Question 34

Repeater extends the cable range by increasing the signal strength.

A repeater is specifically designed to extend the range of a network by amplifying and regenerating signals, allowing for longer cable runs and improved connectivity.

A) Repeater

A repeater is the correct answer because its primary function is to receive incoming signals, amplify them, and then transmit the strengthened signals further along the network. This capability directly addresses the need for increasing signal strength and extending cable range, making it essential for long-distance communications.

B) Router

A router is not designed to extend cable range; instead, it manages traffic between different networks. While routers can direct data packets and connect multiple devices, they do not amplify signals or extend the physical distance of a network cable.

C) Switch

A switch connects multiple devices within the same network and facilitates communication between them. However, it does not enhance signal strength or extend cable range; its role is more about managing data flow rather than improving signal quality.

D) Firewall

A firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It does not function to amplify signals or extend cable ranges; its purpose is to protect the network from unauthorized access.

Conclusion

The repeater is definitively the correct answer as it is specifically designed to extend cable range by increasing signal strength, a function that none of the other options provide. Routers, switches, and firewalls serve different roles within a network infrastructure, focusing on data management and security rather than signal amplification.
