- **Null** - These sections can be ignored
- **Program Data** - These link to segments, if I remember right
- **Symbol Table** - Here are all the executables' symbols stored
- **String Table** - Here are all strings stored
- **RelocationA** - Contains relocation information
- **Hash** - Symbol Table hash table
- **Dynamic Link** - This provides information for the dynamic linker
- **Note** - notes that were created by the compiler / toolchain
- **Nobits** - Nulled data like `.bss`
