Server
A computer in a network that is shared by multiple end
stations. Servers provide end stations with access to
shared network services such as computer files and
printer queues.
SFP
Small Form Factor Pluggable (SFP) Connectors are based
on an open standard that enables hot swapping of
various type of fiber optic and copper-based transceivers
into the host equipment.
Subnet Address
An extension of the IP addressing scheme that allows a
site to use a single IP network address for multiple
physical networks.
Subnet Mask
A subnet mask, which may be a part of the TCP/IP
information provided by your ISP, is a set of four
numbers configured like an IP address. It is used to
create IP address numbers used only within a particular
network (as opposed to valid IP address numbers
recognized by the Internet, which must assigned by
InterNIC).
Subnets
A network that is a component of a larger network.
Switch
A device that interconnects several LANs to form a
single logical LAN that comprises of several LAN
segments. Switches are similar to bridges, in that they
connect LANs of a different type; however they connect
more LANs than a bridge and are generally more
sophisticated.
TCP/IP
Transmission Control Protocol/Internet Protocol.
This is the name for two of the most well-known
protocols developed for the interconnection of
networks. Originally a UNIX standard, TCP/IP is now
supported on almost all platforms, and is the protocol
of the Internet.
TCP relates to the content of the data travelling through
a network — ensuring that the information sent arrives
in one piece when it reaches its destination. IP relates to
the address of the end station to which data is being
sent, as well as the address of the destination network.
Traffic Monitoring
Enables the monitoring of port traffic by attaching a
network analyzer to one switch port, in order to
monitor the traffic of other ports on the Switch.
Trunking
A method which specifies how to create a single
high-speed logical link that combines several
lower-speed physical links.
