In computing terms, a plug-in (or plugin, add-on, 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 (Wikipedia). In other words, plugins allow additional functions to be performed on top of the default functions the particular software or website is designed for.
There are many different kinds of plugins available for downloads. The most common examples are plugins or extensions made for web browsers. These extensions are exclusive for the particular web browser they are made for. For instance, plugins or extensions for Chrome will not be applicable for Internet Explorer and vice versa.
Plugins or extensions for web browsers are able to perform a variety of tasks from enabling the use of emoticons to changing your browsing location (comes in handy where access to some web pages is not authorized when user is browsing from within certain countries). Some of the well-known browser plugins include Adobe Flash Player, QuickTime Player, and Twinword Finder. Adobe Flash Player and QuickTime Player enables the web browser to read files written in certain format (SWF, AVI and etc.) that it would otherwise be unable to, by default. Twinword Finder on the other hand, is an add on semantic search functionality for browsers. It reduces research time by providing related search results through understanding of searcher intent and the contextual meaning of terms. Find-on-page results are returned in highlighted paragraphs on the web page.
Web browser plugins and extensions are available for download in their respective web browser plugin stores:
