16. The purpose of the Arithmetic Logic Unit within the Central Processing Unit is to

act as a temporary store for information being processed

perform calculations in the binary, octal or hexadecimal system

perform calculations in the binary number system

perform all clock functions based on the computer clock frequency (clock time)

17. The two types of binary logic are

positive and reversible

variable and reversible
