"

The term computer language is sometimes used interchangeably with programming language[2] but some contend they are different concepts. Some contend that programming languages are a subset of computer languages.[3] Some use computer language to classify a language used in computing that is not considered a programming language.[citation needed] Some regard a programming language as a theoretical construct for programming an abstract machine, and a computer language as the subset thereof that runs on a physical computer, which has finite hardware resources.[4]
