x86 is a family of architectures developed by Intel.

It was named after the 8086, which in turn was a 16-bit variant of Intel's 8080 microprocessor.

The 16-bit and 32-bit microprocessors in the X86 family were commonly referred to as IBM PC compatible. As a result, computers that run on the x86 architecture are commonly known as PCs.
