The 80386 and successors support the 80286's 16-bit segments reuse the technique for 32-bit address offsets. If the base address of all 32-bit segments is set to 0, and segment registers are not used explicitly, the segmentation can be forgotten and the processor appears as having a simple linear 32-bit address space. Operating systems like Windows or OS/2 provide the possibility
