GLOSSARY
Netmask
Determines what portion of an IP address designates the Network and
which part designates the Host.
Network Interface Card
NIC. A card installed in a computer or built onto the motherboard that
allows the computer to connect to a network.
Network Layer
The third layer of the OSI model which handles the routing of traffic on
a network.
Network Time Protocol
Used to synchronize the time of all the computers in a network.
NIC
Network Interface Card.
NTP
Network Time Protocol.
OFDM
Orthogonal Frequency-Division Multiplexing is the modulation tech-
nique for both 802.11a and 802.11g.
OSI
Open Systems Interconnection is the reference model for how data
should travel between two devices on a network.
OSPF
Open Shortest Path First is a routing protocol that is used more than
RIP in larger scale networks because only changes to the routing table
are sent to all the other routers in the network as opposed to sending
the entire routing table at a regular interval, which is how RIP func-
tions.
Password

resources on a network.
Personal Area Network

each over a serial interface, like a phone line.
PPPoE
Point-to-Point Protocol over Ethernet is used to connect multiple com-
puters to a remote server over Ethernet.
PPTP
Point-to-Point Tunneling Protocol is used for creating VPN tunnels over
the Internet between two networks.
Preamble
