Apparently, old Microsoft Word .doc files were just a memory dump of how Microsoft Word stored the document in RAM, so in a sense, they were images. Document formats that need to be parsed to create the internal memory working state (e.g., HTML, RTF, etc.) are emphatically not.
A kernel is the core of an operating system. Typically it provides memory safety, interprocess communication, and a way to load both additional modules (for device drivers, etc.) and user space programs (executable files that do not run with kernel privileges, e.g., cannot directly access hardware).
The kernel typically is stored on disk. Kernel address space layout randomization is a newish thing but I don't know if it changes the internal layout or just loads the kernel in a random RAM location. In any case, certainly prior to KASLR and perhaps even with it, the kernel file is laid out byte-for-byte identically to how its loaded into RAM, so that file is referred to as the kernel image. |
