A special point in a graph or diagram which is attached to other points by links. It is often labeled and represented graphically as a box or circle. A node may represent any object which is related to other objects in a conceptual structure that can be represented as a graph, the relations being represented as links between the nodes.

(1) In network topology, the point at the end of a branch. (2) In a tree structure, a point at which subordinate items of data originate. ANSI. See root, tree, child node, parent node. (3) In database management, data that can be accessed by more than one route.

A synonym for vertex. See graph.

A name in a graph. In the CallGrapher, a node represents a function. In the ClassGrapher, a node represents a class.

A variable which denotes a node of the rule test graph

A node represents a piece of data in an organizational tree.

Name for the representative of an entity. See Also Graph. Big-Oh notation. A theoretical measure for the execution of an algorithm. Usually denotes the time (or memory) needed relative to the problem size, i.e., some number of items. The most frequently encountered complexity classes are (where is the number of items): O(1), constant time. Does not depend on the size of the problem, i.e., an operation with O(1) always takes constant time. O(n), linear time. The execution time grows proportional to the size of the problem, i.e., if the problem size doubles, then an operation with O(n) will roughly take twice as long. O(n*n), square time. The execution time grows proportional to the square of the size of the problem, i.e., if the problem size doubles, then an operation with O(n*n) will roughly take four times as long.

A point or vertex on a tree (graph theory); on a phylogenetic tree, a node is commonly used to represent the split of one lineage to form two or more lineages (internal node) or the lineage at the present time (terminal node).

Another word for vertex.

The basic constituent of MDSplus TREES. Nodes come in two basic types; CHILDREN, which embody the structure of the tree and MEMBERS which contain data.

(Engine) A branching of the BSP Tree.

From OWL Web Ontology Language Guide ( 2004-02-10) as in RDF Graphs

In a graph, a node is a representation of an object at the junction of zero or more edges. Opposites: edge. See also: graph.

node is a way of referring to a pair of labelled parentheses when thinking of it in terms of tree structure (a pair of labelled parentheses represents a node in a tree structure); it is often used interchangeably with phrase

Node represents a single step in the Call Tree and stores the questions, responses, and actions that are performed at that step.

In the VxVM tree, a node is an element attached to the tree. In a cluster environment, a node is a host machine in a cluster.

The elementary component from which a FADU tree is built.

A node in a Decision or Classification Tree. A node represents a decision, grouping or condition for further splitting.

An object of a tree structure.

An individual organizational entity on the security tree

in a tree graph, an endpoint of a line segment. See leaf node, branch node.

basic component of a (scene) graph

Internal: connects branches of a tree Terminal: free end of branches representing 'species'

A element in a tree that has connections to one or more lower elements. A parent. See leaf.

b . An occurrence of an element in a tree structure. See: Element, Tree

A point in a graph, usually represented by an ellipse, which represents a specific variable. Some types of nodes are as follows: Child - A node which has an arrow coming into it, from its parent. Deterministic - A node with a value completely specified by the values of its parents, with no uncertainty. Evidence - A node one knows the exact value of, when querying the network for a probability. Leak - A node used to represent miscellaneous causes, known or otherwise. Parent - A node which has an arrow leading out of it, to its child. Query - A node for which one asks the network the probability, given certain evidence.

An individual item on a tree. Nodes summarize detail values or other nodes, and may or may not roll up into other nodes or levels.

The nodes are connected in the graph. A node has an associated operation or can be constructed graph.

A connection point of two or more branches in a graph. In an electrical system, and equipotential surface can be modeled as a node.

a level of hierarchy in the portal. Nodes include pages, labels, or URLs, and are used to navigate the portal structure. The portal has a tree structure that is used to organize the portal into branch nodes, which belong to other nodes that are higher in the tree. The single highest node in the portal is called the content root. Nodes are represented and accessed from the portal navigation menu.

A particular version of the source file*. The name comes from the idea of a Version Tree* with a node of the tree representing a particular version of the file.

The basic element of a binary tree, consisting of a key (see key left child (see left child), and a right child (see right child).

The fundamental component of a scene graph in VRML. Nodes are abstractions of various real-world objects and concepts. Examples include spheres, lights, and material descriptions. Nodes contain fields, and events. Messages are sent between nodes via routes.

A representation of a resource or a literal in a graph form; specifically, a vertex in a directed labeled graph.

A class derived from pfNode. A node can be part of a scene graph.

From information architecture, a branching point in a taxonomic tree, technically referring to an ODP category exclusive of its parent categories or subcategories. However, used less technically as a synonym for a branch category.

Refers to a particular grouping or area of tree. From a conceptual framework, a node would be similar to a branch on a tree. Please see the definition for "Tree" and "Leaf" to further understand how the three components interrelate. Note, all nodes roll-up into their respective parent node and any node is classified as a sibling to the parent node. Furthermore, below or extending from another node is a child of the prior parent node.

In information modeling, "node" is the term given to each unique point in the heirarchical tree outline. The tree that an XML document represents has a number of different types of nodes: * element, * document, * processing instruction, * comment, * data. The root node of an XML document is the document, not the document element An XML document as a linearization of a tree structure. At every node in the tree there are several character strings which may be accessed by identifying the node. See reference node (below) or The XML Data Model at W3C

A single state in a state-space representation. In search, a junction point in the search tree, representing a state which may need to be considered either as a possible solution to a problem or en route to reaching such a solution.

Each entry in a schema tree displayed within BizTalk Editor and BizTalk Mapper. Sometimes called a schema node, but not to be confused with the Schema node, which is the outermost node in all BizTalk schemas.

An element in a hierarchical tree structure. A node may be the root, or the child of another node. A node can also be the parent of multiple children. See also hierarchy, tree, root, child, parent.

In XML, the term used to denote each addressable entity in the DOM tree.

A level within any tree.  Depending upon which tree you are viewing, a node could be a ten-digit "low-level" center, a home department, a sumto home department, or any center group.

n. 1. A junction of some type. 2. In local area networks, a device that is connected to the network and is capable of communicating with other network devices. 3. In tree structures, a location on the tree that can have links to one or more nodes below it. Some authors make a distinction between node and element, with an element being a given data type and a node comprising one or more elements as well as any supporting data structures. See also element (definition 1), graph, pointer (definition 1), queue, stack, tree.

The graphical representation in a phylogenetic tree of an extant or ancestral operational taxonomic unit.

A decision point in a classification (i.e., decision) tree. Also, a point in a neural net that combines input from other nodes and produces an output through application of an activation function.

A node is an abstract basic unit used to build linked data structures, such as linked lists and trees, and computer-based representation of graphs. Nodes contain data and/or links to other nodes. Links between nodes are often implemented by pointers or references.
