Plug-in

• Small programs written in Java, which are downloaded as needed and executed within a Web page or browser.
• A program installed in the browser to extend its basic functionality. Allows different file formats to be viewed as part of a standard HTML document.
• An element on a Web page that contains data and procedures for how that item will react when activated. On a Web page, an object is typically a multimedia presentation.
• Programming concept based on objects and data and how they relate to one another, instead of logic and actions; C++ and Java are OOP languages.

Portable Document Format (PDF)

• A free, open-source alternative to the MP3 compression format for audio files; creates smaller, faster downloading files.
• A file format that can be transferred across platforms and retain its formatting; designated by the file name extension .pdf.
• A type of data file compression in which all original data can be recovered when the file is decompressed.
• Style sheet language that provides the formatting and "look" of a Web page or document written in a markup language.

Viewer

• Storage space on a computer hard disk used to temporarily store downloaded data.
• A compression/decompression algorithm used by modern video and audio player plug-ins.
• Small programs written in Java, which are downloaded as needed and executed within a Web page or browser.
• A scaled-down version of an application; designed to view and print files.

Joint Photographic Expert Group (JPEG)

• A plug-in developed by Apple Computer for storing movie and audio files in digital format.
• A graphical image file format commonly used for photographs.
• Portable text file format created by Microsoft that allows image insertion and text formatting; an almost universal format.
• A graphical image file format commonly used in HTML documents.

Musical Instrument Digital Interface (MIDI)

• A standard computer interface for creating and playing electronic music. It allows computer to re-create music in digital format for playback.
• A file format that can be transferred across platforms and retain its formatting; designated by the file name extension .pdf.
• Style sheet language that provides the formatting and "look" of a Web page or document written in a markup language.

Streaming media

• Style sheet language that provides the formatting and "look" of a Web page or document written in a markup language.
• A free, open-source alternative to the MP3 compression format for audio files; creates smaller, faster downloading files.
• Resizable images that are saved as a sequence of vector statements, which describes a series of points to be connected.
• A continuous flow of data, usually audio or video files, that assists with the uninterrupted delivery of those files into a browser.

 Object-oriented programming (OOP)

• A program installed in the browser to extend its basic functionality. Allows different file formats to be viewed as part of a standard HTML document.
• A graphical image file format commonly used in HTML documents.
• A standard computer interface for creating and playing electronic music. It allows computer to re-create music in digital format for playback.
• Programming concept based on objects and data and how they relate to one another, instead of logic and actions; C++ and Java are OOP languages.

 Applets

•  Small programs written in Java, which are downloaded as needed and executed within a Web page or browser.
•  A type of data file compression in which all original data can be recovered when the file is decompressed.
•  An open set of technologies for integrating components on the Internet and within Microsoft applications.
•  A program installed in the browser to extend its basic functionality. Allows different file formats to be viewed as part of a standard HTML document.
