An operating system "OS" or "DOS"

Operating Systems Means, Tips & Tools.Microsoft Windows Server 2008 is the company's latest server operating system. Officially launched in February 2008, Windows Server 2008 is the successor to Microsoft's previous server OS, Windows Server 2003.
"The other is Disk Operating System, in a general sense, DOS refers to just about any operating system. More commonly, it describes the operating system Microsoft developed in 1981 for IBM's line of personal computers. Though syntactically distinct, DOS shares similarities with a Unix shell. It has a command-line interface and analogs to many common Unix commands. However, DOS is a 16-bit, single-user operating system that does not support multi-tasking. It is far easier to administer than Unix, but less powerful. Compared to graphical interfaces such as Windows and Mac OS X, it's also not particularly user-friendly."
An operating system sometimes abbreviated as "OS".Operating System is the program that being initially loaded into the computer by a boot program or manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).
An operating system performs these services for applications:

  1. In a multitasking operating system where multiple programs can be running at the same time, the operating system determines which applications should run in what order and how much time should be allowed for each application before giving another application a turn.
  2. It manages the sharing of internal memory among multiple applications.
  3. It handles input and output to and from attached hardware devices, such as hard disks, printers, and dial-up ports.
  4. It sends messages to each application or interactive user (or to a system operator) about the status of operation and any errors that may have occurred.
  5. It can offload the management of what are called batch jobs (for example, printing) so that the initiating application is freed from this work.
  6. On computers that can provide parallel processing, an operating system can manage how to divide the program so that it runs on more than one processor at a time.
All major computer platforms (hardware and software) require and sometimes include an operating system. Linux, Windows 2000, VMS, OS/400, AIX, and z/OS are all examples of operating systems.

what is windows 2000?


Windows 2000 is a line of operating systems produced by Microsoft for use on personal computers, business desktops, laptops, and servers. Windows 2000 was released to manufacturing on 15th December 1999 [3] and launched to retail on 17 February 2000.[4] It is the successor to Windows NT 4.0, and is the final release of Microsoft Windows to display the "Windows NT" designation.[5] It was succeeded by Windows XP for desktop systems in October 2001 and Windows Server 2003 for servers in April 2003. Windows Me was released seven months after Windows 2000 and one year before Windows XP, but Windows Me was not intended to be, nor did it serve as the successor to Windows 2000. Windows Me was designed for home use, while Windows 2000 was designed for business.[6]
Four editions of Windows 2000 were released, listed here in increasing ranking: Professional, Server, Advanced Server, and Datacenter Server.[7] Additionally, Microsoft sold Windows 2000 Advanced Server Limited Edition and Windows 2000 Datacenter Server Limited Edition, which ran on 64-bit Intel Itanium microprocessors and were released in 2001.[8] While each edition of Windows 2000 was targeted at a different market, they shared a core set of features, including many system utilities such as the Microsoft Management Console and standard system administration applications.
Support for people with disabilities has been improved over Windows NT 4.0 with a number of new assistive technologies,[9] and Microsoft increased support for different languages[10] and locale information.[11]
All versions of the operating system support the Windows NT file system, NTFS 3.0,[12] the Encrypting File System, as well as basic and dynamic disk storage.[13] The Windows 2000 Server family has additional features,[14] including the ability to provide Active Directory services (a hierarchical framework of resources), Distributed File System (a file system that supports sharing of files) and fault-redundant storage volumes. Windows 2000 can be installed through either a manual or unattended installation.[15] Unattended installations rely on the use of answer files to fill in installation information, and can be performed through a bootable CD using Microsoft Systems Management Server, by the System Preparation Tool.[16]
Microsoft marketed Windows 2000 as the most secure Windows version ever at the time;[17] however, it became the target of a number of high-profile virus attacks such as Code Red and Nimda.[18] For ten years after its release, it continued to receive patches for security vulnerabilities nearly every month until reaching the end of its lifecycle on 13 July 2010.

differences between 2003 server and 2008 server


The main difference between 2003 and 2008 is Virtualization, management.

2008 has more inbuild components and updated third party drivers.

Note: Windows server 2008 45 time fast compare to win 2003.

In Windows Server 2008, Microsoft is introducing new features and technologies, some of which were not available in Windows Server 2003 with Service Pack 1 (SP1), that will help to reduce the power consumption of server and client operating systems, minimize environmental byproducts, and increase server efficiency.
Microsoft Windows Server 2008 has been designed with energy efficiency in mind, to provide customers with ready and convenient access to a number of new power-saving features. It includes updated support for Advanced Configuration and Power Interface (ACPI) processor power management (PPM) features, including support for processor performance states (P-states) and processor idle sleep states on multiprocessor systems. These features simplify power management in Windows Server 2008 (WS08) and can be managed easily across servers and clients using Group Policies.
Windows Server 2008 introduces Hyper-V (V for Virtualization) but only on 64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine. If you like this exciting technology, make sure that you buy an edition of Windows Server 2008 that includes Hyper-V, then launch the Server Manger, add Roles.

Windows Server 2008, formerly codenamed Longhorn, is no leas than 45 times faster than its predecessor, Windows Server 2003, in terms of network transfer speeds. Now whatever the perspective is on Microsoft's last 32-bit server operating system, the fact of the matter is that faster transfer speeds for of up to 45 times is quite an evolution compared to Windows Server 2003. Back in June 2007, Microsoft commissioned a study to the Tolly Group focused on the networking performances of its latest Windows client and server operating system, which ended up as the "Enhanced Network Performance with Microsoft Windows Vista and Windows Server 2008" whitepaper. The paper pointed to the fact that both Vista and Windows Server 2008 managed to offer "Dramatic network performance benefits".
