UBUNTU -OPEN SOURCE OPERATING SYSTEM

Ubuntu  is a computer operating system based on the Debian Linux distribution and distributed as free and open source software, using its own desktop environment. It is named after the Southern African philosophy of ubuntu ("humanity towards others") or another translation would be: "the belief in a universal bond of sharing that connects all humanity". 

As of 2012, according to online surveys, Ubuntu is the most popular Linux distribution on desktop/laptop personal computers, and most Ubuntu coverage focuses on its use in that market. However, it is also popular on serversand for cloud computing.^{[citation needed]}

Development of Ubuntu is led by Canonical, Ltd., a UK-based company owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and services related to Ubuntu, and since version 12.10, by displaying advertisements in Unity Dash, the default file manager in desktop Ubuntu.According to Canonical, the Ubuntu project is committed to the principles of free software development; people are encouraged to use free software, improve it, and distribute it.

AN INTRO ABOUT WINDOWS PHONE 8.0:

• Windows Phone 8 is the second generation of the Windows Phone mobile operating system from Microsoft. It was released on October 29th, 2012, and like its predecessor, it features the interface known as Metro (or Modern UI).
• Windows Phone 8 replaces its CE-based architecture used on Windows Phone 7 devices with the Windows NT kernel found on many Windows 8 components. Current Windows Phone 7.x devices cannot run or update to Windows Phone 8 and new applications compiled specifically for Windows Phone 8 are not made available for Windows Phone 7.x devices.[2]
• Windows Phone 8 is the first mobile OS from Microsoft to use the Windows NT kernel, which is the same kernel that runs Windows 8. The operating system adds improved file system, drivers, network stack, security components, media and graphics support. Using the NT kernel, Windows Phone can now support multi-core CPUs of up to 64 cores, as well as 1280x720 and 1280x768 resolutions, in addition to the base 800x480 resolution already available on Windows Phone 7. Furthermore, Windows Phone 8 also adds support for MicroSD cards, which are commonly used to add extra storage to phones.
• Due to the switch to the NT kernel, Windows Phone 8 also supports native 128-bit Bitlocker encryption and Secure Boot. Windows Phone 8 also supports NTFS file system due to this switch.[10]

• Other Features:

• Xbox SmartGlass allows control of an Xbox 360 with a phone (Available for Windows Phone, iOS and Android)
• Xbox Music services support playback audio files in Windows Phone, as well as music purchases.
• Xbox Video services support playback of video files in Windows Phone but not video purchases. [14]
• Native code support (C++), allows for simplified porting from platforms such as Android, Symbian, and iOS
• Simplified porting of Windows 8 apps to Windows Phone 8 (compatibility with Windows 8 "Modern UI" apps)
• Remote device management of Windows Phone similar to management of Windows PCs
• VoIP and video chat integration for any VoIP or video chat app (integrates into the phone dialer, people hub)
• Firmware over the air for Windows Phone updates
• Minimum 18 month support of Windows Phone updates to Windows Phone 8 devices
• Camera app now supports "lenses", which allow third parties to skin and add features to camera interface
• Native screen capture is added by pressing home and power buttons simultaneously
• Hebrew language support is added for Microsoft to introduce Windows Phone to the Israeli market.[15]

 A SMALL INTRODUCTION ABOUT C#  LANGUAGE:

            C#(pronounced see sharp) is a multi-paradigm programming language encompassing strong typing,             imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.

•  It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006). C# is one of the programming languages designed for the Common Language Infrastructure.

C# is intended to be a simple, modern, general-purpose, object-oriented programming language.[6] Its development team is led by Anders Hejlsberg. The most recent version is C# 5.0, which was released on August 15, 2012.

Design goals:

 The ECMA standard lists these design goals for C#:[6]
The C# language is intended to be a simple, modern, general-purpose, object-oriented programming language.
The language, and implementations thereof, should provide support for software engineering principles such as strong type checking, array bounds checking, detection of attempts to use uninitialized variables, and automatic garbage collection.
Software robustness, durability, and programmer productivity are important.
The language is intended for use in developing software components suitable for deployment in distributed environments.
Source code portability is very important, as is programmer portability, especially for those programmers already familiar with C and C++.
Support for internationalization is very important.
C# is intended to be suitable for writing applications for both hosted and embedded systems, ranging from the very large that use sophisticated operating systems, down to the very small having dedicated functions.

Although C# applications are intended to be economical with regard to memory and processing power requirements, the language was not intended to compete directly on performance and size with C or assembly language.

Reason for name c#:

The name "C sharp" was inspired by musical notation where a sharp indicates that the written note should be made a semitone higher in pitch. This is similar to the language name of C++, where "++" indicates that a variable should be incremented by 1.

ADVANTAGE OF USING WINDOWS-8:

1. Quick Boot: This is a feature I love. Instead of turning on the computer and waiting for it to boot for long, I now get to the Start screen within 10 seconds. That is on a Celeron powered notebook!!!

2. Shutdown: It seems as quick as pressing the POWER button in old 8086 machines running MS-DOS (Remember them?)

3. Boot to Internet ready Interface: Unlike Windows 7 that shows desktop while still loading drivers for Internet, I can fire Internet as soon as I get to the start screen. No waiting here as well.

4. Navigation: Strange enough, I am not missing the Start menu nor the Start screen. Scrolling using the mouse wheel is fun. It is a different matter that I removed all unnecessary apps to make it a smaller scroll.
