Everything about Node Networking totally explained
A
node (
Latin nodus, ‘knot’) is a critical element of any
computer network. It can be defined as a point in a network at which lines intersect or branch, a device attached to a network, or a terminal or other point in a computer network where messages can be created, received, or transmitted.
A node can be any device connected to a
computer network. Nodes can be computers,
personal digital assistants (PDAs),
cell phones,
switches,
routers or various other networked devices.
Role of nodes in networking
A node is a connection point, either a
redistribution point or an
end point, for
data transmission. 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 if it's at least a
data link layer device, as defined in the
OSI model.
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.
In
telecommunications, a node is a specific location in a
telecommunication network. In
cable television systems (CATV), this term has assumed a broader context and is generally associated with a
fiber optic node. This can be defined as 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.
