Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.

More about this video -
In this next video tutorial in our networking and infra concepts series we will learn about Active Directory.

Windows Active Directory aka windows AD is a hierarchal database where you organize, store, administer and secure your enterprise information for entities like employees, servers, printers, file directories, etc.

It is via the active directory that it's decided what all resources within your domain would be able to access each other. This starts right from when you try to login into your laptop and office network. AD authentication checks whether you are a legitimate user or not.

We will start with a real-life example to understand how an active directory works and then explore its logical and physical architecture.

There are 5 key components that make active directory logical architecture -
1. Objects
2. Domains
3. OUs
4. Tree
5. Forest

We will learn about all these components and how it's related to each other. We will also touch base on Windows AD physical architecture and how it works -

a. Domain Controller
b. Data Store
c. Schema
d. Database

By the end of this video, you will have a fair understanding of what is an active directory and how it works!

For a deep dive into advanced Active Directory concepts like installation of AD on Windows 2016 server etc, please refer to the documentation below -
