What Happens When
This project is a collaborative knowledge base and technical learning resource that provides a detailed breakdown of the internal processes occurring within modern computing environments. It serves as a comprehensive educational reference, tracing the step-by-step operations triggered by common user interactions and network requests to explain how hardware and software components interact across the entire stack.
The guide distinguishes itself by offering deep technical insights into the journey from physical input to visual output. It covers the low-level mechanics of hardware interrupt handling and operating system event dispatching, alongside the complex stages of the browser rendering pipeline and network protocol analysis. By examining these systems in tandem, the repository illustrates how raw data is transformed into a functional graphical interface.
The documentation explores a wide range of system internals, including URL processing logic, DNS resolution, and secure communication handshakes. It provides structured explanations for various stages of web architecture, such as markup parsing, style interpretation, and GPU-accelerated rendering, offering a granular view of the operations that occur under the hood during standard web browsing.
