A plug-in is a piece of software code that allows a programme to do something it is not able to do by itself. A good example of a plug-in is the commonly used Adobe Flash Player. Without Flash Player you wouldn’t, for example, be able to view BBC News bulletins that are embedded into web pages.

There are many different types of plug-ins, accomplishing many different things. There are plug-ins for optimising your Google rankings, such as the ‘All-in-one-SEO’ plug-in, plug-ins for social media networking, plug-ins to prevent unwanted comments on your websites, and many more.

In fact, an abundance of plug-ins exist. Email programmes will use privacy plug-ins for security. Media players might need a plug-in to play a specific type of media. And so on. (Have a look in the Useful Resources at the back of the book for a comprehensive listing of plug-ins.)
