Answer 1

placeholder and name are different attributes. An input with a type such as search, password, text e.t.c can have the placeholder attribute which will provide a hint within the textbox with whatever value the placeholder is set to. Input elements can also have a name attribute which can act to reference that element. Since they are different they can also have both attributes.
