however, through subsequent RFCs.
RIP
Routing Information Protocol is an interior or intra-domain routing protocol that uses the
distance-vector routing algorithms. RIP is used on the Internet and is common in the NetWare
environment as a method for exchanging routing information between routers.
SAP
In NetWare, the SAP (Service Advertising Protocol) broadcasts information about available
services on the network that other network devices can listen to. A server sends out SAP
messages every 60 seconds. A server also sends out SAP messages to inform other devices that
it is closing down. Workstations use SAP to find services they need on the network.
Server
A computer, or a software package, that provides a specific kind of service to client software
running on other computers.
SNMP
System Network Management Protocol is a popular management protocol defined by the
Internet community for TCP/IP networks. It is a communication protocol for collecting
information from devices on the network.
STP
Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator. Two
wires are twisted together to form a pair; the pair form a balanced circuit. The twisting prevents
interference problems STP provides protection against external crosstalk.
Straight
Through
Ethernet Cable
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar devices, for
example, a data terminal equipment (DTE) and a data communications equipment (DCE) device.
A straight through Ethernet cable is the most common cable used.
SUA
Single User Account. The Prestige's SUA feature allows multiple user Internet access for the
cost of a single ISP account - see also NAT.
TCP
Transmission Control Protocol handles flow control, packet recovery and IPs that providing
basic addressing and packet-forwarding services.
Telnet
Telnet is the login and terminal emulation protocol common on the Internet and in UNIX
environments. It operates over TCP/IP networks. Its primary function is to allow users to log
into remote host systems.
Terminal
A device that allows you to send commands to a computer somewhere else. At a minimum, this
usually means a keyboard and a display screen and some simple circuitry.
Terminal
Software
Software that pretends to be (emulates) a physical terminal and allows you to type commands to
a computer somewhere else.
TFTP
Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File Transfer
Protocol), but it is scaled back in functionality so that it requires fewer resources to run. TFTP
uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol).
UDP
User Datagram Protocol. DP is a connectionless transport service that dispenses with the
reliability services provided by TCP. UDP gives applications a direct interface with IP and the
ability to address a particular application process running on a host via a port number without
setting up a connection session.
