- Virtual Reality
-
The term "virtual reality" is more generally used to refer to any virtual world represented in a computer, even
if it's just a text-based or graphical representation. The ideal virtual reality
would entail the use of audio and visual devices attached to the user so that
what he sees and hears are controlled by the computer.
- Visual Basic
- A programming language and environment based on the BASIC language developed by
Microsoft in 1990. Visual Basic was one
of the first products to provide a graphical programming environment and a paint metaphor for developing user interfaces.
Instead of worrying about syntax details, the Visual Basic programmer can add a substantial amount of code simply by
dragging and dropping controls, such as buttons and dialog boxes, and then defining their appearance and behavior.
Visual Basic is sometimes called a Rapid Application Development (RAD) system because it enables programmers to quickly
build prototype applications. It is sometimes called an event-driven language because each object can react to different
events such as a mouse click. Since its launch in 1990, the Visual Basic approach has become the norm for programming
languages. Now there are visual environments for many programming languages, including C, C++, Pascal, and Java.
