In chapter 0000, you saw the details of the 8088 CPU and the 80286 CPU. The 80386 offering was backward compatible to the two previous CPUs, however it represented a fundamental difference in design philosophy. In simple terms, the 80386 CPU was designed with multitasking in mind. The idea was to make the 80386 operate as if it was a bunch of 8088/8086 CPUs, with each able to address its own section of memory. This way a user could have multiple programs loaded at the same time, and the CPU could use 'round robin' processing, so the end user would experience several programs running at the same time.
