a. Designed to be plugged into an electrical power outlet or circuit. alt. Designed to be plugged into an electrical power outlet or circuit. n. (context computing English) A computer program module or device that interacts with another to add a specific function, or to support a specific file format or device.
In computing, a plug-in (or plugin, add-in, addin, add-on, addon, or extension) is a software component that adds a specific feature to an existing computer program. When a program supports plug-ins, it enables customization. The common examples are the plug-ins used in web browsers to add new features such as search-engines, virus scanners, or the ability to use a new file type such as a new video format. Well-known browser plug-ins include the Adobe Flash Player, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution on a local Java virtual machine.
A theme or skin is a preset package containing additional or changed graphical appearance details, achieved by the use of a graphical user interface (GUI) that can be applied to specific software and websites to suit the purpose, topic, or tastes of different users to customize the look and feel of a piece of computer software or an operating system front-end GUI (and window managers).
Plug-in is the term used for the add-on files used to modify the Escape Velocity series of games by Ambrosia Software. They are similar to what is now often referred to as a " mod" for other games, but that term was not common when Escape Velocity was first created, and in any case the Macintosh development community generally prefers clearer and more accessible terminology. Another difference in the terminology is that while ‘mods” often involve a certain amount of reverse-engineering of the game engine (since developers prefer to sell their own expansion packs), plug-ins are specifically authorised and facilitated by the developers.
Plug-ins are collected on the official web sites for the Escape Velocity games (or, of course, can be downloaded from a plug-in creator’s own site) and are installed by placing them in the ‘Plug-ins’ folder within the game folder. The effects of the plug-in will be active so long as the game is run with the file in the correct folder.
