  1. In SNA, nodes are end points or junctions, and data links are the pathways between them. Data links include high-speed local channels, the SDLC data link protocol, Token Ring and Ethernet.

    Nodes are defined as Type 5 (hosts), Type 4 (communications controllers) and Type 2 (peripheral; terminals, PCs and midrange computers). Type 2.0 nodes communicate only with the host, and Type 2.1 nodes communicate with other 2.1 nodes (peer-to-peer) without going to the host.
