Which of the following is a primary role of the ALU?

• A. Storing data for long-term access
• B. Executing arithmetic and logic operations
• C. Providing network connectivity
• D. Managing peripheral devices

Answer: (B)

The primary role of the Arithmetic Logic Unit (ALU) is to execute arithmetic and logic operations. This includes performing calculations such as addition, subtraction, multiplication, and division, as well as logical operations like AND, OR, NOT, and comparison operations. The ALU is a critical component of the CPU, enabling it to perform the mathematical computations and decision-making processes that are essential for executing instructions in computer programs. The capability of the ALU to handle both arithmetic and logical functions allows the processor to manipulate data and perform a wide range of tasks necessary for complex computations and operations within a computer system. This functionality is fundamental to many applications, from simple calculations to complex algorithms. Other options, such as storing data for long-term access, providing network connectivity, or managing peripheral devices, refer to different roles of computer architecture. For instance, data storage is typically managed by memory units, such as hard drives or SSDs; network connectivity is facilitated through networking hardware; and peripheral devices are managed by the I/O controllers. These roles are distinct from the computational functions of the ALU, highlighting why executing arithmetic and logic operations is the correct and relevant answer in this context.
