Site Collection

A SharePoint site collection is a group of sites that share a common top-level site, and share features, navigation, and permissions. Site collections are used to organize and manage related sites within a SharePoint environment. They are typically created and managed by SharePoint administrators and can be used to provide a consistent look and feel across related sites, and to enforce common policies and procedures.

Each site collection has its own unique URL and contains one or more subsites, which can be used to organize and manage related content. SharePoint site collections can also be used to manage permissions so that different users and groups can have different levels of access to the sites and content within the collection. This allows for fine-grained control over who can view, edit, and manage content within the collection.
