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.

While 386 PCs already run OS/2 (the operating system developed by IBM and Microsoft as a successor to MS-DOS), the current version is just as appropriate for the PC/AT's single-tasking 80286 microprocessor and 16-bit architecture as for the more powerful 386.

Although some of the machines' CPUs could run Unix, even the 16-bit Intel 80286 microprocessors operating at 25 MHz inside IBM PC/ATs and their clones did not provide true multitasking, so that engineering and other compute-intensive programs operated too slowly for some users' pace.
