-In computer science, a low-level programming language is a programming language has a tight relationship to computer hardware cới. From "low" does not mean a low level programming languages have the ability to work less than the high level programming language that this means the order of it very close to machine language.-Low-level programming languages are usually divided into two categories: the first generation and second generation.-First generation:Third-generation programming language, or 1GL, is machine code. It is the only language that the computer processor can understand. Today the programmers almost never write programs directly by machine language because it is not a requirement of the more attention to the details which a high-level language is processed automatically, but also asked them to remember and find the code number for each indicator are used.-The second generation:First generation programming language, or 2GL and also known with other names as the Assembly. However, it is not a machine language, but programmers still need to have knowledge of the processor. So it still is considered a second language. These simple commands to be translated directly out of machine code.
