Which of the following is NOT an internet hardware component?

The chosen answer identifies a device that primarily functions as a security measure rather than as an integral part of the data transmission infrastructure typically categorized as “internet hardware components.” Routers, switches, and repeaters are all essential in directing, managing, and amplifying data traffic over a network.

While routers direct data packets between different networks, switches operate within a single network to connect devices and manage data traffic efficiently. Repeaters extend the range of the network by amplifying signals to maintain data integrity over longer distances.

On the other hand, a firewall primarily serves to protect a network by monitoring and controlling incoming and outgoing traffic based on predetermined security rules. This emphasizes its role in security rather than in the direct routing or handling of data, differentiating it from other hardware components that are fundamentally involved in the processing and transmission of data over the internet.
