Computers can deal with different kinds of problems if they a given the right instructions for what to do. Instructions are first written in one of the high-level languages, e.g. FORTRAN, coBOL, ALGOL, PL/1, PASCAL or BASIC, depending the type of problem to be solved. A program written in one of these languages if often called a source program, and it cannot be directly processed by the computer until it has been compiled, which means interpreted into machine code. Usually instruction written in a high- level a single language, when transformed into machine code, results in several instructions. Here is a brief destructionn of the many high-level language. FORTRAN - acronym for Formula Translation. This language is used for solving scientific and mathematical problems. It consists of algebrai formulae and English phrases. It was first introduced in the United States in 1954.COBOL acronym for Common Business - Oriented Language. This language is used for commercial purposes. COBOL, which is written using English statements, deals with problems that do not involve a lot mathematic calculations. It was first introduced in 1959.ALGOL - acronym for Algorithmic Language. Originally called IAL, which means International Algebraic Language. It is used for mathematical and scientific purposes. ALGOL was first introduced in Europe in 1960.PL/I- Programming Language 1. Developed in 1964 to combine features of COBOL and ALGOL. Consequently, it is used for data as well as scientific applications.BASIC - acronym for Beginner's All-purpose Symbolic Instruction Code. Developed in 1965 at Dartmouth College in the United States for use by students who require a simple language to begin programmingOther such languages are APL (developed in 1962) and PASCAL (named after Blaise Pascal and developed in 1971)
