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.
There is a small chance it might strangulate. A hernia strangulates when too much bowel (intestine) comes through the gap in the muscle or ligament and then it becomes squeezed. This can cut off the blood supply to the portion of intestine in the hernia. This can lead to severe pain and some damage to the part of the intestines in the hernia.
