Q:

What’s the difference between Enumeration and Iterator interfaces ?

Answer

Enumeration is twice as fast as compared to an Iterator and uses very less memory. However, the Iterator is much safer compared to Enumeration, because other threads are not able to modify the collection object that is currently traversed by the iterator. Also, Iteratorsallow the caller to remove elements from the underlying collection, something which is not possible with Enumerations.

Q:

Why do you use the App_Code folder in ASP.NET?

Answer

The App_Code folder is automatically present in the project. It stores the files, such as classes, typed data set, text files, and reports. If this folder is not available in the application, you can add this folder. One of the important features of the App_Code folder is that only one dll is created for the complete folder, irrespective of how many files it contains.

Explain about AngularJS boot process.

Answer

When the page is loaded in the browser, following action takes place:


HTML document is loaded into the browser, and evaluated by the browser. AngularJS JavaScript file is loaded; the angular global object is created. Next, JavaScript which registers controller functions is executed.


AngularJS scans through the HTML to look for AngularJS applications and views. Once view is located, it then connects that view to the corresponding controller function.


Then, AngularJS executes the controller functions. It then renders the views with data from the model populated by the controller. The page is ready.
