A vocabulary and set of grammatical rules for instructing a computer to perform specific tasks. The term programming language usually refers to high-level languages, such as
BASIC ,
C ,
C++ ,
COBOL,
FORTRAN,
Ada , and
Pascal.
Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions .
High-level programming languages, while simple compared to human languages, are more complex than the languages the computer actually understands, called machine languages .
Each different type of CPU has its own unique machine language.
MACHINE LANGUAGE
Programming language that can be directly understood and obeyed by a machine (computer) without conversion (translation). Different for each type of CPU, it is the native binary language (comprised of only two characters: 0 and 1) of the computer and is difficult to be read and understood by humans.
LOW LEVEL LANGUAGE
In computer science , a low-level programming language is a programming language that provides little or no abstraction from a computer’s instruction set architecture commands or functions in the language map closely to processor instructions. Generally this refers to either machine code or assembly language .
HIGH LEVEL LANGUAGE
A programming language such as C , FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.
