A network node is a fundamental component of any computer network. It can be defined as any active electronic device that is capable of sending, receiving, or forwarding information over a network. Essentially, it is a point of connection or distribution within a network.

Examples of network nodes are diverse and include computers, servers, routers, switches, modems, and even printers or mobile devices when they are connected to a network. Each node has a unique address, such as an IP address or a MAC address, which allows it to be identified and communicated with within the network.

The primary function of a network node is to participate in the communication process. It receives data packets, processes them, and then either acts upon them or forwards them to another node. The interaction between nodes, governed by various network protocols, enables the exchange of data and resources, forming the backbone of modern communication systems. The health and performance of individual nodes can significantly impact the overall efficiency and reliability of the entire network.
