N
NETBIOS It provides services related to the session layer of the OSI model allowing
applications on separate computers to communicate over a local area
network.
Network Address Translation Network Address Translation is a method by which IP addresses are
mapped from one address realm to another, providing transparent
routing to end hosts.

O
Orthogonal Frequency Division
Multiplexing (OFDM)
OFDM is a frequency-division multiplexing (FDM) scheme, a method of
encoding digital data on multiple carrier frequencies. A large number of
closely spaced orthogonal sub-carrier signals are used to carry data. The
data is divided into several parallel data streams or channels, one for each
sub-carrier, maintaining total data rates similar to conventional
single-carrier modulation schemes in the same bandwidth.
P
Pass Phrase A text string used for WPA security on a wireless network. A passphrase
may contain up to 8 to 64 alphanumeric characters, including spaces and
other special characters.
Ping Ping is a basic Internet program that lets you verify if a particular computer
or device with a certain IP address is reachable. If the computer or device
receives the ping packet, it responds to it, which gives the ping program
the opportunity to display the round-trip time.
Port Number TCP and UDP provide an address mechanism, the port number, for
identifying different applications communicating from the same IP
address. Thus an active Web browser and an independently active mail
program operating from the same IP location would typically use different
port numbers so that packets are correctly delivered to specific
applications.
Probe Request A wireless client sends a probe request frame when it needs to obtain
information from another wireless client or an access point. For example,
a radio NIC would send a probe request to determine which access points
are within range.
Probe Response A wireless client or an access point will respond to the probe request with
a probe response frame, containing capability information, supported
data rates, etc.
