Microsoft Windows originated as a graphical interface for MS-DOS and is now based on the Windows NT core. Windows runs on 32-bit and 64-bit Intel and AMD computers and holds around 90% of the worldwide desktop market share, though this is declining with open source alternatives growing in popularity. It is commonly used on servers for applications like web and database servers, and Microsoft has worked to demonstrate Windows can run any enterprise application.

![Microsoft Windows
The Microsoft Windows family of operating systems originated as a graphical layer on top of
the older MS-DOS environment for the IBM PC. Modern versions are based on the newer
Windows
NT core that first took shape in OS/2 and borrowed from OpenVMS. Windows runs on 32-bit
and
64-bit Intel and AMD computers, although earlier versions also ran on the DEC Alpha, MIPS,
and
PowerPC architectures (some work was done to port it to the SPARC architecture).
As of 2004, Windows held a near-monopoly of around 90% of the worldwide desktop market
share,
although this is thought to be dwindling due to the increase of interest focused on open source
operating systems. [1] It is also used on low-end and mid-range servers, supporting
applications
such as web servers and database servers. In recent years, Microsoft has spent significant
marketing and R&D money to demonstrate that Windows is capable of running any enterprise
application (see
the TPC article).](https://image.slidesharecdn.com/microsoftwindows-130302001004-phpapp01/85/Microsoft-windows-1-320.jpg)

Unix
Unix-like refers to a diverse family of operating systems that are similar to the original Unix system. This includes major subcategories like System V, BSD, and Linux. Unix systems run on a variety of hardware and are commonly used as servers in business and for workstations in academic and engineering environments. Free and open source Unix variants like Linux and BSD are increasingly popular for both servers and desktops. Over time, free Unix systems have replaced many proprietary Unix systems for tasks like scientific modeling and computer animation.
Disk Operating systems
The document discusses several disk operating systems including:
- MS-DOS and PC-DOS, which dominated the IBM PC compatible market from the 1980s to mid-1990s.
- 86-DOS, which was the predecessor to PC-DOS and MS-DOS.
- DR-DOS, a DOS clone developed by Digital Research as an alternative to MS-DOS.
- FreeDOS, an open-source operating system compatible with the DOS architecture and API.
Case study
MS-DOS was one of the most successful operating systems and was the first widely used operating system for IBM PCs and clones. It originated as QDOS, an operating system written in six weeks for the Intel 8086 CPU. Microsoft acquired QDOS and renamed it MS-DOS, which it licensed to IBM for use on the original IBM PC. MS-DOS went on to fuel Microsoft's growth as the dominant software company. While feature-limited compared to UNIX, MS-DOS remained popular for years until the rise of graphical user interfaces led to its replacement by Windows 95.

Mainframe and Midrange Migration according to Microsoft
Microsoft has created the Platform Modernization Alliance (PMA) to encourage customers running applications on IBM i, AIX, Solaris, mainframe, and OpenVMS servers to migrate them to Windows-based servers. The PMA aims to provide collaboration, education, marketing support and execute modernization projects through partnerships between Microsoft and over 60 technology providers. While past programs from Microsoft used fear and uncertainty tactics, the PMA takes a more practical approach by offering expertise, resources and events to help customers with modernization. Microsoft sees significant growth in migrations from platforms like IBM mainframe to Windows through the PMA partner ecosystem.
History of operating systems
An operating system (OS) manages computer hardware and software resources, performing tasks like memory management, process scheduling, and file management. Early computers did not have operating systems, but tools for system management emerged quickly. Major concepts in OS development included supporting an entire product line with a single OS, like IBM's OS/360, and time-sharing, which allowed multiple users to share expensive computers simultaneously. As microcomputers evolved, minimal OSes were developed for early models, while MS-DOS became widely popular through its inclusion with the IBM PC. By the 1990s, more robust OSes with graphical user interfaces became desirable, leading Microsoft and Apple to develop Windows NT and Mac OS X respectively based on Unix.

Classes B and C override this method by defining their own getB() and getC() methods, with B calling the superclass method and both printing additional messages. The main method creates instances of B and C and calls their respective methods to demonstrate method overriding.
How to achieve multiple inheritances by using interface in java
This document discusses how to achieve multiple inheritance in Java using interfaces. It defines two interfaces, Father and Mother, that each contain a float variable and method to get height. A Child class implements both interfaces and overrides the height method to calculate and print the average height from the interfaces. The code is tested in a main method that creates a Child object and calls its height method.
Method overriding in java
This Java program demonstrates method overriding. It defines a wallet class with dimensions and a salary method that returns 0. Monthly and annual classes extend wallet, overriding the salary method to return the product of the dimensions, and printing the appropriate salary text. The main method creates instances of each class, assigns them to a wallet reference variable, and calls salary to print the results.
WAP to implement inheritance and overloading methods in java
This document contains code that implements inheritance and method overloading. It defines a base mob class with getmob and putmob methods to retrieve and display student roll number and name. The drive class inherits from mob and overloads getdrive and putdrive methods to also retrieve and display subject marks. The pen class inherits from drive and overloads getresult and putresult methods to calculate and display the total marks. The main method creates a pen object and calls its methods.
program on Function overloading in java
The document defines a Sum class with three overloaded add() methods that take in different parameter types (two ints, three ints, and an int and float) and return the sum. It then creates a main method in an Overloading class that creates a Sum object and calls each add() method, passing different parameters to demonstrate function overloading.
Program on usage of Final keyword in java
The code defines a Bike class with a final integer field speedlimit that is initialized to 70 in the constructor. The main method creates a new Bike object, which prints out the maximum speed limit of 70.

Microsoft windows
- 1. Microsoft Windows The Microsoft Windows family of operating systems originated as a graphical layer on top of the older MS-DOS environment for the IBM PC. Modern versions are based on the newer Windows NT core that first took shape in OS/2 and borrowed from OpenVMS. Windows runs on 32-bit and 64-bit Intel and AMD computers, although earlier versions also ran on the DEC Alpha, MIPS, and PowerPC architectures (some work was done to port it to the SPARC architecture). As of 2004, Windows held a near-monopoly of around 90% of the worldwide desktop market share, although this is thought to be dwindling due to the increase of interest focused on open source operating systems. [1] It is also used on low-end and mid-range servers, supporting applications such as web servers and database servers. In recent years, Microsoft has spent significant marketing and R&D money to demonstrate that Windows is capable of running any enterprise application (see the TPC article).
