P314 Broadband Sharing Gateway with 4-Port Switch
Glossary of Terms M
Router A device that connects two networks together. Routers monitor, direct, and filter
information that passes between these networks. Because of their location, routers are
a good place to install traffic or mail filters. Routers are also prone to attacks because
they contain a great deal of information about a network.
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.
SOCKS A protocol that handles TCP traffic through proxy servers.
SSL (Secured
Socket Layer)
Technology that allows you to send information that only the server can read. SSL
allows servers and browsers to encrypt data as they communicate with each other.
This makes it very difficult for third parties to understand the communications.
STP
Twisted-pair cable consists of copper-core wires surrounded by an insulator. Two
wires are 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.
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) device 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 (Single User Account) feature allows
multiple user Internet access for the cost of a single ISP account - see also NAT.
TCP
Transmission Control Protocol handles flow control and packet recovery and IP
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
UDP is a connectionless transport service that dispenses with the reliability services
