Which of the following statement(s) is/are correct? Statement A : ALU can perform both arithmetic and logical operations. Statement B : CPU is used to process, display and store data or information.

Key Points

• The Arithmetic Logic Unit (ALU) is a digital circuit within the CPU that performs arithmetic and logical operations.
• ALU is a fundamental building block of the CPU in computers.
• Statement A is correct because the ALU can perform both arithmetic (e.g., addition, subtraction) and logical operations (e.g., AND, OR, NOT).
• Statement B is incorrect because the CPU is primarily responsible for processing data, while display and storage tasks are handled by other components like the GPU (Graphics Processing Unit) for display and storage devices (e.g., SSDs, HDDs) for storage.

Additional Information

• Arithmetic Logic Unit (ALU)
  • The ALU is a crucial component of the CPU in a computer system that handles both arithmetic operations like addition, subtraction, multiplication, and division, and logical operations such as comparisons (AND, OR, NOT).
  • It takes in binary data as inputs and performs the required operations, outputting the result for further processing or storage.
• Central Processing Unit (CPU)
  • The CPU is often referred to as the brain of the computer, where most calculations take place.
  • It consists of the ALU, Control Unit (CU), and various registers for temporary storage of data and instructions.
  • While the CPU is responsible for processing instructions and data, other components like the GPU handle display tasks, and storage devices like SSDs and HDDs are used for storing data.
• Graphics Processing Unit (GPU)
  • The GPU is specialized for rendering images and videos and is used primarily for display purposes, particularly in tasks involving complex graphics and visual computations.
• Storage Devices
  • Storage devices such as Solid State Drives (SSDs) and Hard Disk Drives (HDDs) are used to store data and information persistently.
  • These devices retain data even when the computer is turned off, unlike the temporary storage provided by the CPU registers and RAM.
