Under the Software Assurance program, customers acquire the right to install any new release of products covered in the agreement during the term of their coverage
A SharePoint Server client access license (CAL) gives a user the right to access the services of SharePoint Server. This user CAL authorizes a user to access SharePoint Server from any device (for example, when an employee accesses the server from a computer at work and another at home). Device CALs are also available. A device CAL authorizes one computer to access SharePoint Server, regardless of the number of users (for example, a shared workstation).
