A Site Collection is a container for storing SharePoint sites. In SharePoint Online, you create a Site Collection using the Office 365 Administration interface. Using SharePoint Online is nearly identical to using SharePoint that has been installed at your local organization. The only difference is that Microsoft manages SharePoint in its own data centers in the Online version and you access the application over the Internet.

From a user’s point of view, it’s just SharePoint. At the highest level of administration, there are differences in how you create a Site Collection.
