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.
1 Incisional hernia can occur through a scar if you have had abdominal surgery in the past. 2  Umbilical hernia is a bulge around the belly button. 3  It occurs when the muscle around the belly button does not close completely after birth.
A hernia occurs when an organ pushes through an opening in the muscle or tissue that holds it in place. For example, the intestines may break through a weakened area in the abdominal wall. Hernias are most common in the abdomen, but they can also appear in the upper thigh, belly button, and groin areas. Most hernias are not immediately life threatening, but they donât go away on their own and can require surgery to prevent potentially dangerous complications.
