Machine Language is one of the low-level programming languages which is the first generation language developed for communicating with a Computer. The definition of a computer remained the same until the end of the 19th century, when the industrial revolution gave rise to machines whose primary purpose was calculating. First Generation: A first generation (programming) language (1GL) is a grouping of programming languages that are machine level languages used to program first-generation computers. However, it was not implemented until 1998. The word "computer" was first used in 1613 in the book The Yong Mans Gleanings by Richard Braithwaite and originally described a human who performed calculations or computations. none (unique language) 1943–45 Plankalkül (concept) Konrad Zuse: none (unique language) 1943–46 ENIAC coding system : John von Neumann, John Mauchly, J. Presper Eckert, Herman Goldstine after Alan Turing. It is written in machine code which represents 0 and 1 binary digits inside the Computer string which makes it easy to understand and perform the operations. The first programmers of ENIAC were Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Meltzer, Fran Bilas, and Ruth Lichterman. Officially, the first programming language for a computer was Plankalkül, developed by Konrad Zuse for the Z3 between 1943 and 1945. Seven years earlier, Zuse had developed and built the world´s first binary digital computer, the Z1. Il B2 First è il titolo che certifica il raggiungimento del livello B2 del del Quadro Comune Europeo di Riferimento per le Lingue (QCER). Questo esame è indicato per coloro che per lavoro desiderano una qualifica di inglese di livello medio-alto o per chi ha l’obiettivo di studiare in lingua inglese . The instructions were given through the front panel switches of these computers, directly to the CPU. When was the word "computer" first used? Konrad Zuse begins work on Plankalkül (Plan Calculus), the first algorithmic programming language, with the goal of creating the theoretical preconditions for the solution of general problems. The oldest computer language still in use is Fortran, invented in 1957. The first computer language was assembly language, but the first high level programming language was Plankalkul.
