Correct Answer: Excess 3-Code


Solution : The correct answer is Excess 3-Code.

The excess-3 code is not weighted. A weighted code is one in which each digit has a defined weight and the code's value is the sum of the weights of the digits. The excess-3 code is a non-weighted code, which means that the digits do not have defined weights. Excess-3 code was used on some earlier computers, in addition to cash registers and transportable digital calculators.
