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
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
wirelessly. The access points can function as wireless repeaters or bridges.
WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for
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)
for data encryption. It uses a
802.11 frame before transmission.
Wi-Fi
A test and certification of interoperability for
promoted by the Wi-Fi
is connected to a wired LAN.WDS allows access points to be connected
RC4 stream cipher to encrypt the frame body and CRC of each
