Question

Answer

An arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU - for example, one for fixed-point operations and another for floating-point operations. (In personal computers floating point operations are sometimes done by a floating point unit on a separate chip called a numeric coprocessor.)An arithmetic logic unit is also known as an integer unit (IU).

Answer

The correct answer is option (C) Arithmetic logical unit (ALU)
Explanation: A computer’s core part is ALU. This can execute logical and arithmetical operations on specific data provided by the user. It can compute a function on the two inputs and offer an accurate result or output.

Here, the arithmetic operation comprises of addition, subtraction, division, and multiplication whereas the logical operations check whether the two conditions are true or false. Therefore, hardware which could add up two values is termed as ALU.

Answer

Arithmetic Logic Unit (ALU)
The correct answer is option 'C', which is the Arithmetic Logic Unit (ALU). The ALU is a fundamental component of a computer's central processing unit (CPU) that performs arithmetic and logic operations on input data.

Explanation:

What is an ALU?
An Arithmetic Logic Unit (ALU) is a digital circuit within a CPU that performs arithmetic and logical operations such as addition, subtraction, AND, OR, etc.

Function of ALU:
- The primary function of the ALU is to perform arithmetic and logical operations on data that is being processed by the CPU.
- It receives input data from memory or registers, performs the necessary calculations, and outputs the result.

Adding two numbers:
- In order to add two numbers, the ALU takes the two numbers as input, performs the addition operation, and produces the sum as the output.
- This process is carried out by the ALU's arithmetic circuits, which are designed to handle simple operations like addition, subtraction, multiplication, and division.

Conclusion:
In summary, the Arithmetic Logic Unit (ALU) is the hardware component responsible for performing arithmetic operations such as adding two numbers. It is an essential part of the CPU and plays a crucial role in the overall processing of data in a computer system.
