●
LAN (Local Area Network)
A network structured within a relatively small
range such as in a single building or an office of
a company.
●
DHCP (Dynamic Host Control Protocol)
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.
●
WAN (Wide Area Network)
A network structured within a wide area such
as between the main office of a company and
its branch offices. Internet is also generally re-
ferred to as WAN.
●
Sub-Netmask
An IP address has the following two roles: 1)
address for identifying the network, and 2) ad-
dress for identifying individual computers. Sub-
Netmask is a 32-bit value that defines the num-
ber of bits of the IP address to use for identify-
ing the network.
●
Gateway
Hardware and software that translates different
types of protocols when a computer communi-
cates with another computer outside the net-
work. The gateway IP address is referred to as
the gateway address.
●
RTP (Realtime Transport Protocol)
Protocol to transmit in realtime digitalized video/
audio data via a network.
●
RTSP (Real Time Streaming Protocol)
Protocol to control realtime transmission of
video/audio data via a network.
●
HTTP (Hypertext Transport Protocol)
Protocol used when transferring HTML
(Hypertext Markup Language) files between
WWW server and web browser.
●
Protocol

●
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 surround-
ing access points, etc., to avoid doubling.
●
ESS-ID (wireless LAN)
Network identification name used by wireless
LAN. The name is used to distinguish other wire-
less LAN devices.
●
Ad hoc mode (wireless LAN)
A mode for direct communication without pass-
ing through an access point.
●
Infrastrucre (wireless LAN)
Form of communication via an access point.
●
Encryption 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 information leakage.
40bit WEP:
Encryption is performed using 40-bit encryption key.
128bit WEP:
Encryption is performed using 104-bit + 24-bit
(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 (Advanced Streaming Format)
Data streaming format developed by Microsoft
Corporation (U.S.) for transmission of video and
audio.
●
Host name
Name of a device (not limited to a computer but
all connection devices with an IP address) on a
