x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. [ 1][ 2] It is used to produce object code for the x86 class of processors. Regarded as a programming language, assembly is machine-specific ...
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.

Type. x86 assembler. License. BSD 2-clause. Website. www .nasm .us. The Netwide Assembler ( NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit ( IA-32) and 64-bit ( x86-64) programs. It is considered one of the most popular assemblers for Linux and x86 chips.
In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers machine code is "the binary representation of a computer program which is actually read and interpreted by the computer.
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 ...
INT is an assembly language instruction for x86 processors that generates a software interrupt. It takes the interrupt number formatted as a byte value. [ 1] When written in assembly language, the instruction is written like this: INT X. where X is the software interrupt that should be generated (0-255). As is customary with machine binary ...
Function prologue and epilogue. In assembly language programming, the function prologue is a few lines of code at the beginning of a function, which prepare the stack and registers for use within the function. Similarly, the function epilogue appears at the end of the function, and restores the stack and registers to the state they were in ...
High-Level Assembly ( HLA) is a language developed by Randall Hyde that allows the use of higher-level language constructs to aid both beginners and advanced assembly developers. It supports advanced data types and object-oriented programming. It uses a syntax loosely based on several high-level programming languages (HLLs), such as Pascal, Ada ...
