Glossary G-3
LPD/LPR A printer protocol that uses TCP/IP to establish connections
between printers on a network. Also known as Line Printer
Daemon/Line Printer Remote.
MAC Address or
Media Access
Control
A hardware address (6-byte) that uniquely identifies each node
of a network. The MAC address is set during manufacturing
and does not change. Also, two Network Interface Cards (NIC)
will not have the same value.
MSCHAPv2
(Challenge
Handshake
Authentication
Protocol)
MSCHAPv2 is the Microsoft® version of CHAP. It is a three-
way handshake protocol that is more secure than PAP. It
provides mutual authentication between devices.
NIC or
Network
Interface Card
An adapter (board or card) that can be inserted into a device,
so the device can be connected to a network. The NIC
converts data from the device into the form transmitted or
received from the network
Node A processing location on a network. The location can be a
workstation, computer, or printer. Each Node has a unique
MAC address.
Open
Authentication
This allows any device to authenticate and then attempt to
communicate with the access point. Any wireless device can
authenticate with the access point, but if WEP is used, the
device can communicate only if its WEP keys match the access
point's. There is no challenge that occurs, you either have the
correct key or not when you communicate with the access
point. By eliminating the challenge process, it actually makes
this more secure than shared key authentication.
PAP (Password
Authentication
Protocol)
A simple authentication protocol used with PPP (Point-to-Point
Protocol). It is a plain text password system, which is not very
secure.
Pathname The location of a particular file or directory that includes the
full path to the needed filename or directory. This is a
combination of path and filename.
PEAP (Protected
Extensible
Authentication
Protocol)
Authenticates clients into a network using only server-side
certificates, which makes implementing and administering a
wireless LAN easier.
Ping A way to determine if a device is accessible. It sends a packet
to the specified address and waits for a reply.
Protocol This is the way two devices transmit data between each other,
including error checking, data compression, and how messages
start and end.
