The physical and virtual storage spaces in the Linux system have a range of addresses ranging from 0x00000000 to 0xFFFFFFFF, with 4GB in total, but physical storage space is completely different from the virtual storage space layout. Linux runs in virtual storage space and is responsible for mapping the actual physical memory in the system, which is much less than 4GB, to the entire 4GB virtual storage space based on different requirements. Linux works primarily in protected mode. The 80x86 has
