• Java
  Developed by Sun Microsystems, Java is an object-oriented programming language, similar to C++. Java-based applications, or applets, can be quickly downloaded from a Web site and run using a Java-compatible Web browser such as Microsoft Internet Explorer or Netscape Navigator. Java applets are the most widespread use of Java on the Web.

  Java programs or source code files (.java) are compiled into a format known as bytecode files (.class). These files, once complied, can be executed by a Java interpreter. Most operating systems, including Windows, Macintosh OS, and UNIX, have Java interpreters and run-time environments known as Java Virtual Machines.

• Java applet
  A Java applet is an HTML-based program built with Java that a browser temporarily downloads to, and runs from, a user's hard disk. Java applets can be downloaded and run by any Java-interpreting Web browser, such as Microsoft Internet Explorer and Netscape Navigator. Java applets can be used to add multimedia effects, such as background music, real-time video displays, animations, and interactivity, such as calculators and games, to Web pages.
• Java Database Connectivity (JDBC)
  JDBC is a data access interface based on ODBC and used with the Java programming language.
• JavaScript
  JavaScript is a scripting language that interacts with HTML source code and is compatible with the Java programming language. JavaScript is Netscape's implementation of the ECMA-262 standard. (See also: Microsoft JScript)

• Joint Photographic Experts Group (JPEG, JPG)
  JPEG is a widely accepted international standard for the compression of color images often used on the Internet. Although dependent on the capabilities of the user's computer, JPEG or JPG files display up to 16.7 million colors and offer a variety of compression levels. The JPEG file format is best used to display high-quality photographic images, since highly compressed JPEGs (low-quality settings) can appear muddy and are usually of lower quality than GIFs of a similar file size.
