Sites versus Site Collection in SharePoint
SharePoint sites and site collection refer to SharePoint sites only. However, there is a slight difference between the two. In this tutorial, we will bring out the difference.
Also known as team collaboration sites, Sites refer to the websites that are created using SharePoint templates. Each template in SharePoint includes a unique set of Lists, Libraries and Pages. Depending on the requirements, you can select the SharePoint template by choosing from the available options.
You can also “Create a SharePoint 2013 Team Site” to organize information about your team members.
Site Collection :
It includes a group of same/different sites forming a hierarchy. The SharePoint site on the top most point of this hierarchy is also sometimes referred as the parent site.
Other SharePoint sites below that main site are called subsites. There can be more than one level of subsites in a particular hierarchy. Following is an example of site collection in SharePoint.
In this, Portal home is the parent site while Sales Portal, Marketing Portal and Finance Portal are the subsites listed under it. Another level of subsites includes the subsites Team Site and Team Blog listed under Sales Portal and Marketing Portal.
You can easily “Create a Site Collection in SharePoint” and can “Delete a Site Collection” as required.
Hopefully this tutorial fully explains the concept of Sites and Sites collection in SharePoint and the difference existing between the two.
