What is the main purpose of a Modem in a computer network?

Detailed Solution for Test: Internet and Networking- 1 - Question 1
A modem, short for Modulator-Demodulator, is a device used to convert digital data from a computer into analog form for transmission over analog networks like telephone lines. It also converts incoming analog signals back into digital data that a computer can understand. This conversion is necessary because computers use digital data, while older networks often used analog signals. Therefore, the main purpose of a modem is to enable communication between digital computers and analog networks.
