PROGRAMMING LANGUAGES

Posted by Golden on August 18th, 2010

 

Computer programmers must convert statements from one form to another. Programmers use programming languages to convert ideas into solutions. Both jobs require a thorough understanding of rules. The translator must know the rules of the languages being translated, whereas the programmer must know the structure and standards of computer language. Hence, unless a programmer adheres completely to the grammar of a programming language, even down to the correct punctuation, the computer will be unable to executive the instructions.

 

Programming language is a set of specialized notation for communicating with computer. They provide facilities to translate interpret and execute a computer program.

There are 5 main categories of programming language. These are:

-machine language: this consists of binary digits of ones and zeros. It is the actual language a computer understands since the systems circuitry can interpret and execute the generated codes directly during processing.

 

-low level language: these are English like mnemonic language. It is a symbolic language. It is a language in which symbols and numerals codes represent machine operations and operands.

 

-high level language: they can be divided into 2 categories which are procedure oriented languages and problem oriented languages. They are similar to most human languages; examples are FORTRAN, BASIC, and COBOL.

 

-Fourth generation language: they include a whole range of languages including query language and decision support tools. They are English type words or statements which is much less dependent on the environment.

 

-Fifth generation language: they languages associated with artificial intelligence and expert systems. It is different in structure and usage. These differences includes functional and logic programming languages.
