What is assembly language?

Assembly language (ASM) is a low-level programming language that is compiled by an assembler. Every assembler is designed for a specific computer architecture. Programmers can write human-readable programs, using assembly language, that correspond to machine language.

Assembly languages are tied to specific computer architecture and are not portable.
