x86 is a family of little-endian instruction set architectures and extensions. As its namesake indicates, the x86 ISA offers binary compatibility all the way from the original 8086 to modern microarchitectures as well as source code compatibility since the 8080. The architecture is widely used in the desktop and server markets by a number of companies including Intel, AMD, VIA, DM&P, and RDC.
