Java

Java is a network-friendly programming language invented by Sun Microsystems.
Java is often used to build large, complex systems that involve several different computers interacting across networks, for example transaction processing systems.
Java is also used to create software with graphical user interfaces such as editors, audio players, web browsers, etc.
Java is also popular for creating programs that run in small electronic devices, such as mobile telephones.
Using small Java programs (called "Applets"), Web pages can include functions such as animations, calculators, and other fancy tricks.

JavaScript

JavaScript is a programming language that is mostly used in web pages, usually to add features that make the web page more interactive. When JavaScript is included in an HTML file it relies upon the browser to interpret the JavaScript. When JavaScript is combined with Cascading Style Sheets(CSS), and later versions of HTML (4.0 and later) the result is often called DHTML.

JDK -- (Java Development Kit)

A software development package from Sun Microsystems that implements the basic set of tools needed to write, test and debugJava applications and applets.

JPEG -- (Joint Photographic Experts Group)
