Node (computer Science)

Node (computer Science)

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, often hierarchical, data structures such as linked lists, trees, and graphs. 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.
