What is a plug-in? In computing, a plug-in is a set of software components that add specific ability to a larger software application. WordPress cannot do everything. WordPress can do only a few things. So, the things that WordPress cannot do, people write a plug-in to do it. For example, you can write a plug-in to do the verification for your Webmaster account. This feature is not available under WordPress but you can download a plug-in and once a plug-in gets installed, you can use that software.
A lot of people write plug-ins and you can write your own custom plug-ins. If there is anything that you want a website to do but the feature is not available on your WordPress website, you can write a plug-in for that. You can even download plug-ins that aer available for free and you can even modify a particular downloaded plug-in if it doesn’t do exactly what you want it to do. There there are hundreds of plug-ins available for WordPress that you can download, install and use on your WordPress website.
The major advantage of using a content management system like WordPress is that it is basically an interactive system and using this interactive system you can build a fairly sophisticated website. This is the main reason why people are so much attracted towards WordPress.
