Virtualization is the ability to install and run multiple operating systems concurrently on a single physical machine. Most virtualization solutions include the following components:
Component | Description |
Physical Machine | A physical machine contains the actual system hardware, such as the hard disk drive(s), optical drive, RAM, processors, etc. |
Hypervisor | A hypervisor is a thin layer of software that resides between the virtual operating system(s) and the hardware. A hypervisor allows virtual machines to interact with the hardware without going through the host operating system. A hypervisor manages access to system resources such as:
Commonly used hypervisor types include:
|
Virtual Machine | A virtual machine is a software implementation of a computer that executes programs like a physical machine. The virtual machine appears to be a self-contained and autonomous system. |
Virtual Hard Disk (VHD) | A virtual hard disk (VHD) is a file that is created within the host operating system and that simulates a hard disk for the virtual machine. Different hypervisors use different virtual hard disk file formats:
|
Types of virtualization include the following:
Type | Description |
Full | In full virtualization, the virtual machine completely simulates a real physical host. This allows most operating systems and applications to run within the virtual machine without being modified in any way. |
Partial | In partial virtualization, only some of the components of the virtual machine are virtualized. Be aware of the following:
|
Para-virtualization | In para-virtualization, the hardware is not virtualized. Be aware of the following:

Active Directory is a centralized database that contains user account and security information. In a workgroup environment, authentication, security, and management all take place on each individual computer, with each device independently storing information about users and configuration settings. Using Active Directory, all computers share the same central authentication and configuration database.
An Active Directory implementation uses the following components:
Component | Description |
Trees and Forests | Multiple domains are grouped together in the following relationship:
|
Domain | A domain is an administratively-defined collection of network resources that share a common directory database and security policies. The domain is the basic administrative unit of an Active Directory structure.
Depending on the network structure and requirements, the entire network might be represented by a single domain with millions of objects, or the network might require multiple domains. |
Organizational Unit (OU) | An organizational unit is like a folder that subdivides and organizes network resources within a domain. An organizational unit:
|
Built-in Containers | Like OUs, generic built-in containers are used to organize Active Directory objects. However, built-in container objects have several differences:
|
Objects | Within Active Directory, each resource is identified as an object. Common objects include:
You should know the following about objects:
|
Domain Controller | A domain controller is a Windows server that holds a copy of the Active Directory database.
|
The Active Directory database resides in a file, called Ntds.dit, on the domain controller. This file stores all Active Directory data.
