Something that adds numbers using digital logic. It's works by connecting the carrys from four full adders to create a 4 bit ripple adder. The carry ripples down the adders, which is why it's called a ripple adder.
Generally considered a slow design. Look into Carry Look Ahead adders if you want something faster.

A binary full adder has two inputs and two outputs. The inputs are the number to add, and the 'carry' input. The outputs are the result, and the carry output. you connect the carry of one to the carry of the next, and you have a 2-bit adder, connect two of those you have a 4-bit, then 8, then 16, then 32, then 64...

You should be able to find the circuit for that in any good book on combinational logic circuits. It is a basic element of microprocessors.
