Java - Java is an object-oriented programming language developed by Sun Microsystems. The language was intended to replace C++, although the feature set better resembles that of Objective C. It can be used to build small application modules or applets for use as part of a Web page. Applets make it possible for a Web page user to interact with the page. Java should not be confused with JavaScript, which shares only the name and a similar C-like syntax. Official Site
JavaScript - JavaScript is a platform independent, client-side scripting Language which means that it is interpreted by the client's browser and not compiled on the web server. JavaScript allows webmasters to add interactive features to their sites. JavaScript was developed by Netscape and originally called LiveScript. JavaScript Study Guide
JPEG (Joint Photographic Experts Group) - A JPEG is a 24 bit bitmap image format that can be a very efficient way to compress graphics for web sites due to its use of lossy compression. You can select how much to compress a file, and therefore how much information is lost. The JPEG format does not support animation or transparency. JPEG images use the .jpg file extension.
JScript - JScript is Microsoft's implementation of JavaScript. JScript was first supported in Internet Explorer browser 3.0 released in August, 1996.
JSP (JavaServer Pages) - JSP pages provide a simplified, fast way to create web pages that display dynamically-generated content. You can use JSP tags or scriptlets to generate the dynamic content. The logic that generates the content is encapsulated in tags and JavaBeans components and tied together in scriptlets, all of which are executed on the server side. On the server, a JSP engine interprets JSP tags and scriptlets, generates content (for example, by accessing JavaBeans components, accessing a database with JDBC technology, or including files), and sends the results back in the form of an HTML (or XML) page to the browser. The function of JSP is similar to ASP, however, JSP is an open standard.
 Jumpers - A metal bridge that closes an electrical circuit. Typically, a jumper consists of a plastic plug with metal contacts inside that fits over a pair of protruding pins. Jumpers are sometimes used to configure expansion boards, hard drives, and other devices. By placing a jumper plug over a different set of pins, you can change a board's parameters.
