Read about the "definition" in those links, which Samba had given you. If you still have trouble, there is a "Try it yourself" button, which can be used to test it. Play with it by changing the name and value.

I tried akhileshbc, but still not clear to me, that where exactly we need to use?

Name is the attribute to identify that particular element.
And value is the attribute to display a value inside it.

In your example,

Code:

---

<input type = "text" name = "Username" value = "VBFORUMS">

---

the above code will display a text box and it's name is "Username" and inside it, it will display "VBFORUMS".

When you submit a form to a serverside page(eg: PHP, JSP, ASP, etc..), the submitted data would contain the "name" and "value". So, if you want to access the value entered by user in the textbox for "Username", you can use the name attribute to access it.

In PHP, an example would look like this:

PHP Code:

---

$username = $_POST['Username'];

// Above code is for forms submitted via POST method and below is for GET method

$username = $_GET['Username']; 


---

So, when you use it like above, the variable "$username" will hold the value entered by the user(eg: "VBFORUMS")

That is the case of server side!
In client side also, this is useful. Say, if you want to validate the username entered by an user. So, via JavaScript, you could access the textbox named "Username" and get its value and check it.

Consider this simple example: in a class there are several students. If those students don't have a name, teacher can't call them and ask them questions(this is an example, so don't ask me whether the teacher could point out some one and ask questions :p)
So, if teacher knows his students names, he could easily call them and ask questions.

So, consider the name of the student as the "Name" attribute and the answer from the student as the "Value" attribute. :)

I hope you understand the idea. :)
