👉 The CPU (Central Processing Unit) manages and coordinates the execution of instructions in a computer system, including those that handle light particles in applications like graphics processing units (GPUs) or scientific simulations. In the context of light particles, the CPU's role involves directing the flow of data and control signals to render and manipulate these particles, which are often used to simulate lighting effects, reflections, or atmospheric phenomena. The CPU works in tandem with specialized hardware, such as GPU cores optimized for particle rendering, to efficiently process and display light particles, ensuring smooth and realistic visual outputs in real-time applications like video games or scientific visualizations.
