mIRC
– mIRC runs under Windows and provides a graphical interface for logging
onto IRC servers and listing, joining and leaving channels.
Network Mask
– also known as the “Subnet Mask”.
OFDM
– Developed for wireless applications, Orthogonal Frequency Division
Multiplexing (OFDM) technology offers superior performance-increased data rates
and more reliable transmissions- than previous technologies, such as DSSS. OFDM is
a scheme in which numerous signals of different frequencies are combined to form a
single signal for transmission on the medium. OFDM works by breaking one
high-speed data stream into a number of lower-speed data streams, which are than
transmitted in parallel. Each lower speed stream is used to modulate a sub-carrier.
Essentially, this creates a multi-carrier transmission by dividing a wide frequency
band or channel into a number of narrower frequency bands or sub-channels. OFDM
is also used for other applications, including powerline networking.
Roaming
- In an infrastructure mode wireless network, this refers to the ability 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.
SSID
(

make connections. In order for wireless devices to communicate, they must all be set
to the same channel and they all must use the same SSID. For instance, if you are
using an access point to connect two computers using wireless devices, the access
point and each of the wireless devices must use the same SSID. Even if they are set to
the same channel, they cannot communicate unless the SSID is the same.
Static IP Address
- A permanent IP address that is assigned to a node in a TCP/IP
network.
Subnet Mask
- The method used for splitting IP networks into a series of subgroups,
or subnets. The mask is a binary pattern that is matched up with the IP address to turn
part of the host ID address field into a field for subnets.
