Osmosis specifically refers to the movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration until equilibrium is reached. This process does not involve the movement of salts across the membrane, but rather the movement of water towards the area of higher salt concentration.
