Questions tagged [nodes]

Nodes are the basic units used to build data structures such as linked lists and trees.

A node is a record consisting of one or more fields that are links to other nodes, and a data field. The link and data fields are often implemented by pointers or references although it is also quite common for the data to be embedded directly in the node.

Nodes are used to build linked data structures such as , , and . Large and complex data structures can be formed from groups of interlinked nodes. Nodes are conceptually similar to vertices, which are elements of a graph. Software is said to have a node graph architecture when its organization consists of interlinked nodes.
