Node(Latin nodus ‘knot’) is critical element of any computer network.
Definition
A point in a network at which lines intersect or branch. A device attached to a network.[1] A terminal or other point in a computer network where a message can be created, received, or transmitted[2]
Example's
A node is any device connected to a computer network. Nodes can be computers, personal digital assistants (PDAs), cell phones, or various other network appliances. On an IP network, a node is any device with an IP address.[3]If the node is a computer it is more often called a "host".
In Network
A node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.
If the network in question is the Internet, every node must have a MAC address or Data Link Control address[4] if it is at least an OSI model layer 2 device
If the network in question is a peer-to-peer or overlay network, nodes that actively route data for the other networked devices as well as themselves are called supernodes.
Network node (NN)
A grouping of one or more network elements (at one or more sites) which provides network related functions, and is administered as a single entity. A single site may contain more than one network node. For the purpose of this glossary, a network node is considered synonymous with a network element, and is usually at a single site. This restriction simplifies the definition of the network node interface (NNI) and INI, which would not apply between network elements.
In general terms
A node is a specific location in a telecommunication network. In Cable TV systems (CATV), this term has assumed a broader context and is generally associated with a Fiber Optic Node. A fiber optic node is those homes or businesses within a specific geographic area that are served from a common fiber optic receiver. A fiber optic node is generally described in terms of the number of Homes Passed that are served by that specific fiber node.
