平均值和中位数的背离，进一步印证了上述趋势——一方面，研发人员数量平均值由上年的722人提升至731 人；另一方面，研发人员的中位数却从上年的216 人降至213 人。这意味着，少数研发密集型企业大量增聘研发人员，多数中小型企业的团队规模维持稳定或略有收缩。
The 80286 introduced "Protected Mode" in 1982. It was not popular. The mode was difficult to use, lacked paging, and offered no way to return to real mode without a hardware reset. The 80386, arriving three years later, made protection usable -- adding paging, a flat 32-bit address space, per-page User/Supervisor control, and Virtual 8086 mode so that DOS programs could run inside a protected multitasking system.
