Would you consider a firmware something similar to an Os, and what are the main differences between the two?

No, I wouldn't consider these the same. Fireware is embeded into hardware whereas an OS interacts with the fireware/hardware and displays the results to the user. Fireware can be flashed and is stored in ROM. The OS is stored on the hard drive and can be modified at any time.

So are you saying that the firmware is more low level than the OS, when it comes to communicate with hardware?

yes
I'm an angel. I kill firstborns while their mamas watch. I turn cities into salt. I even, when I feel like it, rip the souls from little girls, and from now till kingdom come, the only thing you can count on in your existence is never understanding why.

Do you know how you got that dent, in your top lip? Way back, before you were born, I told you a secret, then I put my finger there and I said "Shhhhh!"

What about RTOS (Real Time Operating Systems)?
Size does matter for science and its laws changes accordingly.

The Crazy One
A RTOS is usually used for safety-critical applications - eg, your car brakes. Its not very suitable for common use because even the best scheduler will usually only get 70% efficiency, max, from a cpu. Firmware can be designed into a chip via logic, or it can be stored on a rom, which can be software updated, or flashed with an infrared light.
