NetBEUI (NetBIOS Extended User Interface) - NetBEUI is the network transport
protocol used by all of Microsoft network systems and IBM LAN Server based
systems.
Parity - Parity is an extra bit added to a byte or word to reveal errors in storage (in
RAM or disk) or transmission. Even/odd parity means that the parity bit is set so
that there are an even/odd number of one bits in the word, including the parity
bit. Odd parity means that the parity bit is set so that there are an odd number of
one bits in the word, including the parity bit.
PPP (Point to Point Protocol) - PPP is the protocol defined in RFC 1661, the
Internet standard for transmitting network layer datagrams (e.g., IP packets) over
serial point-to-point links.
PPP is designed to operate both over asynchronous connections and bit-oriented
synchronous systems, it can configure connections to a remote network
dynamically, and test that the link is usable. PPP can be configured to encapsulate
different network layer protocols (such as IP, IPX, or AppleTalk) by using the
appropriate network.
Protocol - A protocol is a set of formal rules describing how to transmit data across
a network. Low level protocols define the electrical and physical standards to be
observed, bit- and byte-ordering, and the transmission, error detection and
correction of the bit stream. High level protocols deal with the data formatting,
including the syntax of messages, the terminal to computer dialogue, character
sets, sequencing of messages, etc.
PSTN (Public Switched Telephone Network) - PSTN is the collection of
interconnected systems operated by the various telephone companies and
administrations (PTTs) around the world.
RFC (Request for Comment) - RFC is a numbered Internet informational
documents and standards widely followed by commercial software and freeware
in the Internet and UNIX communities.
RIP (Routing Information Protocol) - RIP is the companion protocol to IPX for
exchange of routing information in a Novell network. It is not related to the
Internet protocol of the same name.
SAP - SAP is the OSI term for the component of a network address that identifies
the individual application on a host which is sending or receiving a packet.
SHDSL is an international standard for symmetric DSL, developed by the ITU
(G.991.2). It provides for sending and receiving high-speed symmetrical data
streams over a single pair of copper wire, at rates between 192 kbps and
2.31 Mbps. SHDSL incorporates features of other DSL technologies, such as ADSL,
SDSL, and will transport T1, E1, ATM, and IP signals.
SNMP (Simple Network Management Protocol) - SNMP is the Internet standard
protocol, defined in STD 15, RFC 1157, developed to manage nodes on an IP
network.
SOCKS - SOCKS is a security package that allows a host behind a firewall to use
Finger, FTP, Telnet, Gopher, and Mosaic to access resources outside the firewall
while maintaining the security requirements.
