Any construction forming enclosed 'rooms' above the hull is the superstructure. There are many types of deck, named generally for their function. The Boat Deck is the deck where the lifeboats are stored. The Bridge deck is where the helm and navigation station are (among other things). These are all above the waterline.

On a cargo ship or tanker, the raised structure at the rear would be referred to with the general term 'superstructure' and the raised structure at the front would be called the 'forecastle'. The part in the middle is the 'weather deck'. Passenger ships and modern military craft that are more block-like or pyramid shaped have more names for their decks, usually labeled by function.
In older designs for sailing vessels, ships had a raised deck in the fore and aft parts of the ship to provide elevated fighting positions for archers, and later for rifleman. The part in the front was called the forecastle (aka fo'c'cle, fo'c's'le). This section commonly housed the sailor's quarters. It is one of the most uncomfortable places to sleep while underway due to pitching of the vessel.
Similarly there was the Aftcastle in the aft (rear) part of the boat. You'll often hear the term "Poop Deck" for the raised deck aft (from the french" la poupe" for stern). In addition to benefits as an elevated fighting position, it provided good visibility of the sails, decks, and for navigation.
