What Hypertext is
A system for writing and displaying text that can be linked in multiple ways to related documents and available at several levels of detail. The term was coined by Ted Nelson to refer to a nonlinear system of information browsing and retrieval based on associative links between documents. The World Wide Web uses hypertext transfer protocol (HTTP) to link pages and multimedia files.
The meaning of Java
Developed by Sun Microsystems, it is a programming language specifically designed for writing programs that can be safely downloaded through the Internet without fear of viruses or other harm to computers or files. Using small Java programs called applets, Web pages can include functions such as animations, calculators, and other fancy tricks. Java is a simple, robust, object-oriented, platform-independent, multi-threaded, dynamic, general-purpose programming environment. It is best used for creating applets and applications for intranets, the Internet, and any other complex, distributed network.
