Answer 1

The correct answer is Graphic Card.

Key Points

The Central Processing Unit (CPU) primarily consists of three main components: Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers. These work together to process data and execute instructions.
A Graphic Card is a separate hardware component designed to handle the rendering of images, videos, and 3D graphics, and is not a part of the CPU.
The Arithmetic Logic Unit (ALU) is responsible for performing arithmetic and logical operations within the CPU.
The Control Unit (CU) directs the flow of data within the CPU, coordinating the activities of other components.
Registers are small storage locations within the CPU that hold data, instructions, and addresses temporarily during computation.

Additional Information

Central Processing Unit (CPU): Often referred to as the "brain" of the computer, the CPU performs all processing tasks and executes instructions from programs.
Graphic Card: Also known as a GPU (Graphics Processing Unit), it is optimized for rendering images and videos. It is essential for tasks such as gaming, video editing, and 3D modeling, but operates independently of the CPU.
Registers: These are high-speed storage units located inside the CPU. Examples include the accumulator, instruction register, and program counter.
Control Unit (CU): The CU interprets instructions from programs and directs the operation of the CPU and other components such as memory and I/O devices.
ALU (Arithmetic Logic Unit): Performs mathematical calculations (addition, subtraction, multiplication, division) and logical operations (AND, OR, NOT) within the CPU.
