The development of high-level languages further defined our role in the market. The computers used batch processing and multiprogramming operating system. The first generation languages, or 1GL, are low-level languages that are machine language. A third-generation programming language (3GL) is a high-level computer programming language that tends to be more machine-independent and programmer-friendly than the machine code of the first-generation and assembly languages of the second-generation, while having a less specific focus to the fourth and fifth generations. Systems programmers wrote software for the tools such as the assemblers and the compilers. The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Fourth-generation language (4GL), Fourth-generation computer programming language. However, it was not implemented until 1998.. Short Code, which was proposed by John Mauchly in 1949, is considered to be the first high-level programming language. In this generation assembly language and high-level programming languages like FORTRAN, COBOL were used. This generation had significant opportunities in jobs and education as the War ended and a post-war economic boom struck America. A generation language may refer to any of the following: 1. The second-generation languages, or 2GL, are also low-level assembly languages. Second generation high-level programming languages came in one of two varieties: those that are compiled such as COBOL and those that are interpreted like APL. They are sometimes used in kernels and hardware drives, but more commonly used for video editing and video games. Applications programmers wrote the code in high-level language to solve various problems. 3. It was designed to represent mathematical expressions in a format readable by human beings. 4GLs are closer to human language than other high-level languages and are accessible to people without formal training as programmers.They allow multiple common operations to be performed with a single programmer-entered command. In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. In this era, we saw a division in responsibilities from low-level languages to high-level languages and functionality. However, the growth in Cold War tensions, the potential for nuclear war and other never before seen threats led to levels of discomfort and uncertainty throughout the generation. 2. Officially, the first programming language for a computer was Plankalkül, developed by Konrad Zuse for the Z3 between 1943 and 1945. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax.
