Detailed explanation-1: -On some older systems, yes. E.G. on the Commodore 64, the KERNEL rom (the closest thing it has to a modern OS) was on a simple ROM chip. A lot of OS-free systems also use ROM to store their programs, for instance NES cartridges.
Detailed explanation-2: -Kernel: As we can see, it’s right in the middle of the layers. It’s the core of the OS. Hardware: It’s the physical machine, the base of the system. It consists of memory, the processor or the central processing unit (CPU), and input/output (I/O) components such as graphics, storage, and networking.
Detailed explanation-3: -Kernel is in a zipped file and usually resides in /boot folder. When a computer boots and user makes a choice of operating system at boot-loader (such as GRUB), the kernel is loaded from hard disk into RAM and unzipped. It takes control of all system resources.
Detailed explanation-4: -ROM contains the programming that allows a computer to start up or regenerate each time it is turned on. ROM also performs large input/output (I/O) tasks and protects programs or software instructions.
