What is the difference between "stopped" and "stopped (deallocated)"?

Azure VMs can exist in several states including “stopped” and “stopped (deallocated)”. Shutting down the VM from within the OS puts the VM in a “stopped” state. In that state you still accrue charges for the VM and for any OS and data disks. Putting the VM in a “deallocated” state releases the hold on the backend Azure host resources so once the VM is in that state you are not charged for the VM but you are still charged for the OS and any data disks.
