Why do we need to use <header> tag if we have <h1>, <h2>, ...?

Question

Before, I found that I can add headings using these tags: <h1>, <h2>, <h3>, <h4>, <h5>, <h6>. But now I came across the <header> tag to add headings. But why do we have another tag to add headings if we already have <h1>, <h2>, <h3>,...?

Answer 1

<header> tag is not for headings. It is used to create the top panel where logo, navigation, etc. are located.
