To manage Joomla!'s extended functionality, you'll find yourself working with both the Components and the Extensions menu in the backend. The main difference between these two is that components are more powerful and more complex; they're applications within the Joomla! application. Modules are smaller add-ons that can contain all sorts of dynamic information. Sometimes, components and modules are designed to work together.

So, in spite of the differences between components and extensions, behind the scenes, they generally serve the same purpose. Both enhance your site's functionality.
