Virtual Reality

Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.

Universal Plug and Play (UPnP)

 See also Plug and Play , an earlier, proprietary Microsoft approach.

Universal Plug and Play (UPnP) is a standard that uses Internet and Web protocol s to enable devices such as PCs, peripherals, intelligent appliances, and wireless devices to be plugged into a network and automatically know about each other. With UPnP, when a user plugs a device into the network, the device will configure itself, acquire a TCP/IP address, and use a discovery protocol based on the Internet's Hypertext Transfer Protocol ( HTTP ) to announce its presence on the network to other devices. For instance, if you had a camera and a printer connected to the network and needed to print out a photograph, you could press a button on the camera and have the camera send a "discover" request asking if there were any printers on the network. The printer would identify itself and send its location in the form of a universal resource locator ( URL ).

VRML (Virtual Reality Modeling Language)

VRML (Virtual Reality Modeling Language) is a language for describing three-dimensional ( 3-D ) image sequences and possible user interactions to go with them. Using VRML, you can build a sequence of visual images into Web settings with which a user can interact by viewing, moving, rotating, and otherwise interacting with an apparently 3-D scene. For example, you can view a room and use controls to move the room as you would experience it if you were walking through it in real space.

Core-Dump

A core dump is the printing or the copying to a more permanent medium (such as a hard disk ) the contents of random access memory ( RAM ) at one moment in time. One can think of it as a full-length "snapshot" of RAM. A core dump is taken mainly for the purpose of debugging a program. With the arrival of higher-level languages and interactive debugging, few problems require a core dump these days. It's more likely to be used by specialized programmers who maintain and occasionally have to debug problems in operating system.
