Which two devices are classified as intermediary devices?

The classification of devices into intermediary and end devices is essential in understanding their roles within a network. Intermediary devices are responsible for directing data traffic and ensuring that data packets are correctly routed to their destinations, which distinguishes them from end devices that serve as the starting or ending points of communication on the network.

A router is one of the key intermediary devices as it connects multiple networks together, routing data between them based on the IP addresses of the packets. It determines the most efficient path for data to travel across interconnected networks, making it indispensable for directing traffic on large-scale networks, such as the internet.

Switches also fall into the category of intermediary devices, functioning primarily within local area networks (LANs). They forward data frames between devices on the same network, managing data flows efficiently to prevent collisions and ensure that data reaches its intended target.

Firewalls, while critical for network security, are also classified as intermediary devices because they monitor and control incoming and outgoing traffic based on predetermined security rules, but this specific choice wasn't highlighted in the response.

Modems, on the other hand, serve as a bridge between an internal network and an external service provider (like the internet) but do not direct data or manage traffic in between networks, making them
