What is Global Check In?
Click on Tools menu at backend and you will see global check in sub menu. Click on this menu. The Global Check In screen will cause Joomla! to perform a global check-in of all currently pending or locked items. It then shows the results of the Global Check-in. This is useful, for example, if an Article is locked by a User who opened it for editing and never finished the editing session. In this case, other Users are not able to edit this Article. Performing a Global Check-in releases all such items as shown below in figure.

Extensions are add-ons that expand the functionality of Joomla. Extensions are used to add capabilities to Joomla that do not exist in the standard package. Hundreds of Extensions are available for Joomla, with more being developed all of the time.
Extensions are categorized into five types, as follows:
• A Component is a mini-application that renders the main body of the page. Examples of Components are Contacts, the Front Page, and News Feeds.
• A Module is a smaller Extension typically used for rendering a small element that displays across multiple pages. Examples of Modules include Menus and Related Items.
• A Plugin is a section of code that runs when a pre-defined event happens within Joomla. For example, editors are Plugins that run when an edit session is opened.
