Algorithm is a prescribed set of well defined rules or instructions for the solution of the problem. Algorithmic language is a language or notation used to express clearly an algorithm.

 1) Linear - Линейный  2) Branching - Разветвляющийся  3) Loop (Cycle) - Циклический

 High level language – A variety of programming language in which the control and data structures reflect the requirements of the problem. It is translated in to machine code by compiler.(Pascal, Delphi, C, C++, etc)  Low level language – A variety of programming language in which the control and data structures directly reflect the underlying machine architecture(Assembler, CIL, etc)
