Assembly Language

An assembly language is a low-level programming

language for a computer, or other programmable
device, in which there is a very strong (generally
one-to-one) correspondence between the language
and the architecture's machine code instructions.
Each assembly language is 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.
