Java®
A platform-independent object-oriented programming language designed for the web and developed by Sun Microsystems. A Java® application on the web, an applet, is downloaded by a client and then runs on the client's computer. Since it is platform-independent, a separate Macintosh®, Microsoft® Windows®, etc. version is not needed.
JavaScript®
A programming language that is interpreted by both majors web browsers (though not necessarily in identical ways) and is used to enhance a web page, for instance, by accepting user input. JavaScript® is not related to Java®.
Joint Photographic Experts Group - JPEG
A graphics file format developed by the ISO. JPEG files are more useful when the image contains a large color palette while the GIF format is more suited to a smaller number of colors. The compression algorithm for JPEG is a lossy one so image resolution is lost as the file is compressed; greater compression leads to greater loss.
