Second-generation programming language
Appearance
A second-generation programming language is usually considered as some form of assembly language. Such a language is not much more than the direct translation of machine language, the very elementar soap of bits that a digital processor is able to talk.
Since usually each processor has its own machine language, there are many different assembly languages.
Another possible definition of the term is refered in Cobol entry: a language in the spirit of COBOL: abstract and independent of processor internal machine language.
