What does a modem do in a network setup?

Connects computers to a printer Converts digital data to analog for transmission Routes traffic between different networks Secures the network with a firewall

Correct Answer:

Converts digital data to analog for transmission

Explanation:

A modem plays a crucial role in facilitating communication in a network setup by converting digital data into analog signals and vice versa. This conversion is essential because data must often be transmitted over telephone lines, cable systems, or satellite systems, which primarily operate using analog signals. By converting the digital data generated by computers into a form that can be transmitted over these mediums, the modem enables effective communication between devices and the internet or other networks. Once the data reaches its destination, the modem also converts the incoming analog signals back into digital data for use by the receiving device. This dual function of converting signals makes the modem an indispensable component in many network configurations.
