●
IP ad
dress
Identification number assigned to each computer that is connected to a network.
The address is used for communication between
network devices.
●
LAN (Local Area Netw
ork)
A
network structured within a relatively small range such as in a single building or an of
fice of a company
.
●
DHCP (Dynamic Host Contr
ol Pr
otocol)
Method of automatically assigning IP
address within a network. When a computer is connected to a network, the DHCP
server
automatically assigns the IP
address.
●
W
AN (Wide Area Netw
ork)
A
network structured within a wide area such as between the main of
fice of a company and its branch of
fices. Internet is also
generally referred to as W
AN.
●
Netmask An IP
address has the following two roles: 1) address for identifying the network, and 2) address for identifying individual co
mputers.
Netmask is a 32-bit value that defines the number of bits of the IP
address to use for identifying the network.
●
Gate

y
Hardware and software that translates dif
ferent types of protocols when a computer communicates with another computer outside t
he
network.
The gateway IP
address is referred to as the gateway address.

●
Pr
otocol
A
set rule for a computer or communication device to perform communication over a network, etc.
●
IEEE802,11b International standard for wireless LAN with maximum communication speed of 1
1Mbps.
●
Channel (wireless LAN) Frequency range used by wireless LAN.
The same frequency must be set by two sides for proper communication.
If there is an access point, adapter
, etc., using the same band in the proximity
, there may be a hindrance in the communication
and
may reduce throughput or the quality of communication. When setting, check the settings of surrounding access points, etc., to
avoid
doubling.
●
ESS-ID (wireless LAN) Network identification name used by wireless LAN.
The name is used to distinguish other wireless LAN devices.
●
Ad hoc mode (wireless LAN) A
mode for direct communication without passing through an access point.
●
Infrastrucre (wireless LAN) Form of communication via an access point.

Encr
yption mode
Setting for encrypting the flow of data during wireless communication. Following settings are available: None
(Open
System):
No encryption. Setting will be unavailable and throughput will be improved. However
, there is the risk of in
for-
mation leakage.
40blt
WEP:
Encryption is performed using 40-blt encryption key
.
128blt:
Encryption is performed using 104-blt + 24-blt (1V) keys.
Although throughput will decline compared to Open
System, security of data will be improved.
●
Access point (wireless LAN) Relay point for infrastructure communication. It can also serve as the relay point for cable LAN or wireless LAN.
●
ASF (Ad

TCP/IP Abbreviation for
T
ransmission Control Protocol/Internet Protocol and is one of the protocols used during network connection.
●
UDP Dif
ferent from
TCP
, UDP
is a low-level protocol that does not perform receive checks. In some cases, missing and distorted imag
