An assembly language allows a software developer to code using words and expressions that can be easier to understand and interpret than the binary or hexadecimal data the computer stores and reads.

Assembly language is a low-level programming language for a computer, or other programmable device specific to a particular computer architecture in contrast to most high- level programming languages, which are generally portable across multiple systems.

Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code. Assembly language uses a mnemonic to represent each low-level machine operation or opcode.

In computer programming, assembly language (alternatively assembler language or symbolic machine code), 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 ...
