It is important to keep in mind that assembly language is a lowlevel language, so instructions in assembly language are closely related to their 32bit representation in machine language. Assembly language is a lowlevel programming language for a computer or other programmable device specific to a particular computer architecture in contrast to most highlevel programming languages, which are generally portable across multiple systems. But in the past, data structures were more easily built with assembly language than with the other programming languages of the time.
