Pages are at the core of the CMS. Each page is a representation of collected content, as every item on a page (text, images, digital media) is stored as content in the CMS repository. This allows content to be reused (permissions permitting) on other pages in other sections of the CMS.
The CMS Authoring Environment is where you manage your webpage content. The authoring environment provides you with a easy to use web-based interface to edit webpages and upload digital assets to the built-in Digital Asset Management (DAM) system.
