1A point at which lines or pathways intersect or branch; a central or connecting point.
- To the east is Aegidientorplatz, a major node and traffic intersection dominated by an axially placed theatre.
- It provided near-real-time monitoring of the flow of critical classes of supply across critical nodes and lines of communication.
- In a network the decision points are called nodes and the lines connecting nodes are called edges or paths.
1.1 Computing A piece of equipment, such as a PC or peripheral, attached to a network.
- With an Ethernet interface, each cable modem appears as a node on an Ethernet LAN.
- A plurality of computer nodes communicate using seemingly random Internet Protocol source and destination addresses.
- Network nodes can be notebooks, handheld computers or other devices that accept MeshNetworks' communications card.
1.3 Astronomy Either of the two points at which a planet’s orbit intersects the plane of the ecliptic or the celestial equator.
- Lunar eclipses occur at the time of a Full Moon, and when the Moon is near one of the nodes of intersection between its orbit and the ecliptic plane.
- This is because the nodes of the orbit of Venus pass across the Sun in early June at the descending node, and early December at the ascending node.
- If the lunar orbit were fixed in space, such that the nodes occurred always in the same locations, then the Sun would pass through those nodes once per solar year.
1.4(In generative grammar) a vertex or endpoint in a tree diagram.
- Since each node represents an elementary segment (a terminal category), the nodes in a dependency tree are typically labeled by lexemes.
- Each node carries three types of information: a syntactic function, a lexeme and a set of morphosyntactic features introduced by a part of speech category.
- When you ‘read’ a tree, identify constituents by looking at all the elements that are exhaustively dominated by a single node in the tree.
2 Botany The part of a plant stem from which one or more leaves emerge, often forming a slight swelling or knob.
- For each plant, we recorded the number of leaf nodes producing flowers and the total fruit production.
- Each shoot has several leaves arising from nodes located near its tip.
- Both the stems and leaves, which occur in whorls at the node, are covered in hooks; these are thought to aid attachment to their support and allow the plant to climb without twining.
3 Anatomy A lymph node or other structure consisting of a small mass of differentiated tissue.
- Fixed, firm, or matted lymph nodes and nodes larger than 1.5 cm require further evaluation.
- Some of the calcium channel blockers also exert an inhibitory effect on the sinus and atrioventricular nodes, causing the heart rate to slow.
- Computed tomographic scan of the chest and abdomen revealed multiple enlarged nodes in the retroperitoneum, superior mediastinum, and axillae.
4 Physics & Mathematics A point at which the amplitude of vibration in a standing wave system is zero.
- While in St Petersburg he made one of his most famous discoveries when he defined the simple nodes and the frequencies of oscillation of a system.
- Here a beam selectively pushes one size of particles toward a standing light wave, which directs the particles toward its nodes.
Late Middle English (denoting a knotty swelling or a protuberance): from Latin nodus 'knot'.
