What is an overflow error in numeric representations?
It occurs when a program has too many syntax errors.
It happens when a program's runtime exceeds a certain limit.
It's a logic error that causes incorrect results due to a wrong algorithm.
It occurs when a calculation results in a value that's too large to be stored within a given data type.
Why do we use hexadecimal representations for digital data in computing?
Hexadecimal is the most efficient representation for all types of data.
Hexadecimal is the native format used by modern computer hardware.
Hexadecimal provides a compact way to represent large binary values.
Hexadecimal ensures compatibility with non-digital devices.
