The native architecture of x86-64 processors: residing in the 64-bit Mode, lacks of access mode in segmentation, presenting 64-bit architectural-permit linear address space; an adapted IA-32 architecture residing in the Compatibility Mode alongside 64-bit Mode is provided to support most x86 applications
x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.
The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
IA-32 is the first incarnation of x86 that supports 32-bit computing; [4] as a result, the "IA-32" term may be used as a metonym to refer to all x86 versions that support 32-bit computing. [5] [6] Within various programming language directives, IA-32 is still sometimes referred to
