Which piece of network equipment extends the cable range and allows connections to be made by increasing the signal strength?

Rationale

Repeater extends the cable range and increases signal strength.

A repeater is designed specifically to amplify signals in a network, effectively extending the distance over which data can be transmitted without loss of quality. By regenerating the signal, it allows devices that are further apart to communicate effectively.

A (Switch) YOUR ANSWER

A switch connects multiple devices within the same local area network (LAN) and manages data traffic between them. While it can help improve network efficiency, it does not amplify or extend the cable range, as it operates at the data link layer and does not alter signal strength.

B (Repeater) CORRECT

A repeater receives an incoming signal and retransmits it at a higher power, which allows the network connection to extend over longer distances. This is critical in maintaining signal integrity in longer cable runs or in environments where signal degradation occurs.

C (Router) YOUR ANSWER

A router connects different networks and directs data packets between them. While routers can manage and direct network traffic, they do not specifically increase signal strength or extend cable range; their primary function is to route data to its destination across networks.

D (Firewall) YOUR ANSWER

A firewall serves as a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It does not play a role in signal amplification or extending cable distance, focusing instead on protecting the network from unauthorized access.

Conclusion

In networking, a repeater is the key device that extends cable ranges and enhances signal strength, making it essential for long-distance communication. Other devices like switches, routers, and firewalls serve different functions related to data management and security, but they do not contribute to signal amplification, which is vital for maintaining effective communication over extended distances.
