Assembly language Assembly Language and High-Level Languages
Programmers writing code in compiled high level languages use a program called a compiler to transform their code into assembly language. Compilers are much harder to write than assemblers are. Also, high-level languages do not always allow programmers to use all the features of the processor. This is because high-level languages are designed to support all processor families. Unlike assembly languages, that only support one type of processor, high-level languages are portable.
