Alogic circuit, that can add two 1-bit numbers and produce output for sum and carry but cannot handle carry, input, is called \( \qquad \) .
A half adder adds two 1-bit inputs and gives two outputs: Sum = \(A \oplus B\) and Carry = \(AB\). It has no input for a carry coming from a previous stage.
A full adder has three inputs (A, B and carry-in), so it can handle an input carry.
Answer: (A) Half adder
