Assembly

All about the assembly language.
First of all, the program must be written in a simple text file, the name of this file is called the source file and its extension has to be .asm.

Example: mySourceFile.asm

There are several assemblers. For example the GNU assembler, named as.
There are also several disassemblers such as the GNU one named objdump.
Note that a disassembler is not a decompiler.
