Network Time Protocol
O
OFDM
Orthogonal Frequency-Division Multiplexing is the modulation technique 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 APs in the network as opposed
to sending the entire routing table at a regular interval, which is how RIP functions
P
Password
A sequence of characters that is used to authenticate requests to resources on a network
Personal Area Network
The interconnection of networking devices within a range of 10 meters
Physical layer
The first layer of the OSI model. Provides the hardware means of transmitting electrical signals on
a data carrier
Ping
A utility program that verifies that a given Internet address exists and can receive messages. The
utility sends a control packet to the given address and waits for a response.
PoE
Power over Ethernet is the means of transmitting electricity over the unused pairs in a category 5
Ethernet cable
Port
A logical channel endpoint in a network. A computer might have only one physical channel (its
Ethernet channel) but can have multiple ports (logical channels) each identified by a number.
PPP
Point-to-Point Protocol is used for two computers to communicate with each over a serial
interface, like a phone line
PPPoE
Point-to-Point Protocol over Ethernet is used to connect multiple computers to a remote server
over Ethernet
