Microsoft Technet: –  KMS Overview – (Key Management Service)
Let’s start with a quick refresher on KMS activation. KMS is a client – server model. It is conceptually similar to DHCP. Instead of handing out IP addresses to clients on their request, KMS enables product activation. KMS is also a renewal model, with the clients attempting to reactivate on a regular interval. There are two roles: the KMS host and the KMS client.
