nodes

In general, a node is a point or connection within a larger system. In technology, such as computer networks, a node can be a device like a computer or phone that sends, receives, or forwards data. In other contexts, like trees in data structures, a node represents a single element or point that connects to others, helping organize information. Think of nodes as key points that hold or transfer information within a network or system, enabling communication or structure. They are essential components that facilitate connectivity and organization in many complex systems.
