7-8 Glossary

Access point

A generic name for devices or points to connect a wired LAN and wireless LAN.

BSS ID (Basic Service Set-IDentifier)

Specified wireless LAN in MAC class.

The ID is uses the MAC address that is assigned to each network device.

Client

A generic name for network devices which relay packets at a MAC address level.

Crossover Cable

The transmission signal cable and receiving signal cable are cross wired to communicate correctly. Generally, used for connection between the PCs.

DHCP server

DHCP (Dynamic Host Configuration Protocol) is a protocol for a client to obtain necessary information automatically from a server on the TCP/IP network. The DHCP server controls IP address, default gate- way, domain name, etc. as network information. AP- 12, which has the DHCP server function, obtains the IP address, default gateway, DNS address, etc. when the DHCP client (Computer) has started.

ESS ID (Extended Service Set-IDentifier)

A name for identification to create several network groups in a communication area in a wireless LAN. In the wireless network group which communicates to AP-12, the identifier of the wireless terminal must be the same as that of AP-12.

Ethernet

A LAN communication system developed by Xerox, DEC and Intel. 10BASE-T, 100BASE-TX, 10BASE- 5, 10BASE-2, etc. are available depending on the cable type.

Global IP address

A unique address assigned to a device. One global IP address is assigned to only one device in the world.

HUB

A hub is required when the AP-12 and other devices are used to construct a network. 10BASE-T or 100 BASE-TX cable is used for the connection to the hub.

IP (Internet Protocol) address

32-Bit address to identify all the devices connected to a network in which the TCP/IP protocol is used. Usually, the IP address consists of four 8-bit numer- ical character strings of decimal notation (e.g., 192.168.0.1). A private IP address specified by a network administrator does not need to apply to an address administration agency or internet service provider. However, the network administrator must assign the private address according to the rules below. The private address must be converted into a global IP address when connecting to an external network. The IP addresses below can be used as the private IP address.

Class A: 10.0.0.0 to 10.255.255.255

Class B: 172.16.0.0 to 172.31.255.255

Class C: 192.168.0.0 to 192.168.255.255

LAN (Local Area Network)

A relatively small-sized network in the same floor or the same site.

MAC address (Media Access Control Address)

A physical address specified in individual wired or wireless products. The network device manufactur- ers control this address so that a unique number can be assigned to only one product in the world. Ethernet equipment and wireless LAN products send and receive a frame according to this MAC address.

Network

The state that some devices such as a server, work- station, Computer, etc. are connected to a commu- nication system through a cable or ADSL line, to transmit data.

Packet

A unit to send/receive data. The packet consists of a header, which contains information necessary for sending/receiving, and data section which is the data itself.
