A network is fundamentally composed of various devices that facilitate communication and data transfer. Routers, switches, and modems each play a crucial role in this process.

Routers are responsible for directing data packets between different networks, ensuring that information reaches its intended destination efficiently. Switches operate within a single network, connecting devices and managing the flow of data among them. Modems serve as the gateway between the internal network and the internet, converting digital data from a computer to analog for transmission over phone lines (or vice versa).

Servers, while essential for various services and applications that run within a network, are not fundamental components of the network architecture itself. They perform specific functions such as hosting websites or managing resources, but they do not play a direct role in the connectivity or data transfer processes that form the backbone of the network infrastructure. Thus, the focus on routers, switches, and modems as critical network components highlights how they contribute to the fundamental functionality and operation of a network.
