Follow the life of a Linux command from request, through process creation, memory management, address translation, caching, and diagnostics.
The Event Map remains open. Section links reuse one reading window. Diagram links reuse one diagram window.
A command begins at a shell, terminal, script, service manager, or other request path.
Linux receives a service-oriented request and routes it through systemd/systemctl behavior.
Linux creates a process, then the requested program image is loaded into that process.
The running program has text, data, heap, stack, libraries, and mapped memory regions.
When memory is referenced but not immediately available, the kernel resolves the fault.
Virtual addresses are translated to physical addresses using page tables and the TLB.
The CPU searches for instructions and data through cache layers before reaching main memory.
