A deck refers to one of several levels of a vessel or starship or similar vessel, comparable to floors of a building. The deck itself was typically made of deck plating. (ENT: "Fight or Flight")

An order to "hit the deck" was an Earth nautical term meaning to drop to deck plate. (Star Trek IV: The Voyage Home)

Aboard Earth starships in the 21st and 22nd centuries, decks were named alphabetically; A-deck would be on top, B-deck right below it, etc. This naming scheme was used as early as 2069, aboard the SS Conestoga. (ENT: "Terra Nova", "The Catwalk")

By the 23rd century, Federation starships had adopted a system where the upper level was referred to as deck 1. Deck numbers then increased for each deck below, the lowest level having the highest number. For example, the Intrepid-class USS Voyager's lowest deck was deck 15. (VOY: "Good Shepherd")

However, aboard the Constitution II-class USS Enterprise, the decks were ordered alphabetically again rather than numerically. The bridge was located on Deck A (as indicated by signage on the turbolift doors). Following an attack by Khan Noonien Singh in 2285, the turbolifts aboard the Enterprise were rendered inoperative below C-Deck. (Star Trek II: The Wrath of Khan)
