(terminal server).

SNA:
Systems Network Architecture. IBM's layered protocols for mainframe communications.
SNMP:
Simple Network Management Protocol, allows a TCP/IP host running an SNMP application to query

network nodes.
Source Code:
Programs in an uncompiled or unassembled form.
Spanning Tree:
An algorithm used by bridges to create a logical topology that connects all network segments, and
ensures that only one path exists between any two stations.
