What is a flip flop
A flip-flop is used to store binary data, and is a simple latching circuit.
Basic (SR) Flip Flops
Basic flip flops are created using two NAND gates cross couples as seen in the image.

D and T type flippys
A flip flop has two inputs. One input is a control input. For a D flip flop, the control input is labelled D. For a T flip flop, the control input is labelled T. The other input is a clock input, labelled either with a triangle or CK.
