URL (Universal Resource Locator) – URLs are used to describe the location of web pages, and are also
used in many other contexts. An example of an URL is http://www.ssh.com/ipsec/index.html. URLs are defined
in IETF RFCs 1738 and 1808.
Verification – The act of recognizing that a person or entity is who or what it claims to be.
VLAN (Virtual Local Area Network) – A function allowing some Ethernet switches to be divided into smaller
logical groups known as VLANs. On most switches each VLAN operates completely independent of the others,
as if each was a separate physical device. Some higher-end switches can also route between VLANs as if each
was a separate hub/switch connected by a router.
VPN (Virtual Private Network) – A device or program that protects users and their data when exchanging
information over the Internet. A VPN can use encryption, user authentication, and/or firewall protection to solve
remote access security threats.
WAN (Wide Area Network) – A data network, typically extending a LAN beyond a building or campus, linking
to other (remote) LANs.
