Android is an operating system for mobile devices such as smartphones and tablet computers. It is developed by the Open Handset Alliance led by Google.

Google purchased the initial developer of the software, Android Inc., in 2005.The unveiling of the Android distribution on November 5, 2007 was announced with the founding of the Open Handset Alliance, a consortium of 84 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software license. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android..

Android consists of a kernel based on the Linux kernel, with middleware, libraries and APIs written in C and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik dex-code (Dalvik Executable), which is usually translated from Java bytecode.

Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Developers write primarily in a customized version of Java. There are currently approximately 400,000 apps available for Android, from a total of 600,000 apps over the life of Android. Apps can be downloaded from third-party sites or through online stores such as Android Market, the app store run by Google.

Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.

A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc. You dont need a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud ( internet) and is totally managed by the cloud service provider Yaho , Google etc. The consumer gets to use the software alone and enjoy the benefits. The analogy is , 'If you need milk , would you buy a cow ?' All the users or consumers need is to get the benefits of using the software or hardware of the computer like sending emails etc. Just to get this benefit (milk) why should a consumer buy a (cow) software /hardware ?

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a metered service over a network (typically the Internet).

A database software is a type of computer program that is designed to handle lots of data, but to store them in such a way that finding (and thus retrieving) any snippet of data is more efficient than it would have been if you simply dumped them willy nilly all over the place. With such database software, if you (say) keep a list of customers and their shipping addresses, entering and retrieving information about your one millionth customer will not take much longer (if at all) than entering and retrieving information about your 1st customer.

Database programs have many different methods for storing and retrieving data, as well as for organising the stored data on the computer. One popular way for accessing data, both to store and to retrieve it, is to use a computer language called "SQL" (often pronounced as "sequel"). SQL was specially designed for database access.

C# (pronounced "C-sharp") is an object-oriented programming language from Microsoft that aims to combine the computing power of C++ with the programming ease of Visual Basic. C# is based on C++ and contains features similar to those of Java.

C# is designed to work with Microsoft's .Net platform. Microsoft's aim is to facilitate the exchange of information and services over the Web, and to enable developers to build highly portable applications. C# simplifies programming through its use of Extensible Markup Language and Simple Object Access Protocol (SOAP) which allow access to a programming object or method without requiring the programmer to write additional code for each step. Because programmers can build on existing code, rather than repeatedly duplicating it, C# is expected to make it faster and less expensive to get new products and services to market.

• Hibernate is a powerful, high performance object/relational persistence and query service.
• Hibernate allows development of persistent classes following object-oriented idiom that includes association, inheritance, polymorphism, composition, and collections.
• Hibernate allows expressing queries in its own portable SQL extension (HQL), as well as in native SQL, or with an object-oriented Criteria and Example API.

When we write Java code, we create objects, and those objects have properties. Here's a simple piece of code. Just by looking at it, I think you can tell what the User's name and password are:

User user = new User();        //an object named user is created
user.setName("Cameron");       //name is initialized to Cameron
user.setPassword("n0tte11ing");//password is initialized to n0tte11ing

I think even the uninitiated Java programmer would recognize that we have just created a user named Cameron with a password of n0tte11ing. We see this type of object creation and property initialization in Java programs all the time. But the problem Java developers always have is figuring out how to take the data associated with the object and save it to the database. Hibernate makes the persistence of your Java objects, aka Java Persistence, easy.

Just how easy is it to persist Java objects with Hibernate?

With a magical and mystical object known as the Hibernate Session, persisting the state of your Java objects is easy. Look how readable and understandable the following code is:

User user = new User();        //an object named user is created
user.setName("Cameron");       //name is initialized to Cameron
user.setPassword("n0tte11ing");//password is initialized to n0tte11ing
Session hibernateSession = HibernateUtil.getSession(); 
                               //get the magical Hibernate session
hibernateSession.save(user);   //save the user to the database!

The line of code hibernateSession.save(user); saves the state of the user instance to the database. Of course, there's a little bit of plumbing code that needs to go in there to make the whole hibernate framework work; But setting up that plumbing code really isn't that bad. Overall, Hibernate is real easy to use, fairly easy to set up, and probably the easiest way to manage the persistent state of you domain model objects.

1.Struts is a web page development framework and an open source software that helps developers build web applications quickly and easily. Struts combines Java Servlets, Java Server Pages, custom tags, and message resources into a unified framework. It is a cooperative, synergistic platform, suitable for development teams, independent developers, and everyone between.

2.The core of the Struts framework is a flexible control layer based on standard technologies like Java Servlets, JavaBeans, ResourceBundles, and XML, as well as various Jakarta Commons packages. Struts encourages application architectures based on the Model 2 approach, a variation of the classic Model-View-Controller (MVC) design paradigm. Struts provides its own Controller component and integrates with other technologies to provide the Model and the View. For the Model, Struts can interact with standard data access technologies, like JDBC and EJB, as well as most any third-party packages, like Hibernate, iBATIS, or Object Relational Bridge. For the View, Struts works well with JavaServer Pages, including JSTL and JSF, as well as Velocity Templates, XSLT, and other presentation systems. The Struts framework provides the invisible underpinnings every professional web application needs to survive. Struts helps you create an extensible development environment for your application, based on published standards and proven design patterns.

3. truts Frame work is the implementation of Model-View-Controller (MVC) design pattern for the JSP. Struts is maintained as a part of Apache Jakarta project and is open source. Struts Framework is suited for the application of any size. Latest version of struts can be downloaded from http://jakarta.apache.org/.

About Ubuntu

Linux was already established as an enterprise server platform in 2004. But free software was still not a part of everyday life for most computer users. That's why Mark Shuttleworth gathered a small team of developers from one of the most established Linux projects – Debian - and set out to create an easy-to-use Linux desktop, Ubuntu.

The vision for Ubuntu is part social and part economic: free software, available free of charge to everybody on the same terms, and funded through a portfolio of services provided by Canonical.

 The first version of Ubuntu was based on the GNOME desktop. We have since added a KDE edition, Kubuntu, and a server edition. All of the editions of Ubuntu share common infrastructure and software, making Ubuntu a unique platform that scales from consumer electronics to the desktop, and into the cloud for enterprise computing. Developers can work on their desktop of choice, and smoothly deliver code to cloud servers running the stripped-down Ubuntu Server Edition.

In recent years, special emphasis has been placed on netbooks for lightweight, connected, mobile computing, and on the cloud as a new architecture for data centres. Ubuntu is a pioneer in both fields, with Ubuntu Netbook Edition and Ubuntu Enterprise Cloud setting the standard for easy deployment and management. Ubuntu is hugely popular on Amazon's EC2 and Rackspace's Cloud, and is pre-installed on computers from Dell, Lenovo and other global vendors.

Ubuntu still is and always will be free to use, share and develop. We hope it will bring a touch of light to your computing – and we hope that you'll join us in helping to build the next version too.
