🧠 A process's memory layout

text · data · bss · heap · stack — what lives where, and why it decides lifetime and cost.

How the OS lays a process into segments — text, rodata, data, bss, heap (grows up) and stack (grows down) — with a runnable that confirms the ordering at runtime, why .bss is free on disk, and how the layout drives lifetime, security and allocation cost.
