Intel 80286

(processor)
(Or "286", "i286") A microprocessor developed by Intel. THe 80286 processor has a 16-bit data bus and incorporates a memory management unit that allowed a limited amount of multitasking. The 80286 only has a segmented MMU while the later processors add a paged MMU "behind" the segmented one.

The 80286 was the processor in the IBM PC AT personal computer.
