Which type of site collection must be used for each web application.

Explanation/Reference:
Note:
* Host-named site collection
Host-named site collections are the preferred method to deploy sites in SharePoint 2013. Because the Office 365 environment uses host-named site collections, new features are optimized for these site collections and they are expected to be more reliable.
* Path-named site collection
Use path-named collections when you need to use alternate access mappings (AAMs).
