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.

Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a viable target for a C compiler.
Assembly language (ASM) introduced mnemonics to simplify this process, making it one of the earliest programming languages still in use today. Numerous dialects and implementations exist, each tailored to a specific computer processor architecture. Assembly languages are low-level and more challenging to use, as they are untyped and rigid. For ...
VAX MACRO is the computer assembly language implementing the VAX instruction set architecture for the OpenVMS operating system, originally released by Digital Equipment Corporation (DEC) in 1977. The syntax, directives, macro language, and lexical substitution operators of VAX MACRO formerly appeared in MACRO-11 , the assembler for the PDP-11 ...
A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture; commands or functions in the language are structurally similar to a processor's instructions. Generally, this refers to either machine code or assembly language. Because of the low (hence the word ...
The four basic arithmetic operations have assembly instructions like ADD, SUB, MUL, and DIV. [46] Computers also have instructions like DW (Define Word) to reserve memory cells. Then the MOV instruction can copy integers between registers and memory. The basic structure of an assembly language statement is a label, operation, operand, and ...
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 .
x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
