programming language
Programming language is the language to write source code, which is a plan of soft ware. Programming language is made from English and other languages so we can understand, therefore, computers can not execute the programming language straightaway. To make a computer execute the source code written in programming language, you have to assemble or compile, and translate the programming language into machine language (object code). By translating the source code into those languages simultaneously as executing, it looks as though they are executing the source code itself. Those computers are called 'interpreter type.'
These days, what is called 'script language' is getting popular. It is simplified programming language which has slower processing speed but can easily write small scale program.
Programming languages have several categories according to the level for human being to understand, such as assembly language, advanced language, and fourth generation language. The more difficult the language is, the closer it is to machine language, and more directly it can control computers. The language close to the human being's natural language is called 'high level language' and the language close to machine language is called 'low level language'.
