Which two devices are considered intermediary devices in a network?

Intermediary devices are essential components of a network that manage the flow of data between end devices and facilitate communication within the network. The correct response identifies a switch and a modem as intermediary devices.

A switch operates at the data link layer of the OSI model and connects multiple devices within a local area network (LAN). It forwards data packets to the appropriate device based on MAC addresses, effectively managing and directing traffic to ensure efficient communication.

A modem, on the other hand, connects a home or office network to the internet by converting digital data from a computer into an analog signal suitable for transmission over telephone lines or cable systems, and conversely, it converts incoming signals back into digital data. It serves as the gateway between the local network and external networks, such as the internet, and plays a vital role in facilitating connectivity.

In contrast, devices like a PC (which typically serve as end devices) and a server or printer don't manage network traffic; instead, they are primarily involved in producing or consuming data. An access point, while it provides connectivity in a wireless network, and a firewall, which adds a layer of security, also function as intermediary devices, but the choice that includes both a switch and a modem specifically highlights common, foundational intermediary roles
