1) The endpoint of a network
connection or a junction common to two or more lines in a network. Nodes can be
processors, controllers, or workstations. Nodes, which vary in routing and
other functional capabilities, can be interconnected by links, and serve as
control points in the network. Node is sometimes used generically to refer to
any entity that can access a network, and is frequently used interchangeably
with device. See also host.
2) In Systems Network Architecture
(SNA), the basic component of a network, and the point at which one or more
functional units connect channels or data circuits.
