Detailed explanation-1: -Besides the ROM image, a ROM also contains other parts such as the graphical user interface (GUI), applications and the kernel. What is an Android kernel? As I said earlier, the kernel is just a part of the ROM. More precisely, the kernel is basically the part that makes to link between hardware and software.
Detailed explanation-2: -All of kernel memory and user process memory is stored in physical memory in the computer (or perhaps on disk if data has been swapped from memory).
Detailed explanation-3: -2) The kernel is loaded into RAM. 3) Kernel performs its initializations and starts scheduling tasks. 4) When a task is loaded, it is given a virtual address space in which it resides.
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. Once data is written on a ROM chip, it cannot be removed.
