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.
