The Intel 80286, commonly called the 286 processor, was one of the most important microprocessors ever produced. Released by Intel in February 1982, the 286 represented a major technological leap beyond the earlier 8086 and 8088 processors used in the first generation of IBM Personal Computers.

While modern processors contain billions of transistors and operate at speeds measured in gigahertz, the 286 marked the beginning of advanced PC computing. It introduced features such as memory protection, multitasking support, and expanded memory addressing that would influence computer architecture for decades.

Many historians consider the 286 to be the processor that transformed personal computers from hobbyist and office machines into serious business workstations.
