A stand-alone wireless hub that allows any computer that has a wireless network
adapter to communicate with another computer and to connect to the Internet.
A communication configuration in which every computer has the same capabilities
and any computer can initiate a communication session. Also known as a peer-to-
peer network or a computer-to-computer network.
One of the networks listed in the Available networks list under Wireless Network
Connection Properties . Any wireless network that is broadcasting and is within
receiving range of the Integrated 54g
bit error rate. The ratio of errors to the total number of bits being sent in a data
transmission from one location to another.
The computer that gets its Internet connection by sharing either the host computer's
connection or the access point's connection.
Unit of expression of power level in decibels with reference to a power of 1 milliwatt.
differential-binary-phase-shift keying.
differential-quadrature-phase-shift keying. A compression technique that transmits
only the differences between the values of the phase of the sine wave rather than
the full absolute value.
direct sequence spread spectrum. A type of radio transmission technology used in
wireless networking and cellular communications.
A mechanism for allocating IP addresses dynamically so that addresses can be
reused when hosts no longer need them.
A capability that allows a number of people to view, modify, and print the same file(s)
from different computers.
gigahertz. A unit of frequency equal to 1 000 000 000 cycles per second.
The computer that is directly connected to the Internet via a modem or network
adapter.
Institute of Electrical and Electronics Engineering
The IEEE draft standard for wireless LAN operations in the 2.4 GHz frequency band
with a maximum data rate of 54 Mbit/s. This draft standard is expected to be finalized
in the summer of 2003.
The IEEE standard for wireless LAN operations in the 2.4 GHz frequency band with
a maximum data rate of 11 Mbit/s.
The address of a computer that is attached to a network. Part of the address
designates which network the computer is on, and the other part represents the host
identification.
local area network
meter
megabits per second. Transmission speed of 1 000 000 bits per second.
megahertz. A unit of frequency equal to 1 000 000 cycles per second.
nanosecond. 1 billionth (1/1 000 000 000) of a second.
orthogonal frequency division multiplexing. An emerging signal modulation
technology for achieving higher data rates in wireless communications.
See ad hoc network . Also known as a computer-to-computer network.
One of the networks that has been configured. Such networks appear under
Preferred networks on the Wireless Networks tab of Wireless Network
Connection Properties .
A value that controls access to a wireless network. The SSID for your wireless
network card must match the SSID for any access point that you want to connect
with. If the value does not match, you are not granted access to the network. You
can have up to three SSIDs. Each SSID can be up to 32 characters long and is case-
sensitive.
A form of data encryption. The WEP key information in the client computer must
match the WEP key used by the access point or host computer. The WEP key can
be enabled or disabled. The WEP key is case-sensitive.
™ enabled notebook appears on the list.
