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.
If the protruding tissue of a hernia can be manually pushed back through the defect in the body wall (which usually but not always is in the abdominal wall), then the hernia may be considered to be reducible.This is most commonly possible with umbilical and inguinal hernias, but it is not often reliably accomplished.f the bulging tissue cannot be pushed back into its correct anatomical position, the hernia is considered to be incarcerated. When the tissue of an incarcerated hernia loses its blood supply, it becomes a strangulated hernia. Strangulated hernias can become true medical emergencies.
