Short-cuts of Active Directory.

1. C.D - Central directory.

Structure of Active Directory.

there are the two types of structure of Active directory.

1. Logical Structure

2. Physical Structure.

Logical Structure.

*Domain
*Tree
*Parent/Root
*Child/ Branch
Forest

Physical Structure.

*Domain Controllers.
*Sites.

Domain:

*  Domain is a logical secure administrative boundary.
*  Creating the initial domain controller in a network also creates the domain- we cannot have a contain without at least one domain controller.
*  Each domain is identified by DNS domain name.

IP Addressing

Internet Protocol Address:

5 classes of IP adress in IPv4

A                                  0-127                                  0                           N.H.H.H

B                                 128-191                              10                          N.N.H.H

C                                 192-223                             110                        N.N.N.H

D                                 224-239                            1110                (Reserved for multicast groups)

E                                 240-255                            1111  (Reserved for research and development purpose)

IP Addressing

*Class A ranges

IP Adress divided into network portion.

Class A written as N.H.H.H

Class B written as N.N.H.H
