Word	Description / Examples
node	Used in technical and scientific contexts, particularly in computer science and networking. It refers to connection points in a network or structure. Each computer in the network is considered a node. The tree diagram consists of several nodes connected by edges.
vertex	Used mainly in mathematical and geometric contexts to refer to a corner or a point where two or more lines, edges, or surfaces meet. A triangle has three vertices. We calculated the angle at the vertex of the polygon.
element	Used when referring to a basic or essential part of a larger system or compound, particularly in chemistry, mathematics, and general language. Hydrogen is the lightest element on the periodic table. An effective presentation contains several key elements.
point	Used to indicate a specific location, place, or moment in time. Can be used in geographical contexts, conversations, and temporal contexts. We met at the meeting point in the park. At this point, we should reassess our strategy.

Examples of usage

A linked list consists of nodes where each node points to the next node in the sequence.
In a binary tree, each node has at most two child nodes.

^{Context #2 | Noun}

networking

In networking, a node refers to any device that is part of a network, such as a computer, server, router, or switch. Nodes communicate with each other to send and receive data across the network.

Synonyms

device, host, terminal.

Word	Description / Examples
node	Use 'node' when referring to a point of connection in a network or a system, such as in computing or biological contexts. It often implies interconnectedness and communication. Each node in the network is responsible for routing data. The tree has multiple branches, each serving as a node.
device	Use 'device' when referring to an individual piece of electronic equipment designed for a specific function. It is commonly used in everyday contexts involving gadgets and tools. Please ensure that your device is connected to the internet. This device measures your heart rate and sends the data to your phone.
host	Use 'host' when referring to a computer system or server that provides data or services to other machines on a network. It can also be used in a biological context to describe an organism harboring another. The website is stored on a remote host server. In biology, a host organism can be infected by a virus.
terminal	Use 'terminal' when referring to an endpoint for data input and output in computing. It is often associated with command-line interfaces or points of connection in a transportation system. Open the terminal window to run the script. The bus terminal is where all the routes converge.

Examples of usage

Each node in the network has a unique IP address.
The router acts as a central node in the network.

^{Context #3 | Noun}

astronomy

In astronomy, a node is a point where the orbit of a celestial body intersects a reference plane, such as the plane of the Earth's orbit around the Sun. There are two types of nodes: ascending node and descending node.

Synonyms

crossing, intersection, point.

Word	Description / Examples
node	Typically used in technical or scientific contexts to refer to a connection point in a network or a specific point in a mathematical diagram. Each node in the network is connected to multiple other nodes. In the diagram, the node represents the starting point.
intersection	Commonly used in urban planning and navigation to refer to the point where two or more roads or streets meet. Traffic lights were installed at the busy intersection. The gas station is located near the intersection of Main Street and First Avenue.
crossing	Often used to describe a place where paths, roads, or tracks intersect, especially in a transit or transportation setting. The pedestrian crossing is just ahead. Be cautious while driving through the railroad crossing.
point	Used broadly in various contexts to refer to a specific spot, location, or moment in time; it can also indicate a particular idea or argument in discussions. We can meet at the starting point of the trail. You made a very good point during the discussion.

Examples of usage

The ascending node is where the orbit crosses the reference plane from below.
The descending node is where the orbit crosses the reference plane from above.
