I post the Answers for the above questions.

2) what is GAC?
A) Global Assembly Cache, When we need to share the assembly to all then we copied that assembly into GAC Floder but that must be having name, version and public key token. Which are the assemblies follows all those 3 then we install that assembly into GAC folder before that we must create key.snk file for that.
Once the Assembly is in shared location then any one can access that assembly in to there application.
6.what is Assembly and types?
An assembly is a collection of types and resources that forms a logical unit of functionality.

When you compile an application, the MSIL code created is stored in an assembly .
Assemblies include both executable application files that you can run directly from Windows without the need for any other programs (these have a .exe file extension), and libraries (which have a .dll extension) for use by other applications.
There are 3 types of assemblies
• Private Assembly
When the Assembly doesn't copied in GAC folder then we must added that in our physical location that means our project bin folder this type of assembly we are called as Private Assembly, it is very secure compare to shared Assembly.

• Shared Assembly
When the Assembly is registered in GAC folder that means which assembly having name, version and public key token then we store them in GAC folder, that Assemblies we are called as Shared Assembly.

• Satellite Assembly
When we go for multilingual application implementation then we go for Satellite assembly.
7.what is CLR?
CommonLanguageRuntime ( CLR) to convert the managed code into native code and then execute the program.

1.what is state management?
A) Web is stateless because of HTTP, to maintain the state for controls ASP.net introduces a concept called as State Management.
2what is session ?
A) When new user makes a request then session object will create. Session will store any type of data.

3.what are session different mode?
A) inproc, sqlserver, and stateserver
4.what is InProc and where value will be store?
A) It will store it in the worker process in the application domain.
5.what is view state and where the values are save and what happen if more value save?
A) View State is the technique used by ASP.NET web pages to keep the state of the page across post backs. It stores data in a hidden field named __VIEWSTATE inside the page in Base-64 encoded formats. The encoding and decoding of the view state data is done by the LosFormatter class.


There is a provision of turning off ViewState at control level and also at page level using the property EnableViewState.

View State data will store in client side.

7.how u valid the page?
A) We can validate a page in 2 ways either client side or in server side.

8.whether client side validation or server side validation? which one is best?
A) mostly in client side, Client side is the best option to validate it. Why because it's reduces the post backs.
2.what is type - casting?
A) It converts one type of data in to another type.
4.what is encapsulation?
A) Encapsulation is the mechanism to hide irrelevant data to the user.
5.what is polymorphism?
A) Using the same method in multiple forms is called as Polymorphism. In the Polymorphism, the method name is same but their prototype can be different.
7.what is abstract class?
A) Abstraction is the mechanism to show only relevant data to the user.
8.what is virtual function and where it will be use code level?
A) To override base class information into derived then we go for virtual classes.
9.what is sealed class what sincero use?
A) To prevent override data from base class to derived for that purpose we used Sealed class. By default all classes are sealed only but using virtual/ Abstract the behavior is get changed.
1.write the query for top 2nd ?
Select Top(2) * from tablename
4.can you insert/delete in view and its reflect in the table?
Yes, we can perform All CRUD operations using View it's get reflected in a table also.
5.what are joins available?
In SQL we have different types of joins are available.
Inner Join, Outer Join, Join, Left Outer join, Right Outer Join, Self Join, Cross Join.
7.what is index and explain?
To get the table data without delay for that purpose we go for indexes. There are 2 types
1) Clustered Index
2) Non-Clustered Index.
8.what is default non-cluster index value in 2005 and 2008?
In SQL 2005 – 249
