Windows

WindowsUnder Microsoft Windows one understands the generic term for the operating systems of the company Microsoft. Initially, Microsoft Windows should only be an extension of the MS-DOS operating system. Since the development branch was abolished to the benefit of the Windows NT product line, Windows refers to the entirety of all operating systems of the company. The name comes originally from the English language and means simply windows. The term is intended to be a transition to the user interface, which represents applications as rectangular windows.

product lines

The product line of the Windows range extends from the DOS line for 16-bit computers on the DOS line for 32-bit computers and the NT line to the CE line. The first product was released under the name Windows 1.0 in 1987 and is part of the DOS line for 16-bit computers. After the release of Windows 3.x and the development of 32-bit accesses, the name changed to Windows, which previously described only the graphical representation. The name established itself as the product name of the company.

DOS line for 32-bit computers

The following DOS line for 32-bit computers was originally based on the MS-DOS version. In contrast to this version, the so-called Windows 9x line has its own 32-bit kernel. Thanks to Virtual Device Driver, or VxDs, the kernel can control and coordinate system access after startup.

With Windows 95 Microsoft finally published in 1995 the first operating system, which was intended for home use. Since the concept was well received by users, Microsoft Windows 1998 released the next version called Windows 98 and in 2000 the version Windows ME.

NT line from Microsoft Windows

The special feature of the NT line is that all operating systems of this line have their own kernel. The abbreviation NT stands for New Technology and means analogously translated into German language „new technology“. Since version 5.0, the abbreviation is no longer used publicly. The new system was completely detached from the MD-DOS line, but was still able to run older 16-bit DOS programs in a virtual DOS machine.

Programs that previously had direct access to the system were abolished for security reasons. In addition, the command line interpreter named cmd.exe was introduced. Using the program, users of the operating system were able to make direct inputs to the system. The most recent version of the NT series is the Windows 7 operating system released in 2009.

Security of the operating systems

Because developers of malicious programs or computer viruses are particularly interested in the data of the end users, Windows is a popular target of hackers due to its high penetration among users. During the development of the NT line, the Internet became very popular as a medium, but it was fundamentally underestimated by the developers of the operating systems. For example, until the release of Windows Server 2003 it was possible to disable the security options without further restrictions.

Changes and improvements in internet security

Already in 2000, Microsoft released new updates on security, but these were not yet mature and protected only from minor malicious programs. Since 2003, when computer worm W32.Blaster attracted a lot of media attention, the company focused on cybersecurity with the release of Windows Vista. Of particular importance here was the introduction of user accounts. With Windows 7, the remaining gaps should be closed, making Windows operating systems the safest on the global market.
