...Rather than giving a high-level overview, the repository tries to break down every step in the process, from low-level events (keyboard press, OS events, keyboard interrupts), through OS-level handling (keyboard scan codes, key events), parsing, DNS lookup, networking (ARP, socket creation, TCP/TLS handshake), HTTP requests, browser behavior, HTML/CSS/JS parsing, rendering engine, GPU rendering, layout, to final drawing and user-visible output. The goal is to serve as a comprehensive resource for students and engineers to understand what happens under the hood, bridging from hardware and OS level up through network and application layers.
