Domain Controller

A Domain Controller is a specialized server in a computer network that manages access to resources and enforces security policies. It authenticates users when they log in, ensuring they have the right permissions. Think of it as a security gatekeeper that verifies identities and grants or denies access based on established rules. In organizational networks, the Domain Controller helps maintain centralized management of user accounts, passwords, and permissions, making it easier to control who can do what within the network securely and efficiently.
