Windows is an operating system for PCs (personal computers). The operating system is the software that organizes and controls all of the components (hardware and software) in your computer so that they integrate and work efficiently together.
The first operating system from Microsoft was known as MSDOS (Microsoft Disk Operating System). This was a nongraphical, line-oriented, command-driven operating system, able to run only one application at a time.
The original Windows system was an interface manager that ran on top of the MS-DOS system, providing a graphical user interface and using clever processor and memory management to allow it to run more than one application or function at a time.
The basic element of Windows was its “windowing” capability. A window (with a lower-case w) is a rectangular area used to display information or to run a program. Several windows can be opened at the same time so that you can work with multiple applications. Thisprovided a dramatic increase in productivity when using PCs, in comparison with the original MS-DOS.
Microsoft released several versions of this interface management Windows, with numerous intermediate versions, including:
1985 – Windows 1.0.
| |
1987 – Windows 2.0, 2.1 and 2.11.
| |
1990 – Windows 3.0, 3.1, 3.11 (Windows for Workgroups) .
| |
1995 – Windows 95, 98, 98 SE and Me (Millennium Edition)
The next version, Windows XP, was a full operating system in its own right. This was eventually followed by Windows Vista
| |
2001 – Windows XP (eXPerience) Home and Professional.
| |
2007 – Windows Vista Home, Home Premium, Ultimate etc.
| |
2009 – Windows 7 Starter, Home Premium, Ultimate etc.
| |
2012 – Windows 8, Pro, RT.
2014 – Windows 8.1, Pro, Enterprise, Core, RT.
| |
2015 29 July - Windows 10 (Date declared by Microsoft on june)
|
There have also been versions of Windows aimed specifically at businesses, including Windows NT, Windows 2000, Windows 2003 and Windows 2008.
Windows XP and later versions no longer incorporate MS-DOS, though they do still feature a Command Prompt that permits DOS-like command line functions.
The Windows logo has also been redesigned, to make it look more like a window and less like a flag, as in previous versions.
