node

Imagine a spiderweb: each place where the strands meet is a node. That image helps with the usual meaning. In a network, a node is a point where things connect. It could be a computer in a computer network, a city on a rail map, or a person in a social network. It is a place or point where parts of a larger system meet and link to each other.

The word is often used when people talk about systems, maps, or groups. Sometimes the point is physical, and sometimes it is not. What matters is the idea of connection. A node helps hold the whole structure together.

A node is a point of connection inside a larger system. The idea is simple: it is a place where lines, paths, or relationships meet. People often use the word when talking about networks, because networks are made of many connected points working together.

In technology, a node can be a device connected to a network, such as a computer, server, router, or printer. Each one is part of the system and can send, receive, or pass along information. If you picture the internet or a local office network, you can think of it as a web made of many connected nodes.

The word is also used outside technology. In transport, a station or city can be a node in a travel network. In social network analysis, a person can be a node linked to other people. In biology, the word can refer to a lymph node or to a point on a plant stem where leaves or branches grow. In mathematics and similar fields, it can mean a point where lines or curves meet or cross.

Across these uses, the core meaning stays the same. A node is an important point within a structure because it connects to other points. Sometimes it carries information, sometimes it marks a meeting place, and sometimes it helps organize the whole system. In every case, the word suggests connection, structure, and the role of one point within a larger whole.
