What is the key function of a line extender in a network?

1. Improving data encryption

2. Extending the signal within the network

3. Managing user bandwidth

4. Securing connections

The correct answer is: Extending the signal within the network

The key function of a line extender in a network is to extend the signal, allowing it to cover a larger area or reach devices that are further away from the network's main connection point. This is particularly important in environments where physical obstacles or long distances can weaken or degrade the signal of the original network connection. Line extenders work by receiving the existing signal, amplifying it, and then retransmitting it further along the connection. This capability ensures that network performance remains high even in larger or more complex setups, providing users with reliable access to network resources regardless of their location within the coverage area. While improving data encryption, managing user bandwidth, and securing connections are important aspects of network management and security, they are not functions served by line extenders specifically. Line extenders focus primarily on enhancing the reach and strength of the network signal itself.
