2. Several Operating Systems available in the world:
   1. PC – Windows
      Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft.Microsoft introduced an operating environment named Windows on November 20, 1985 as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI). Microsoft Windows came to dominate the world’s personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984.As of October 2013, the most recent versions of Windows for personal computers, mobile devices, server computers and embedded devices are respectively Windows 8.1, Windows Phone 8, Windows Server 2012 R2 and Windows Embedded 8.Windows 8 is a personal computer operating system developed by Microsoft as part of Windows NT family of operating systems. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. It was announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.Windows 8 introduced major changes to the operating system’s platform and user interface to improve its user experience on tablets, where Windows was now competing with mobile operating systems, including Android and iOS. In particular, these changes included a touch-optimized Windows shell based on Microsoft’s “Metro” design language, the Start screen (which displays programs and dynamically updated content on a grid of tiles), a new platform for developing apps with an emphasis on touchscreen input, integration with online services (including the ability to sync apps and settings between devices), and Windows Store, an online store for downloading and purchasing new software. Windows 8 added support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware, to prevent malware from infecting the boot process. 
   2. PC – OS XOS X, previously Mac OS X, is a series of Unix-based graphical interface operating systems developed, marketed, and sold by Apple Inc. It is designed to run exclusively on Mac computers, having been pre-loaded on all Macs since 2002. It was the successor to Mac OS 9, released in 1999, the final release of the “classic” Mac OS, which had been Apple’s primary operating system since 1984. The first version released was Mac OS X Server 1.0 in 1999, and a desktop version, Mac OS X v10.0 “Cheetah” followed on March 24, 2001. Previous releases of OS X were named after big cats; for example, OS X v10.8 was referred to as “Mountain Lion”. However, with the announcement of OS X Mavericks this was dropped in favor of Californian landmarks. 
   3. PC, Server – LinuxLinux is a Unix-like and POSIX-compliant computer operating system assembled under the model of free and open source software development and distribution. The main form of distribution are Linux distributions. The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991, by Linus Torvalds. Because it considers Linux to be a variant of the GNU operating system, initiated in 1983 by Richard Stallman, the Free Software Foundation prefers the name GNU/Linux when referring to the operating system as a whole.Linux was originally developed as a free operating system for Intel x86-based personal computers. It has since been ported to more computer hardware platforms than any other operating system. It is a leading operating system on servers and other big iron systems such as mainframe computers and supercomputers: as of June 2013, more than 95% of the world’s 500 fastest supercomputers run some variant of Linux, including all the 44 fastest. Linux also runs on embedded systems (devices where the operating system is typically built into the firmware and highly tailored to the system) such as mobile phones, tablet computers, network routers, building automation controls, televisions and video game consoles; the Android system in wide use on mobile devices is built on the Linux kernel. 
   4. Server – Windows ServerWindows Server is a brand name for a group of server operating systems released by Microsoft Corporation.Windows Server 2012, codenamed “Windows Server 8″, is the sixth release of Windows Server. It is the server version of Windows 8 and succeeds Windows Server 2008 R2. Two pre-release versions, a developer preview and a beta version, were released during development. The software was generally available to customers starting on September 4, 2012.Unlike its predecessor, Windows Server 2012 has no support for Itanium-based computers, and has four editions. Various features were added or improved over Windows Server 2008 R2 (with many placing an emphasis on cloud computing), such as an updated version of Hyper-V, an IP address management role, a new version of Windows Task Manager, and ReFS, a new file system. Windows Server 2012 received generally good reviews in spite of having included the same controversial Metro-based user interface seen in Windows 8. 
   5. Server – OS X ServerThe server edition, OS X Server, was architecturally identical to its desktop counterpart, and included tools to facilitate management of workgroups of OS X machines, and to provide network services. Starting with v10.7 “Lion”, OS X Server is no longer offered as a separate operating system product; instead, the server management tools are available for purchase separately, and are preloaded on the server models of Mac Pro and Mac Mini along with OS X. 
   6. Mobile – Windows PhoneWindows Phone (abbreviated as WP) is a series of proprietary smartphone operating systems developed by Microsoft. It is the successor to Windows Mobile, although it is incompatible with the earlier platform. Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010, with a release in Asia following in early 2011.The latest release is Windows Phone 8, which was launched on October 29, 2012. With Windows Phone, Microsoft created a new user interface, featuring a design language named “Modern” (which was formerly known as “Metro”). Additionally, the software is integrated with third-party and Microsoft services, and sets minimum requirements for the hardware on which it runs. 
   7. Mobile – iOSiOS (previously iPhone OS) is a mobile operating system developed and distributed by Apple Inc. Originally unveiled in 2007 for the iPhone, it has been extended to support other Apple devices such as the iPod Touch (September 2007), iPad (January 2010), iPad Mini (November 2012) and second-generation Apple TV (September 2010). Unlike Microsoft’s Windows Phone and Google’s Android, Apple does not license iOS for installation on non-Apple hardware. As of October 2013, Apple’s App Store contained more than 1 million iOS applications, 475,000 of which were optimised for iPad. These apps have collectively been downloaded more than 60 billion times. It had a 21% share of the smartphone mobile operating system units shipped in the fourth quarter of 2012, behind only Google’s Android. In June 2012, it accounted for 65% of mobile web data consumption (including use on both the iPod Touch and the iPad). At the half of 2012, there were 410 million devices activated.The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching from portrait to landscape mode).iOS is derived from OS X, with which it shares the Darwin foundation and various application frameworks. iOS is Apple’s mobile version of the OS X operating system used on Apple computers. 
   8. Mobile – AndroidAndroid is an operating system based on the Linux kernel, and designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first Android-powered phone was sold in October 2008.The user interface of Android is based off direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented. Android allows users to customize their homescreens with shortcuts to applications and widgets, which allow users to display live content, such as emails and weather information, directly on the homescreen. Applications can further send notifications to the user to inform them of relevant information, such as new emails and text messages.
