Which file formats are supported by NASM?

NASM can output several binary formats, including COFF, OMF, a. out, Executable and Linkable Format (ELF), Mach-O and binary file (. bin, binary disk image, used to compile operating systems), though position-independent code is supported only for ELF object files. NASM also has its own binary format called RDOFF.

What is DB in NASM?

db does not have any magic effects: it simply outputs bytes directly to the output object file. If those bytes happen to be in front of a symbol, the symbol will point to that value when the program starts. If you are on the text section, your bytes will get executed. Weather you use db or dw , etc.
