Program sections, or what are
When a program is compiled, the compiler splits the resulting code into different sections (sometimes called segments). Every section corresponds to a particular use, for instance storing variables or executable code.
This document is mainly focused on the ELF (Executable and Linkable Format) file format used
by Linux and the
gcc<code> toolchain, but most of this document is valid for most executable file formats.
|.text||Executable (machine) code|
|.bss||Data initialized to zero|
