The oldest of all Microsoft’s operating systems is MS-DOS (Microsoft Disk Operating System). MS-DOS is a text-based operating system. Users have to type commands rather than use the more friendly graphical user interfaces (GUI’s) available today. Despite its very basic appearance, MS-DOS is a very powerful operating system. There are many advanced applications and games available for MS-DOS. A version of MS-DOS underpins Windows. Many advanced administration tasks in Windows can only be performed using MS-DOS.
Introduction To WindowsThe history of Microsoft Windows dates back to 1985, when Microsoft released Microsoft Windows Version 1.01. Microsoft’s aim was to provide a friendly user-interface known as a GUI (graphical user interface) which allowed for easier navigation of the system features. Windows 1.01 never really caught on. (The amazing thing about Windows 1.01 is that it fitted on a single floppy disk!). In 1987 Microsoft revamped the operating system and released Windows 2.03. The GUI was very slightly improved but still looked too similar to Windows 1.01. The operating system again failed to capture a wide audience.
Microsoft made an enormous impression with Windows 3.0 and 3.1. Graphics and functionality were drastically improved. The Windows 3.x family provided multimedia capabilities as well as vastly improved graphics and application support.
Building on the success of Windows 3.x, Microsoft released Microsoft Windows For Workgroups 3.11. This gave Windows the ability to function on a network. It is not uncommon to find companies still using Windows 3.11.
In 1993 Microsoft divided the operating system into two categories; Business and home user. Windows NT (New Technology) was a lot more reliable than Windows 3.x. Windows NT provided advanced network features. On the business front, Windows NT continued to develop with the release of version 3.51. Different versions were provided which offered
