Web Technology Questions

XAML is a markup language used to define dynamic or static UIs for .NET applications. Though Windows Vista would be used to design XAML UIs, they can be applied to Windows XP or Windows 2003 too.

XAML is similar to MVC in terms of the separation of the UI code from application logic.

XAML is bound to Windows Presentation foundation to build a UI in .NET 3.0 and Windows Vista.

XAML Features:

- XAML inherits all XML definitions and rules.

- It also contains HTML, XHTML and other markup languages for UI.

- Every XAML element represents a .NET CLR class due to which working with XAML becomes simple.

- The application logic can be put in a separate file or be embedded in XAML file itself as XAML in conjunction with Windows Presentation Foundation model to provide the developers design a good UI in ASP.NET.

- XAML files get compiled to BAML files which are smaller than XAML and easier to read which make them faster to load.

- Files can be transferred to the server by using the FTP protocol also known as File Transfer Protocol. 

- FTP is used as a standard network protocol that transfers the file from one computer to another computer using the TCP protocol network.

- This uploads the pages and other documents that are stored in private disk to the public web hosting server. 

- FTP is used on a client server architecture that allows different controls and data connections between the client and the server. 

- FTP uses clear-text sign in protocol that allows the client to use the user name and password for authentication purpose.

Number, String, Boolean, Function, Object, Null, Undefined.

- Frames make it easier to navigate through a site. 

- The links that appear in the frame can appear through out the site.

=> Once the product is selected, the consumer transaction is moved to the online transaction server where he places an order. 

=> The informations is exchanged over a secure channel through a private gateway to a processing network. 

=> The networked banks accept or reject the transaction.

 All this happens in just a matter of seconds. E-commerce is a very secure due to the SSL (Secure Socket Layer) technology.

CDATA - (Unparsed) Character Data

The term CDATA is used when you dont want some text data to be parsed by the XML parser.

A CDATA section starts with "<![CDATA[" and ends with "]]>": 

- The principle of least privilege is used to provide more security to the computer programs. 

- The principle allows the designing of the program such that any unauthorized access is not allowed and only the person who owns the program will be able to access it. 

- The services provided should be able to access only those products that need the services. 

- Web servers that are involved in responding the queries of the web users provide only accessing to the HTML files that will serve the purpose of the programs. 

- Computer programs should be made such that it provides secure features of logging into the program with proper authentication.
