PVC

RBOC

Permanent Virtual Circuit. A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or torn down for each session.

(Regional Bell Operating Company): There are currently seven regional telephone companies that were created by the AT& T divestiture.

RFC	An RFC (Request for Comments) is an Internet formal document or standard that is
	the result of committee drafting and subsequent review by interested parties. Some
	RFCs are informational in nature. Of those that are intended to become Internet
	standards, the final version of the RFC becomes the standard and no further
	comments or changes are permitted. Change can occur, 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.

Router

SAP

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.

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.
Shoulder	Looking over someone's shoulder to see the numbers they dial on a phone, or the
Surfing	information they enter into a computer.
Slave	Any device that is controlled by another device called the master.
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.
SON	(Service Order Number): The SON is the number issued by the local exchange
	carrier to confirm the order for the ISDN service. It provides a matching number for
SPAM	cross-referencing the order to the phone company.
	Unwanted e-mail, usually in the form of advertisements.
SPID	(Service Profile Identifier): The ISDN switch needs to have a unique identification
Spoofing	number for each ISDN set to which it sends calls and signals.
	To forge something, such as an IP address. IP Spoofing is a common way for
	hackers to hide their location and identity.
