Computer science, networks: what is a node?
Understanding computer networking leads to self-tutoring: the tutor defines node in computer networks.
node (noun):
an endpoint, or else a directing or processing device between endpoints. The endpoint could be a PC, printer, scanner, server, etc: at an endpoint, content either enters the network or is received there.
The directing device could be a router.
There are different points of view about nodes depending on the type of network, etc. However, one point of view imagines a node as a point where information enters, is received, or is processed in some way to make it available to its end user. A router, for instance, directs information to its various specific requesters.
