What "harness" means in rock climbing

In rock climbing, a harness is a piece of equipment that is worn around the waist and thighs, and it is used to attach the climber to a rope. The rope is usually fixed to the harness using a figure 8 knot, and the climber ascends the climb while being belayed by a partner who controls the rope. The harness redistributes the weight of the climber across the waist and thighs, which helps to prevent injury.
