What is an overflow error in binary addition?

• When the sum of two binary numbers is negative.

• When the result of an addition has more bits than the system can represent.

• When a binary number contains an invalid digit (not 0 or 1).

• When the sum of two binary numbers is zero.

What is a potential consequence if a system discards an extra bit resulting from an overflow error during binary addition?

• The system will crash immediately.

• The calculation will take longer to complete.

• There will be a loss of accuracy in the result.

• The system will automatically switch to a larger bit representation.
