N

node

A server, controller, workstation, printer, or other processor that implements SNA functions.

SNA defines three kinds of nodes: the host subarea node that controls and manages a network; the communication controller subarea node that routes and controls data flow through the network; and peripheral nodes that include printers, workstations, cluster controllers, and distributed processors.

node type 2.1

An SNA component, such as an intelligent terminal or a PC, that works together with LU type 6.2 to support peer-to-peer communications, allowing the LUs to function independently from the host. This is referred to as a 2.1 node.
