There are four separate types of diving, of which SCUBA (Self Contained Underwater Breathing Apparatus) is the most recently invented.

We will not look at skydiving and aerial diving or other types of diving here, only the types related to swimming under the water.

Diving can involved holding one's breath (free diving, skin diving). This earliest form of diving is still practiced for both sport and for money (e.g., ama divers of Japan and Korea, pearl divers of the Tuamoto Archipelago). The breath-hold diver's compressible air spaces are squeezed by the raised water pressure throughout the dive. Each dive, limited by the individual's tolerance for breath-hold and the risk of drowning from hypoxia, is usually less than 60 seconds.

Diving with compressed air or other gas mixture that is carried by the diver (scuba diving).
There are two principle types of scuba: open and closed circuit. Open circuit vents all expired air into the water, and is the mode used in recreational diving. Closed circuit systems, in which exhaled air is re-breathed after carbon dioxide is absorbed and oxygen added, were widely used before open circuit became available, particularly by military divers who wished to avoid showing any air bubbles.

Diving in a container with strong walls.
Heavy-walled vessels can maintain their inside atmosphere at or near sea level pressure ('one atmosphere' or 'one atm.'), and so prevent the surrounding water pressure from affecting the occupants. Such vessels include: the bathysphere, an unpowered hollow steel ball lowered from the mother ship by steel cable; the bathyscaphe, a bathysphere with buoyancy control so that cable is not needed for descent and ascent; and the submarine, which can travel great distances in any direction under its own power. A modern extension of the one-atmosphere vessel is the self-contained armored diving suit, flexible yet able to withstand pressures at great depth.

Diving using compressed air supplied above the surface.
The diver is separated from the supply of fresh air, which is kept on the surface. Air reaches the diver through a long umbilical, which in its simplest form ends in a regulator and mouthpiece carried by the diver. Devices in this category include caissons (huge spaces supplied with compressed air, employed mainly for bridge and tunnel work), diving bells, and rigid-helmet diving suits. In all these devices the diver breathes air at the same pressure as the surrounding water pressure, and so is at risk for decompression problems (bends, air embolism, etc.) if ascent is too fast.
