Static vs Dynamic library in Linux, PIC, PIE, plt, got, Virtual vs Physical Addresses:

---

plt ---> procedure linkage table

got ---> global offset table

logical addresses ---> virtual addresses

virtual address space (VAS) or address space ---> is the set of ranges of virtual addresses that an operating system makes available to a process.

memory management unit (MMU) or paged memory management unit (PMMU) ---> is a computer hardware unit having all memory references passed through itself, primarily performing the translation of virtual memory addresses to physical addresses.

Virtual address space randomization ----> Address space layout randomization ----> (ASLR)

ELF

ELF Header

The first portion of any ELF file is the ELF header. This generally provides offsets to other headers (program headers and section headers) within an ELF.

typedef struct {
  unsigned char e_ident[EI_NIDENT];
 uint16_t e_type;
