I'm wondering how are complete OS made
Which language(s) are used??

All posts welcome

Thanx
 
You can write an OS in many languages. C, C++ and Assembler or Machine
Language are some common ones.
 
Machine Language = Would that mean writing the OS in binary. I mean how is the first interaction between hardware and software made.

It's actually (I believe) an interesting process. Probably somewhat easier
to follow in an old 8-bit computer like an Apple ][ but I'm sure the basics
are the same. I'm quite certain it all starts when the CPU runs it's power
on sequence but you probably want to start with the BOOT ROM. It contains
just enough instructions to get the disk drive to spin and to read a couple
of tracks so more of the OS can be loaded.

Search Google for "bootstrap a computer" and related words. It's quite
clever to go from "lump of metal and silicon" to "operating computer" in
under a minute.
