Which component would likely be protected by a surge protector?

Surge protectors are designed to safeguard electronic devices from voltage spikes that can occur due to lightning strikes, power surges, or other electrical anomalies. When considering the components listed in the question, it is essential to recognize that all of them—keyboards, monitors, and routers—are vulnerable to such fluctuations.

Keyboards, while they may not be the most sensitive to voltage changes compared to other devices, can still suffer damage from excess power that could affect their internal circuitry. Monitors, on the other hand, are particularly affected by voltage surges, which can lead to failures in display functionality or complete hardware failure. Routers are crucial for network connectivity; a power surge could not only damage the router itself but also disrupt the network it manages.

By using a surge protector for all these devices, you ensure a comprehensive level of protection against electrical disturbances, making the option that includes all components the most appropriate choice. This holistic protection strategy ensures all connected devices are shielded, reducing the risk of costly repairs or replacements due to surges.
