Use of <button type="submit"> and <input type="submit">

Submitting a form with button and input type

The form can be submitted to the browser by using button and input tag.
But we need to know which one is better for the form.

Diffrence between the <button type="submit"> and <input type="submit"> is,  Input type can hold only specified text inside the value attribute.
But the <button type="submit"></button> can hold any type of data, can add html content in the button tag, 

The button type is newer than input, so some older browser (eg: IE 6 ) dosn't support this tag.

In almost all modern browser will support button.
