X86 is a family of backward-compatible instruction set architectures[a]
based on the Intel 8086 CPU and its Intel 8088 variant. The 8086 was
introduced in 1978 as a fully 16-bit extension of Intel's 8-bit-based 8080
microprocessor, with memory segmentation as a solution for addressing more
memory than can be covered by a plain 16-bit address. The term "x86" came
