Which part of the computer is responsible for logical operations?

The correct answer is ALU.

Key Points

• The Arithmetic Logic Unit (ALU) is a fundamental component of the CPU responsible for performing arithmetic and logical operations.
• It handles basic operations like addition, subtraction, multiplication, division, and comparison operations (e.g., greater than, less than, equal to).
• The ALU processes logical operations such as AND, OR, NOT, XOR, which are critical for decision-making in computation.
• It works in conjunction with the Control Unit and memory to execute instructions and manage data flow.
• The ALU is a core building block of modern processors, crucial for both simple and complex computational tasks.

Additional Information

• Control Unit (CU):
  • The Control Unit is another component of the CPU that directs the flow of data between the CPU, memory, and input/output devices.
  • It decodes instructions from programs and signals the ALU and memory to execute operations.
• RAM (Random Access Memory):
  • RAM is a type of volatile memory used to store data temporarily while a computer is running.
  • It does not perform logical operations but serves as a workspace for the CPU.
• Hard Disk:
  • A hard disk is a non-volatile storage device used to store data permanently, including the operating system, applications, and files.
  • It plays no role in logical or arithmetic computations.
• Registers:
  • Registers are small, high-speed storage locations within the CPU used to temporarily hold data during computation.
  • They work closely with the ALU to perform operations efficiently.
