802.11g

IEEE802.11g uses the 2.4 GHz frequency for greater range. 802.11g supports bandwidth up to
54 Mbps and is backwards compatible with 802.11b.

Access Point

In a wireless local area network (WLAN), an Access Point is a station that transmits and re-
ceives data (sometimes referred to as a transceiver). An Access Point connects users to other
users within the network and also can serve as the point of interconnection between the WLAN
and a fixed wire network. Each Access Point can serve multiple users within a defined network
area; as people move beyond the range of one Access Point, they are automatically handed
over to the next one. A small WLAN may only require a single Access Point; the number re-
quired increases as a function of the number of network users and the physical size of the net-
work.

WEP

Wired Equivalent Privacy is a data encryption protocol for 802.11 wireless networks. All wire-
less nodes and access points on the network are configured with a 64-bit, 128-bit or 152-bit
Shared Key for data encryption.

Access Control This function is only valid under AP mode, invalid under the mode of bridge graft. Used in MAC

address to filter.

Bridge

Bridge is the device that connects and transmits data packets with two subnets by the same
protocol and it works in the LLC layer of OSI.

DHCP or

DHCP stands for "Dynamic Host Configuration Protocol".

DHCP Client or

DHCP purpose is to enable individual computers (DHCP Client) on an IP network to extract

DHCP Server

their configurations from a server (the 'DHCP server') or servers, in particular, servers that have
no exact information about the individual computers until they request the information. The
overall purpose of this is to reduce the work necessary to administer a large IP network. The
most significant piece of information distributed in this manner is the IP address.

Encryption

For the security of transmit data in network, the data should be encrypted before transmit and
decrypt received data.

IP Address

Internet Protocol is the main internetworking protocol used in the Internet. Used in conjunction
with the Transfer Control Protocol (TCP) to form TCP/IP.

LAN&WAN

LAN. A communications network serving users within a limited area, such as one floor of a
building. A LAN typically connects multiple personal computers and shared network devices
such as storage and printers. Although many technologies exist to implement a LAN, Ethernet
is the most common for connecting personal computers. A long distance link used to extend or
connect remotely located local area networks. The Internet is a large WAN.

MAC Address

Short for Media Access Control address, a hardware address that uniquely identifies each node
of a network.

NetBIOS

Network Basic Input Output System. An application programming interface (API) for sharing
services and information on local-area networks (LANs). Provides for communication between
stations of a network where each station is given a name. These names are alphanumeric
names, 16 characters in length.

Ping

A command line program in Windows, use it to check the connection whether is reachable.

Router

A device that forwards data between networks. An IP router forwards data based on IP source
and destination addresses.

Graphical User

In this kind of user interface, user can use Microsoft Internet Explorer or other browser to

Interface (GUI)

control, guard and manage the device.

WINS Server

WINS. Windows Internet Naming Service is a server process for resolving Windows-based
computer names to IP addresses. If a remote network contains a WINS server, your Windows
PCs can gather information from that WINS server about its local hosts. This allows your PCs
to browse that remote network using the Windows Network Neighborhood feature.
