TOPOLOGY

Arrangement of device

-          Topology means arrangement of computers and device. We are having two types of topologies. They are

·         Physical Topology

·         Logical Topology

Physical Topology

-           Physical Topology means physical arrangement of computers or devices.

-          Physical Topology are

·         BUS

·         RING

·         STAR

·         TREE

·         MESH

Logical Topology

-          Logical topology means logical arrangements of computers and devices.

-          We are having two types of model in topopogicalies

They are: -

·         Workgroup Model or Peer – to Peer Model

·         Domain Model or Client/Server Model.

Workgroup Model

-          Workgroup Model also called as peer to peer model.

-          Workgroup model computers are individual computer are standalone computer.

-          Workgroup model computer does not depend on any other computers.

-          Workgroup model computer we can create local user accounts.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

-          Workgroup model are local user accounts. We are using  SAM Database(Security Account Manager)




PRACTICAL NO. 1

How to identify workgroup model of computer ?

Domain Model

What is Active Directory?

-          Active Directory is a directory services which contains information of all user accounts and shared resources on a network.

-          Active Directory is a centralized hierarchical directory database.

Purpose of Active Directory

-          Provides user logon and authentication services using Kerberos Protocol

-          To Centralized and Decentralized the resources management

-          To centrally organized and manage (User Account, Computer, Groups, Network Resources)

-          Enable authorized user to easily locate network resources.

Structure of Active Directory

-          Logical Structure

Ø  Domain

Ø  Tree

·         Parent / Root

·         Child / Branch

Ø  Forest

-          Physical

Ø  Domain Controllers

Ø  Sites
