Technology Questions

Android uses Dalvik Virtual Machine (DVM) which requires a special bytecode. We need to convert Java class files into Dalvik Executable files using an Android tool called "dx". In normal circumstances, developers will not be using this tool directly and build tools will care for the generation of DVM compatible files.

Web application provides services (Free and Paid) apart from information.

With HTML5, it is possible for the web pages to store the data locally in the user's browser. This web storage is much faster and secured than the cookies. Also, a larger amount of data can be stored without causing any adverse effect to the performance of the website. 

The data here is not included with every server request. It is used ONLY when it is asked for. It is only that particular web page that can access the data stored by itself.

XML, Extensible Markup Language, is an open, text based markup language that provides structural and semantic information to data. XML is a metalanguage that can be used to create other language. It is used to structure and describe data that can be understood by other applications. Using XML, we can separate the user interface from data.

Features of XML :

- XML is a generalized markup language that means one can define his/her own tag sets.

- A valid XML document contains rules and is self-describing.

- The rules that are found in DTD allow the documents to be validated.

For web application we perform following time of test:

1. Functionality Testing.

2. Usability Testing.

3. Navigation Testing.

4. Configuration and Compatibility testing.

5. Reliability and Availability Testing.

6. Performance Testing.

7. Load and Stress Testing.

8. Security Testing

Microsoft security patches are intended to solve certain security loopholes and problems, while at the same time upgrading any existing security features. This would provide better protection by reducing vulnerabilities in security.

iPhone responds to motion using a built-in accelerometer.
The accelerometer detects the movement and changes the display accordingly, at the time of rotating iPhone from portrait to landscape.
