Central Processing Unit

The Central Processing Unit (CPU)

The Central Processing Unit (CPU) is the brain of your computer. It executes the instructions of a program efficiently. The CPU handles basic arithmetic, logical, control, and input/output (I/O) operations to ensure smooth performance.

How the CPU Works

• Fetching Instructions: The CPU retrieves instructions directly from the computer’s memory.
• Decoding Instructions: It translates these instructions into understandable operations for execution.
• Executing Instructions: The CPU promptly performs the actions specified by the decoded instructions.

Key Components of a CPU

• Arithmetic Logic Unit (ALU): Executes arithmetic and logical operations, ensuring precise calculations and decisions.
• Control Unit (CU): Coordinates CPU operations, including fetching and decoding instructions for proper task execution.
• Registers: Offers small, high-speed storage to hold data and instructions during processing.
