Every Question..What does it mean? Why is this? How it works?
Microsoft .Net (pronounced dot (.) net) may be a package element that runs on the Windows software package.
.Net provides tools and libraries that change developers to form Windows package a lot of quicker and easier.
Microsoft describes it as:".Net is that the Microsoft internet Service strategy to attach data, people,
system and devices through software".I'm Choulla Naresh..!

Difference Between "string" and "String"
what is
the difference between both (String and string)?
After completing the execution of this program when we mouse over on string is shows class
System.String and when we mouse over on String it also shows Class
System.String. Class System.String statement clarifying that string is the alias name of String.
Finally:
Finally:
String is the alias name of String because both contain the same things

Difference between TextBox and TextBoxFor:
@Html.TextBox() is loosely typed method whereas @Html.TextBoxFor() is a strongly typed (generic) extension method.
TextBox() requires property name as string parameter where as TextBoxFor() requires lambda expression as a parameter.
TextBox doesn't give you compile time error if you have specified wrong property name. It will throw run time exception.
TextBoxFor is generic method so it will give you compile time error if you have specified wrong property name or property name changes. (Provided view is not compile at run time. )

SQL Server Languages – DML, DDL, DCL & TCL
There are mainly 4
types of language statements or commands in SQL Server.
DML
DML is abbreviation of Data
Manipulation Language. It is used to retrieve, modify, add, and delete data
in database.
Examples: SELECT,
UPDATE, INSERT, DELETE statements
1.
SELECT – used for retrieving data from the
database.
2.
UPDATE – used for modifying the data in the
database.
3.
INSERT – used for adding or inserting new data
into database.
4.
DELETE – used for deleting the already existing
data from database.
DDL
DDL is abbreviation of Data
Definition Language. It is used to create, modify and destroy the structure
of database objects in database.
Examples: CREATE,
ALTER, DROP, TRUNCATE statements
1.
CREATE – used for create database objects like
tables, stored procedures, functions etc.
2.
ALTER – used for modifying the existing
database objects like tables, stored procedures, functions etc.
3.
DROP – used to drop or deleted the existing
database objects.
4.
TRUNCATE – used to delete all the
records from table and to reset identity of column to
initial value.
DCL
DCL is abbreviation of Data
Control Language. It is used to create roles, permissions, and referential
integrity as well it is used to control access to database by securing it.
Examples: GRANT,
REVOKE statements
1.
GRANT – used for creating access
permissions for users to database.
2.
REVOKE – used for revoking the already assigned
permissions.
TCL
TCL is abbreviation of Transactional
Control Language. It is used to manage different transactions occurring
within a database.
Examples: COMMIT,
ROLLBACK, SAVE TRANSACTION statements
1.
COMMIT – used for saving the work done in a
particular transaction. For example: “Ctrl + S” in word file.
2.
ROLLBACK – used for reverting the transaction to
the original state before commit. For example: “Ctrl + Z” in word file.

Difference between == and === with Example-JavaScript
This is one of the most frequently asked question in interview when one tries to judge your jQuery orJavaScript concepts.
JavaScript provides different types of operators. Here, we will be talking about strict equality andType converting equality.
Strict equality (===) means values which we are comparing must have the same type. This means "2" will not be equal to 2 ("2"===2 it will return false)
Type converting equality (==) means automatically it will covert variable to value irrespective of data type, either it is string or number. This means "2" will be equal to 2 ("2" == 2 it will return true)
So the double equal (==) is an auto type converting equality and three equal (===) is strict equality operator i.e it will not covert values automatically.
Demo 1
1==”1″ // it will return true because here string will converted as number
1 === “1” // it will return false because here 1 is number and “1” is string
1 === “1” // it will return false because here 1 is number and “1” is string
Demo 2
0 == false // it will return true because here false is equivalent of 0
0 === false // it will return false because both are different operands
0 === false // it will return false because both are different operands
I have included the complete example for you to check the result yourself as shown below:
<!DOCTYPE HTML> <html> <head> <title>Jquery - Difference between == and ===</title> <script type="text/javascript"> function CheckDifference() { var val = "2"; document.write("Value for a variable is : " +val +"<br/>"); if (val == 2) document.write("== returns True <br/>") else document.write("== returns False <br/>") if (val === 2) document.write("=== returns True <br/>") else document.write("=== returns False <br/>") } </script> </head> <body> <h2>JQuery or JavaScript - Difference between == and ===</h2> <hr/> <br/> <div id="div1"> <input type="button" id="Check" onclick="CheckDifference()" value="Click to Check Difference" /> </div> </body> </html>
Difference between a library and a framework?
Library
A library is a reusable piece of code which you use as it comes i.e it does not provide any hooks for you to extend it.
Framework
A framework is a piece of code which dictates the architecture your project will follow.

·
A
framework is a piece of code which dictates the architecture your project
will follow.
|
·
A
library will usually focus on a single piece of functionality, which you
access through an API.
|
·
Once
you choose a framework to work with, you have to follow the framework’s code
and design methodologies.
|
·
You
call a library function, it executes some code and then control is returned
to your code.
|
·
The
framework will provide you with hooks and callbacks, so that you build on it.
|
·
Library
doesn’t contain framework.
|
·
A
framework will usually include a lot of libraries to make your work easier

SilverLight
Silverlight is a powerful cross-browser & cross-platform technology for building the next generation web experience & rich internet applications for the web.
Silverlight applications are delivered to a browser in a text-based markup language called XAML. XAML is a declarative markup language that you can use to define the UI elements for your Silverlight-based application.
Silverlight is considered as a competitor to Adobe's flash technology.
One of the design goals of the Silverlight technology is to fill the gap between windows application and web application in terms of creating Graphical User Interface (GUI). So far web developers were not able to make client happy in terms of UI, but now web developer will be able to full fill this with the help of Silverlight technology.
You can run Silverlight in most of all the popular browsers like Internet Explorer, Firefox, Chrome, Safari etc. Silverlight can run in various devices and operating systems like Windows, Apple Mac OS-X and Windows Phone 7.
Using Silverlight you can create rich, visually stunning web applications like flash. Also you can create smooth animations using Storyboards; you can stream media over the net etc.
Silverlight web browser plug-in comes as free to install (approximately 4-5 MB in size). You can download the required plug-in from Microsoft Silverlight Site.
