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.

Over time, hernias tend to get bigger as the muscle wall of the belly gets weaker and more tissue bulges through. In some cases small, painless hernias never need repair.here are two types of hernia repair surgeries: 1  Open hernia repair surgery. 2  The hernia is repaired through a cut (incision) in the groin. 3  Open surgery is safe and effective and has been done for many years. 4  Laparoscopic hernia repair. 5  This is another method for hernia repair in adults.
