Glossary
URL
A Uniform Resource Locator (URL) is a standard for specifying the location of objects on the
Internet, such as a file or a newsgroup. URLs are used extensively in HTML documents to
specify the target of a hyperlink which is often another HTML document (possibly stored on
another computer). The first part of the URL indicates what protocol to use and the second
part specifies the IP address or the domain name where that resource is located.
For example, ftp://ftp.d-link.com/downloads/myfile.tar.gz specifies a
file that should be fetched using the FTP protocol; http://www.dlink.com/index.html
specifies a Web page that should be fetched using the HTTP protocol.
VLAN
A virtual LAN (VLAN) is a software-based, logical grouping of devices on a network that allow
them to act as if they are connected to a single physical network, even though they may not be.
The nodes in a VLAN share resources and bandwidth, and are isolated on that network. The
D-Link DWL-2210AP supports the configuration of a wireless VLAN. This technology is
leveraged on the access point for the “virtual” guest network feature.
VPN
A Virtual Private Network (VPN) is a network that uses the Internet to connect its nodes. It
uses encryption and other mechanisms to ensure that only authorized users can access its
nodes and that data cannot be intercepted.
WAN
A Wide Area Network (WAN) is a communications network that spans a relatively large
geographical area, extending over distances greater than one kilometer. A WAN is often
connected through public networks, such as the telephone system. It can also be connected
through leased lines or satellites. The Internet is essentially a very large WAN.
WDS
A Wireless Distribution System (WDS) allows the creation of a completely wireless
infrastructure. Typically, an Access Point is connected to a wired LAN. WDS allows access
points to be connected wirelessly. The access points can function as wireless repeaters or
bridges.
WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks.
All wireless stations and access points on the network are configured with a static 64-bit (40-
bit secret key + 24-bit initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV) Shared
Key for data encryption. It uses a RC4 stream cipher to encrypt the frame body and CRC of
each 802.11 frame before transmission.
Wi-Fi
A test and certification of interoperability for WLAN products based on the IEEE 802.11 standard
promoted by the Wi-Fi Alliance, a nonprofit trade organization.
