What is SharePoint?
SharePoint is a powerful collaboration platform that lets you share and manage content, knowledge and applications to enhance teamwork.
SharePoint Server can be used on-premises or with a Microsoft 365 Enterprise subscription to take advantage of all the latest features. Share common resources and applications across sites. Use search to locate information and expertise in your organization. And stay informed with personalized news in SharePoint Home and SharePoint mobile apps.
If you are new to SharePoint Server, make a plan about what you want to do and where you plan to go next. If SharePoint has never been deployed, consider how extensive an installation is needed. Do you have a large enterprise environment with hundreds or more licenses? If you have a smaller distribution in mind Hardware requirements and budget may also be a factor of your distribution.
Depending on your version, system requirements and prerequisites may vary.
