What is a web application in SharePoint?

A SharePoint web application is a collection of one or more IIS websites configured to map incoming HTTP requests to a set of SharePoint sites. A SharePoint 2016/2013 web application is composed of an Internet Information Services (IIS) web site that acts as a logical unit for the site collections that you create.

The web application also maps each SharePoint site to one or more specific content databases. SharePoint Foundation uses content databases to store site content such as list items, documents, and customization information.

When you create a web application in SharePoint Foundation, it creates an IIS website with a root folder containing a web.config file at the following location:
C:\inetpub\wwwroot\wss\VirtualDirectories
