half-adder

[¦haf ¦ad·ər] (electronics) A logic element which operates on two binary digits (but no carry digits) from a preceding stage, producing as output a sum digit and a carry digit.

half-adder

An elementary electronic circuit in the arithmetic logic unit (ALU) that adds one bit to another. The output is the result bit and the carry bit. Just like 9 + 1 derives 0 with a carry of 1, in binary, 1 + 1 yields the same results. See binary and ALU.
