Definitely we're beyond "medium memory model" and stuff like that programming for 16-bit computers. Although even in 64-bit there is separation of code and data somehow, but not as restrictive as it was with 16-bit. It's more like it was in 8-bit, the only difference is that 8-bit had to hold everything in 64KB. On MS-DOS and predecessors COM-suffix files for 8-bit instead of EXE files which were necessary to move up to Windows. I don't know if GNU/Linux had to make a similar progression.
