So what does plain binary mean? 

Quoted from Nasm Documentation

6.1 bin: Flat-Form Binary Output
The bin format does not produce object files: it generates nothing in the output file except the code you wrote. Such `pure binary' files are used by MS-DOS: .COM executables and .SYS device drivers are pure binary files. Pure binary output is also useful for operating system and boot loader development.

OK, if we wanna to generate a plain binary file , we can do the following:

With nasm,as if you don't -f option , it'll chose bin as its default output format!
    nasm hello.asm -o hello.bin

With gcc , you can
    gcc -c hello.c
    ld -o hello -Ttext 0x0 -e main hello.o
    objcopy -R .note -R .comment -S -O binary hello hello.bin

Plain Binary=Flat-Form Binary=Raw Binary, but not 100% sure about this : )
