Routing Information Protocol is an interior or intra-domain routing protocol that uses the
RIP
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.
In NetWare, the SAP (Service Advertising Protocol) broadcasts information about available
SAP
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.
Symmetrical Digital Subscriber Line is a symmetrical, bi-directional DSL service that operates
SDSL
on one twisted-pair wire. It can provide data rates up to the T1 rate of 1.544 Mbits/sec, and it
operates above the voice frequency, so voice and data can be carried on the same wire.
A computer, or a software package, that provides a specific kind of service to client software
Server
running on other computers.
System Network Management Protocol is a popular management protocol defined by the
SNMP
Internet community for TCP/IP networks. It is a communication protocol for collecting
information from devices on the network.
Twisted-pair cable consists of copper-core wires surrounded by an insulator. Two wires are
STP
twisted together to form a pair, and the pair form a balanced circuit. The twisting prevents
interference problems. STP (shielded twisted-pair) provides protection against external
crosstalk.
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar devices, for
Straight
example, a data terminal equipment (DTE) device and a data communications equipment
through
(DCE) device. A straight through Ethernet cable is the most common cable used.

Single User Account – The Prestige's SUA (Single User Account) feature allows multiple user
SUA
Internet access for the cost of a single ISP account - see also NAT.
Transmission Control Protocol handles flow control and packet recovery and IP providing
TCP
basic addressing and packet-forwarding services.
Telnet is the login and terminal emulation protocol common on the Internet and in UNIX
Telnet
environments. It operates over TCP/IP networks. Its primary function is to allow users to log
into remote host systems.
A device that allows you to send commands to a computer somewhere else. At a minimum,
Terminal
this usually means a keyboard and a display screen and some simple circuitry.
Software that pretends to be (emulates) a physical terminal and allows you to type commands
Terminal
to a computer somewhere else.

Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File Transfer
TFTP
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 is a connectionless transport service that dispenses with the reliability services provided
UDP
by TCP. UDP gives applications a direct interface with IP and the ability to address a
