SNMP (Simple Network Management Protocol)
SNMP enables central network management for many network components.
The primary goals of SNMP are reduced complexity of management functions,
the extendability of the protocol and the independence of network components.
SNMP is a standardised network management protocol which can be used to
exchange statistics regardless of platform and set parameters. Elements of a
network (e.g. router, server, switch, printer, computer etc.) can be monitored and
controlled from a central station.
Range of tasks of SNMP:
• Monitoring network components
• Remote control and remote conguration of network components
• Error detection and reporting
SNTP/NTP
This is a software solution which enables the time to be updated. With SNTP one
single time server is used for synchronisation. With NTP several time servers are
used and compared.
NTP uses more resources, but this problem is trivial given the high computing
power of today's machines.
Spanning tree protocol

ST plug
This FO plug specied by AT&T (IEC 61754-2) is suited to both singlemode bres
and multimode bres. The ST plug is a common plug used in LANs.
Star topology
In the star topology, the transmission stations are connected in a star shape
around a central node. Star topologies can only exchange data indirectly via the
central node.
Star-quad cable
A star-quad cable is a symmetrical copper cable whose four wires are stranded
in parallel.
Straight-through
Unlike crossover cables, straight-through cables are patch cables whose transmit
and receive cables are not swapped but are connected 1:1.
Station
Hardware components in a network: connected end device, server, router,
phone, fax machine etc.
