing the necessary interface between the computers or local network and the external network (internet).

3. Signal Modulation/Demodulation: This is the primary function of a modem, as indicated by its name (Modulator-Demodulator). It modulates digital signals from the sending machine into a form suitable for transmission over analog communication lines and demodulates incoming signals back into a digital form that the receiving end can interpret.
