Virtual Private Network - VPN
1. For data, the logical configuration of a group of hardware components that includes direct connection THROUGH (as opposed to TO) the Internet. Usually refers to a network in which some of the parts are connected using the public Internet, but the data sent across the Internet is encrypted, so the entire network is "virtually" private. This sort of arrangement allows certain users reasonable access to a fully operational corporate network via the Internet.
2. In telephony, a switched network with special services like abbreviated dialing. A customer can call between offices in different area codes without having to dial all eleven digits.
Virtual Reality Markup Language - VRLM
A scripting language used to define three-dimensional "worlds". VRML, pronounced ver-mal, and short for Virtual Reality Markup (or Modeling) Language, VRML is a specification for displaying 3-dimensional objects on the World Wide Web. You can think of it as the 3-D equivalent of HTML. Files written in VRML have a.wrl extension (short for world). To view these files, you need a VRML browser or a VRML plug-in to a Web browser. VRML produces a hyperspace (or a world), a 3-dimensional space that appears on your display screen. And you can figuratively move within this space. That is, as you press keys to turn left, right, up or down, or go forwards or backwards, the images on your screen will change to give the impression that you are moving through a real space. The newest VRML 2.0 specification was finalized in August, 1996. It is known officially as ISO/IEC 14772.
