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.

A scar results from the biological process of wound repair in the skin-a natural part of the body's healing process. Any burn, injury, skin condition, or other trauma, such as surgery, can cause a scar.They form when the dermis (deep, thick layer of skin) is damaged. The body forms new collagen fibres (a naturally occurring protein in the body) to mend the damage, resulting in a scar.The new scar tissue will have a different texture and quality than the surrounding tissue; while most scars are flat and pale, some can be raised, sunken, or pitted in appearance.he body forms new collagen fibres (a naturally occurring protein in the body) to mend the damage, resulting in a scar.
