Take a look at the circuit shown. You use a C-MOS 4013 with preprogrammed D Flip-Flops.
With the inputs SET and RESET you switch, regardless of the clock signal, Clk the result Q...

The input D however has only in conjunction with the clock signal Clk influence on the result Q. Therefore, the input is referred to as synchronous.
In the next experiment you take a look at a JK latch...
