Final answer:
The error caused by trying to represent a number that is too large for the system to handle is known as an Overflow error.
Step-by-step explanation:
The term for the error resulting from attempting to represent a number that is too large is a) Overflow error. This error occurs when a computer or calculator tries to handle a number that exceeds its maximum representable value. In contrast, an Underflow error happens when a number is too small to be represented, a Round-off error occurs when a number cannot be represented with the available precision, and a Precision error is related to limits in the precision of calculations or measurements.
