Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
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]
In computing, protected mode, also called protected virtual address mode, [1] is an operational mode of x86-compatible central processing units (CPUs). It allows system software to use features such as segmentation, virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software.
A "Hello, World!" program is usually a simple computer program that emits (or displays) to the screen (often the console ) a message similar to "Hello, World!". A small piece of code in most general-purpose programming languages , this program is used to illustrate a language's basic syntax .
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.

Support for the various x86 memory models was provided by inline assembly, compiler options, and language extensions such as the "absolute" keyword. The Turbo Assembler , TASM, a standard x86 assembler independent of TP, and source-compatible with the widely used Microsoft Macro Assembler MASM, was supplied with the enhanced "Borland Pascal ...
