Router
Connects neighboring subnets, the router operating with addresses and
protocols of the third ISO/OSI layer. As this layer is hardware independent,
the routers allow transition to another transmission medium.
To transmit a message the router evaluates the logical address (source and
destination address) and finds the best path if there are several possibilities.
Routers can be operated as repeaters or bridges.
Routing
Method of selecting the best path over which to send data to a distant
network.
S
SCADA
Abbreviation for Supervisory Control and Data Acquisition. SCADA
software is a program for the control and visualization of processes.
Segment
Typically, a network is divided up into different physical network segments
by way of routers or repeaters.
Server

SMTP
Short form for „Simple Mail Transfer Protocol". Standard protocol, with
which E-mails are sent away in the internet.
SNMP
Short form for „Simple Network Management Protocol". SNMP serves
remote maintenance of servers. Thus leave themselves e.g. rout directly from
the office of the network carrier out to configure, without someone must
drive for this to the customer.
