What’s interesting about the 286/386 transition is: “Protected Mode” came about with the 286, but was still a 16 bit mode. (Random fact: the only way to return to “Real Mode” on a 286 was through a processor reset). The 386 changed Protected Mode into the 32 bit mode we know today. (And added the “Virtual 8086 Mode” for Real Mode programs)
