1. Why windows server 2008 comes in different versions? What is the significance of each version? * I think Windows Server 2008 comes in several different versions, is to accommodate features useful to different types of users. For example: Larger business would want to have operating systems that can support many processors, and thousands of user. On the other hand small business may need operating system that supports limited web server and can support handful of users. Same for personal users, some people play lots of games and some are on the computer a lot, they may want operating system that can support games, have larger memory etc. Some personal user may want operating system that supports just basic. * Windows Server 2008 Standard.

Windows Server 2008 Standard is one of Microsoft's entry level server offerings (alongside Windows Web Server 2008) and is one of the least expensive of the various editions available. Both 32-bit and 64-bit versions are available, and in terms of hardware Standard Edition supports up to 4GB of RAM and 4 processors. Windows Server 2008 is primarily targeted for small and mid-sized businesses (SMBs) and is ideal for providing domain, web, DNS, remote access, print, file and application services. Support for clustering, however, is notably absent from this edition. An upgrade path to Windows Server 2008 Standard is available from Windows 2000 Server and Windows Server 2003 Standard Edition. * Windows Server 2008 Enterprise Edition.

Windows Server 2008 Enterprise Edition provides greater functionality and scalability than the Standard Edition. As with Standard Edition both 32-bit and 64-bit versions are available. Enhancements include support for as many as 8 processors and up to 64GB of RAM on 32-bit systems and 2TB of RAM on 64-bit systems. Additional features of the Enterprise edition include support for clusters of up to 8 nodes and Active Directory Federated Services (AD FS). Windows Server 2000, Windows 2000 Advanced Server, Windows Server 2003 Standard Edition and Windows Server 2003 Enterprise Edition may all be upgraded to Windows Server 2008 Enterprise Edition. * The Windows Server 2008 Datacenter edition.

The Datacenter edition represents the top end of the Windows Server 2008 product range and is targeted at mission critical enterprises requiring stability and high uptime levels. Windows Server 2008 Datacenter edition is tied closely to the underlying hardware through the implementation of custom Hardware Abstraction Layers (HAL). As such, it is currently only possible to obtain Datacenter edition as part of a hardware purchase. As with other versions, the Datacenter edition is available in 32-bit and 64-bit versions and supports 64GB of RAM on 32-bit systems and up to 2TB of RAM on 64-bit systems. In addition, this edition supports a minimum of 8 processors up to a maximum of 64. Upgrade paths to Windows Server 2008 Datacenter Edition are available from the Datacenter editions of Windows 2000 and 2003 * Windows Web Server 2008.

Windows Web Server 2008 is essentially a version of Windows Server 2008 designed primarily for the purpose of providing web services. It includes Internet Information Services (IIS) 7.0 along with associated services such as Simple Mail Transfer Protocol (SMTP) and Telnet. It is available in 32-bit and 64-bit versions and supports up to 4 processors. RAM is limited to 4GB and 32GB on 32-bit and 64-bit systems respectively. Windows Web Server 2008 lacks many of the features present in other editions such as clustering, BitLocker drive encryption, multipath I/O, Windows Internet Naming Service (WINS), Removable Storage Management and SAN Management. 2. What are the new features or enhancement made to Windows Server 2008?How is Windows Server 2008 different from Windows Server 2003?
