A full-adder adds _____ bits, and producing a SUM and a _____ A. 8, SUBTRACTION B. 3, CARRY C. 16, DIVIDE D. All of the above E. None of the above

8, SUBTRACTION
3, CARRY
16, DIVIDE
All of the above E. None of the above

The correct answer is: B. 3, CARRY

A full adder is a digital logic gate that performs addition on two binary numbers. It has three inputs: two binary numbers and a carry bit. It produces two outputs: a sum bit and a carry bit.

The sum bit is the result of adding the two binary numbers. The carry bit is a 1 if the sum of the two binary numbers is greater than 1.

A full adder can be used to add any number of binary numbers. It is a basic building block of many digital circuits, such as adders, subtractors, and multipliers.

The other options are incorrect because:

  • A full adder does not add 8 bits. It adds 3 bits.
  • A full adder does not perform subtraction. It performs addition.
  • A full adder does not divide. It performs addition.
