To secure access to a company’s resources, such as file shares, permissions can be granted to Active Directory accounts and groups. A Domain Controller (DC) is the server that contains a copy of the AD database and is responsible for the replication of said data between all other DCs within the Domain. You are given a user account (often referred to as your “network login”) to access what has been made available to you.
