Question

TEZPUR 2025 — Computer PYQ

TEZPUR | Computer | 2025

Which of the following modules performs the arithmetic operations in a computer?

Choose the correct answer:

Explanation

In the architecture of a computer's Central Processing Unit (CPU), specific components are responsible for different tasks. The component dedicated to mathematical calculations is the ALU (Arithmetic Logic Unit).

ALU (Arithmetic Logic Unit): This is the part of the CPU that performs arithmetic operations (addition, subtraction, etc.) and logical operations (AND, OR, NOT, etc.).
CMU: Not a standard term for a primary CPU module (often associated with Control Management Unit, but not the standard answer here).
RAM (Random Access Memory): Used for short-term data storage, not for performing calculations.
Accumulator: A type of register inside the CPU that stores the intermediate results of arithmetic and logic operations; it does not perform the operation itself.

If we let $C$ be the set of CPU components and $O$ be the operation of performing arithmetic, we can define the relationship as:

$A LU \in C ⟹ P er f or m s (A LU, O) = T r u e$

$R A M \in C ⟹ P er f or m s (R A M, O) = F a l se$
