real mode, protected mode and long mode real mode, protected mode and long mode Or: 16-bit modes (real, protected or virtual), 32-bit mode (protected), 64-bit modes
Real mode uses 16 bit data path while protected mode uses 32 bit data path.
processor contain three modes. 1.Real mode -When PC in DOS programing. 2.Protected Mode -When PC operating system mode 3.virtual mode real mode - when PC in protected and real mode conmmenly.
In real mode far pointers are 32 bit long (segment + offset) In protected mode 48 bit (16 bit segment + 32 bit offset) (In 64-bit mode 80 bit (16 nit segment + 64 bit offset) but it's not so useful)

no. protected mode runs the software in a "sand box" where nothing should be able to go wrong. 16-bit mode runs the program using 16-bit instead of 32-bit, for compatability.
Real mode -16bit Protected mode -32bit
yes
32-bit flat memory mode.
