Java is a modern
Programming Language, first seen in 1995, & is used to bring
Web Pages to life. Java programs are referred to as
applets. Java is an interpreted, object-orientated program language with a
syntax and structure similar to C++, designed specifically for the
internet by Sun Microsystems. One huge plus for Java is that Java programs can run on many different types of computer (e.g. IBM PC, Apple Macintosh). Java Applets are always small in size & can be downloaded from the Internet & executed as part of the Web page being displayed. Once a programmer has completed the Java program it is compiled to produce an executable module. This executable module has instructions written for the "Java virtual machine" - this is designed for the
platform on which the module is to be executed. These instructions are interpreted on the platform where the program is being executed. The "Java Virtual Machines" are available for a number of operating environments e.g.
Windows, AIX, OS/2.
JavaScript is a
Programming Language for developing Client
Internet applications. The
WEB Browser interprets JavaScript statements embedded in an
HTML page. It is only very vaguely related to Java. JavaScript is intimately tied to the
World-Wide Web, and currently runs in only three environments - as a server-side scripting language, as an embedded language in server-parsed HTML, and as an embedded language run in browsers.
A color
image graphics compression format in which a lossy compression method is used and some
data is sacrificed to achieve greater compression. The compression format looks for large bodies of color in a picture and throws away big chuncks of this redundant infomation to compress 3/4 of the data and make it transfer faster on the
net.
