User's Manual

Plug-and-Play - The ability of a computer system to configure expansion
boards and other devices automatically without requiring the user to turn off
the system during installation.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal com-
puter are external sockets for plugging in communications lines, modems and
printers.
PPPoE (Point to Point Protocol over Ethernet) - PPPoE is a method for the
encapsulation of PPP packets over Ethernet frames from the user to the ISP
over the Internet. One reason PPPoE is preferred by ISPs is because it provides
authentication (username and password) in addition to data transport. A PPPoE
session can be initiated by either a client application residing on a PC, or by
client firmware residing on a modem or router.
PPTP (Point-to-Point Tunneling Protocol) - A protocol (set of communication
rules) that allows corporations to extend their own corporate network through
private "tunnels" over the public Internet. Effectively, a corporation uses a
wide-area network as a single large local area network. A company no longer
needs to lease its own lines for wide-area communication but can securely use
the public networks. This kind of interconnection is known as a virtual private
network.
RIP (Routing Information Protocol) - A simple routing protocol that is part of
the TCP/IP protocol suite. It determines a route based on the smallest hop count
between source and destination. RIP is a distance vector protocol that routine-
ly broadcasts routing information to its neighboring routers.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Roaming - In an infrastructure mode wireless network, this refers to the abili-
ty to move out of one access point's range and into another and transparently
reassociate and reauthenticate to the new access point. This reassociation and
reauthentication should occur without user intervention and ideally without
interruption to network connectivity. A typical scenario would be a location
with multiple access points, where users can physically relocate from one area
to another and easily maintain connectivity.
