Flip-flops and latches are used as data storage elements. A flip-flop stores a single bit (binary digit) of data; one of its two states represents a one and the other represents a zero. Such data storage can be used for storage of state, and such a circuit is described as sequential logic.

Scarring is related to age, ethnicity, and the depth and location of the burn. Scars form when the dermal or lower layer of the skin has been damaged. The body forms a protein called collagen to help heal the damaged skin. Normally the collagen fibers are laid down in a very organized manner, but in hypertrophic scars these fibers are created in a very disorganized manner, which gives the new skin/scar a different texture and appearance.
