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. Module 9: Designing Solutions with Microsoft Technologies 283 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.

Lead-in Windows NT Workstation is the desktop product for the Windows NT family. 284 Module 9: Designing Solutions with Microsoft Technologies Windows NT Server and Enterprise Edition " Includes Windows NT Workstation benefits " Tuned for high data throughput and network performance " Application services for high-volume environments " Large install base and industry expertise " Application services " 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 make it suitable for a file or application server.
