Programming language

A programming language is a way to represent in a reproducible way actions the programmer intends the computing system to perform. The program written in a programming language typically has to be translated into a code the central processing unit CPU can understand and execute. The programming language allows to define data structures and combine them with logic applied to them. Generally a computer language reflects the state of development of the hardware and its processing power.

Programming languages can generally be divided into two categories:

Compiled languages must first be translated by a compiler from human readable source code to an object code. A linker is often applied to this code to assemble it with existing libraries and runtime environments into a form the computer can run.

Interpreted languages rely on an application, the interpreter, that translates the source code into machine code through pre-existing interfaces. For example, an interpreter would read a line such as this: PRINT "Cookies are yummy!" and call the predefined, platform independent function PRINT inside the interpreter itself where the interpreter then executes the platform dependent function call.

All items come with a short description and a typical way to use the language.
