What is the arithmetic logic unit?
A)The actual hardware that interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together
B)Interprets software instructions and literally tells the other hardware devices what to do, based on the software instructions
C)A type of CPU that can recognise as many as 100 or more instructions, enough to carry out most computations directly
D)Performs all arithmetic operations (for example, addition and subtraction) and all logic operations (such as sorting and comparing numbers)

Question

Quizplus · Accepted Answer

The arithmetic logic unit (ALU) is responsible for performing all arithmetic and logic operations in a computer's central processing unit (CPU). This includes mathematical computations such as addition, subtraction, multiplication, and division, as well as logical operations such as testing for equality or inequality and comparing values. The ALU is a critical component of the CPU and plays a key role in executing software instructions. Option A is incorrect because the ALU is only one part of the hardware that operates together with other components to run a program. Option B is incorrect because the ALU does not literally tell the other hardware devices what to do, it only performs arithmetic and logic operations. Option C is incorrect because the number of instructions recognised by a CPU is not directly related to the function of the ALU.
