Windows CE
"
32-bit operating system
"
Supports new types of hardware
"
Provides high performance with limited hardware
"
Useful for mobile workers and applications
Microsoft Windows
®
CE is a 32-bit multitasking, multithreaded operating
system. It provides many of the operating system features of Windows 95,
Windows 98, and Windows NT
®
to a much smaller platform and allows the
developer to provide much greater functionality in applications that run on
extremely small computer platforms.
Windows CE supports newer, smaller types of hardware such as handheld
computers. In addition, Windows CE provides the potential for having full
applications available with other types of devices, such as televisions or DVD
players. Because Windows CE can communicate with other Windows operating
systems, there is a potential for many new products and services.
The design of Windows CE also allows it to perform well on limited hardware.
Many small computers simply do not have the memory or secondary storage
available for a Windows 95, Windows 98, or Windows NT operating system.
However, Windows CE was designed for a limited-hardware environment.
Windows CE fits well into a solution that requires high mobility. For example,
Windows CE devices are appropriate for e-mail notification, reading reports, or
submitting forms such as purchase requests.
Slide Objective
To explain the beneficial
features of the Windows CE
operating system.
Lead-in
Windows CE is designed for
small, extremely portable
devices.

Windows 95/98
"
Backward compatible with legacy hardware
"
Basic security
"
Requires less hardware to perform well
"
Large existing install base
"
Support for COM components
Windows 95/98 is the direct successor to the Windows 3.1 platform. The large
number of hardware devices that are supported by the operating system
simplifies deploying Windows 95/98. Many environments have a large number
of legacy hardware devices that may not be supported by other operating
systems.
Windows 95/98 provides a basic security system for allowing users to log on to
a network by using a user ID and password. However, the security of resources
within the operating system itself is fairly limited.
Windows 95/98 has smaller hardware resource requirements than other
operating systems. For example, Windows 95/98 requires less memory than
Windows NT Workstation.
Finally, Windows 95/98 is fairly mature and has a large existing install base.
This translates into a large pool of technicians who are familiar with the
Windows 95/98 architecture and who can deal with problems effectively.
Finally, Windows 95/98 supports the use of Component Object Model (COM)
and DCOM components in applications and participates in Windows NT
networks.
Slide Objective
To explain the beneficial
features of the Windows
95/98 operating system.
Lead-in
Windows 95/98 is the direct
successor to the Windows
3.1 platform.

Windows NT Workstation
"
32-bit multithreading operating system
"
High-security architecture
"
Supports centralized management
"
Efficiently scales to high-performance hardware
Windows NT Workstation is a 32-bit multithreading operating system. Its
architecture enables the operating system to control access to resources and
supports greater reliability. The operating system, not the applications, is
responsible for multitasking, memory management, and resource access.
Windows NT Workstation is built with a high-security architecture. This
architecture includes the ability to control access at the file and object level to
individual users. Windows NT domain integration and auditing are also
available within the security systems of the operating system.
Windows NT Workstation also allows centralized administration. User IDs,
passwords, group memberships, and security settings can be centralized in a
Windows NT domain. Additionally, system policies allow the behavior of the
operating system, such as access to system settings, to be controlled from a
central location.
Windows NT Workstation scales well to support high-performance hardware. It
supports greater memory and dual-processor configurations for many
calculation, processor, or graphics-intensive applications that are beyond the
capabilities of Windows 95/98.
Slide Objective
To explain the beneficial
features of the Windows NT
Workstation operating
system.
Lead-in
Windows NT Workstation is
the desktop product for the
Windows NT family.

Enterprise Edition includes Windows NT Server benefits
"
Enterprise Edition is optimized for high-volume
application services
"
Enterprise Edition supports
clustering
Windows NT Server contains the same core functionality as Windows NT
Workstation. However, Windows NT Server contains additional benefits.
Windows NT Server is designed to support application services such as
database or messaging servers in a reliable manner.
Additional resources are often available to support and implement new
technologies and applications on the Windows NT platform.
The Option Pack for Windows NT Server provides several additional system
services such as Internet Information Services (IIS), Microsoft Transaction
Services (MTS), Message Queuing Services, and Indexing Services.
The most important advantage of Windows NT Server Enterprise Edition over
Windows NT Server is that it is optimized for high-volume application services.
Changes in the memory architecture allow for more scalability with
applications such as Microsoft SQL Server
™
.
Windows NT Server Enterprise Edition also supports system clustering.
Clustering allows another server to provide services if one server fails and helps
prevent unplanned outages.
Slide Objective
To explain the beneficial
features of the Windows NT
Server operating system.
Lead-in
Windows NT Server
contains the same core
functionality as Windows NT
Workstation but contains
additional features that

Windows 2000 Professional is the result of the evolution of Windows NT
Workstation. Window 2000 Professional contains all of the benefits of
Windows NT Workstation and provides additional benefits as well.
First, Windows 2000 Professional provides better hardware support than
Windows NT workstation. This enhanced support includes the ability to use
new hardware such as DVD drives and Plug and Play devices.
Additionally, Windows 2000 provides improved support for mobile users. New
features, such as enhanced PC-card and power-management support, allow
laptops to function well by using the advanced technologies of Windows NT.
Many of these technologies are especially useful to laptop users, such as the
enhanced security features.
Windows 2000 also supports Microsoft Active Directory
™
and the updated
security features that are detailed later in the module.

Additional application services
Windows 2000 Advanced Server is the result of the evolution of Windows NT
Server Enterprise Edition. It is built upon Windows 2000 Server but contains
additional benefits and features.
First, Windows 2000 Advanced Server allows for enhanced scalability. As
many as eight processors are supported for multiprocessor configurations,
which allows for high-end servers for high-throughput applications.
Windows 2000 Advanced Server also includes Windows clustering capabilities
for high reliability on mission-critical applications, as well as terminal services.

Guidelines
"
Deploy Windows NT or Windows 2000 for new hardware
"
Integrate Windows NT and Active Directory security
within your applications
"
Deploy Windows NT Enterprise Edition or Windows
2000 Advanced Server for high-volume, server-based
applications
Windows 2000 provides advanced features over the Windows 95 and Windows
98 platforms and provides a lower total cost of ownership. These features are
critical for the performance, reliability, and manageability of the workstations.
Unless there are legacy hardware or software restrictions that require Windows
95 or Windows 98, move forward with Windows 2000.
Active Directory serves as a central repository for directory and security
information. The project team should plan on supporting Active Directory
within new applications to take advantage of its storage capabilities and allow
the organization to move toward a single point of authentication and security.
Windows NT Enterprise Edition and Windows 2000 Advanced Server are well
suited for high-volume applications because of additional features such as
enhanced memory support and clustering.
