Define Protected Mode in x86 processor architecture and state its primary advantages over Real Mode.
Ch 15: 32-Bit Protected Mode Architecture
Covers transitioning from 16-bit real mode to 32-bit protected mode, setting the PE bit in CR0, constructing 8-byte segment descriptors (base, limit, access rights), and hardware memory protection rings (Ring 0 vs Ring 3).
