Source Routing IEEE standard for 802.5 Token Ring environments from an IBM
development. A workstation (source) determines the router through the LAN
internetwork. It sends a "discovery" or explorer packet along all active paths in the
network, eventually reaching the destination host. Once received, the packet is sent
back to the originator. Along the way, each bridge traversed adds its designator to
the discovery packet. When it arrives at the originator, it contains complete routing
information and the originator can send its data with that information attached. SR-
compliant bridges generally need less processing power since most of the work is
done by the originating workstation. A liability of SR is that the number of discovery
packets traversing the network increases dramatically as the number of Token Ring
LAN segments and internetworking devices between the stations grows.
Spool (Simultaneous Peripheral Operation On Line) A program or device that controls
the flow of data to an outputting device such as a printer. Spooling means that a user
can send data to a device which is already occupied and can rest assured that the
data will be passed onto the desired destination as soon as possible. Spooling of
printer output is achieved on a LAN by means of a print server. It is also important in
WANs for providing a buffer for time savings.
SQL (Structured Query Language) A standardized query language that can be used
for querying databases across a network in client/server applications. It can be used
to interrogate the database, and extension to the language allow the database to be
updated through it as well.
Standalone server In LAN Manager terminology, a server that maintains its own
user accounts database and does not participate in logon security.
Star Topology A network layout or design in which each node is connected to a
central hub. The hub establishes, maintains and terminates all connections between
the nodes. In a LAN, the hub is likely to be a workstation, whereas in larger multi-
point networks the hub is more likely to a multiplexer.
StreetTalk Banyan Systems' directory system which provides a distributed database
of names addresses accessible from Vines.
Storage Media The physical device itself, onto which data is recorded. Magnetic
discs and tape, optical discs, floppy disks are all storage media.
