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.

Risk of strangulation: In considering when to have a reducible hernia operated on, it is important to know the risk of strangulation. The risk varies with the location and size of the hernia and the length of time it has been present. Inguinal hernias, the most common type of hernia, have been the most intensively studied. For direct and indirect inguinal hernias, the risk of strangulation is 2.8% for the first three months, increasing to 4.5% over two years. Femoral hernias, although rare, are especially prone to strangulation.
