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.
Repairing the hernia can also relieve the symptoms of pain and discomfort and make the bulge go away. The hernia won't heal on its own. If your hernia does not bother you, most likely you can wait to have surgery. Your hernia may get worse, but it may not.
