A '''first-generation programming language''' ('''1GL''') is a [[machine code|machine-level]] [[programming language]] and belongs to the [[Low-level programming language|low-level programming languages]].<ref name="Computer Hope">[http://www.computerhope.com/jargon/num/1gl.htm "Computer Hope, Generation languages"]</ref><br />
<br />
The first-[[programming language generations|generation programming languages]] (1GL) are a grouping of programming languages that are machine-level languages used to program [[first-generation computer]]s. Originally, no [[translator]] was used to [[compiler|compile]] or [[assembly language|assemble]] a first-generation language. The first-generation programming instructions were entered through the [[front panel]] switches of the computer system.<br />
<br />
The instructions in a 1GL are made of [[binary number]]s, represented by 1s and 0s. This makes the language suitable for the understanding of the machine but far more difficult to interpret and learn by the human programmer.<br />
<br />
The main advantage of programming in 1GL is that the code can run very fast and very efficiently, precisely because the instructions are executed directly by the [[central processing unit]] (CPU). One of the main disadvantages of programming in a [[Low-level programming language|low-level language]] is that, when an error occurs, the code is not as easy to fix.<br />
<br />
First-generation languages are very much adapted to a specific computer and CPU, and code portability is therefore significantly reduced in comparison to [[high-level programming language|higher-level languages]].<br />
<br />
Modern-day programmers still occasionally use machine-level code, especially when programming lower-level functions of the system, such as [[device driver|drivers]], [[interface (computing)#Hardware interfaces|interfaces]] with [[firmware]], and hardware devices. Modern tools such as native-code compilers are used to produce machine-level code from a higher-level language.<br />
