Google offers many applications, including "built-in apps" which come with your Google Account like; Drive, Docs, Presentation, YouTube, Blogger, etc... and "chrome apps & extensions" which you can install (or your GAE admin installs) from the Chrome Web Store. In addition, you have the new Add-ons in your Docs, Forms and Sheets, as well as the ability to access apps, books, videos and music from the Google Play for Education store.
