Programming languages and programming systems
programmers productivity began to apply languages programming, not consoling with absolute languages. On COMPUTER of the third generation an absolute language practically is not used for programming of tasks, the role of internal language of COMPUTER was saved only after him. Several hundred different languages are presently counted programming which are classified on different signs. Most general is classification on the degree of dependence of language from COMPUTER. On this sign languages are divided by two large groups: • Computer-dependent languages, • Computer-independent languages. Computer-dependent languages, in turn, divide by machine and machine-oriented. An absolute language is a programming language, directly perceived by a computer. Every command of absolute language is interpreted by an apparatus, executing the indicated functions. Commands of absolute language in principle are enough primitive. The only corresponding association of these commands in the programs in absolute language enables to describe serious enough algorithms. The sets of commands of absolute language of modern computers include some very effective possibilities frequently. It is said that an absolute language is computer-dependent: the program, written in absolute language of computer of one type, as a rule, can not be executed on the computer of other type, if its absolute language is not identical to the absolute language of the first computer (or is not expansion in relation to this language). By another sign machine, or by a vehicle, there is character of commands dependence: in the commands of
