Java:

Java refers to a programming language. The syntax of Java is object-oriented and structured around classes instead of functions. Java can also be used for programming applets or small programs that can be embedded in websites. The language is becoming increasingly popular among both web and software developers since it is efficient and easy to use.

JavaScript:

Like Java, this is a programming language, which can be integrated into standard HTML pages. While JavaScript is based on the Java syntax, it is a scripting language, and therefore cannot be used to create stand-alone programs. Instead, it is used mainly to create dynamic, interactive web pages. For example, web developers can use JavaScript to validate form input, create image rollovers and to open pop-up windows.

JPEG:

The term actually stands for “Joint Photographic Experts Group” because that is the name of the committee that developed the format. A JPEG (file extension .JPG or .JPEG) is a compressed image file format. JPEG images are not limited to a certain amount of color, like GIF images are. Therefore, the JPEG format is best for compressing large, colorful photographic images. While JPEG images can contain colorful, high-resolution image data, it is a lossy format, which means some quality is lost when the image is compressed. If the image is compressed too much, the graphics become noticeably “blocky” and some of the detail is lost. Like GIFs, JPEGs are cross-platform, meaning the same file will look the same on both a Mac and PC.
