Windows Server CALs

CAL (Client Access License) licenses for Windows Server are essential elements that enable users and devices to access services offered by Windows Server. There are two main types of CAL licenses: User CAL and Device CAL, which allow for flexible adaptation of the licensing model to the specific needs of an organization. A User CAL is assigned to a specific user and allows access to servers from any device, while a Device CAL is assigned to a specific device and allows server access for any user of that device. The choice of the appropriate type of CAL license depends on the individual requirements and usage of servers within a given organization. CAL licenses are required for the legal use of Windows Server services, such as Active Directory, file servers, and printing, and their purchase is a key element in planning IT infrastructure deployment.
