A computer language is a formal language for humans to communicate with a computer; not a natural language. In earlier days of computing (before the 1980s), the term was used interchangeably with programming language, but today, used primarily for taxonomy, is a broader term that encompasses languages that are not programming in nature. Sub-categories (with possibly contended hierarchical relationships) include:

• Construction

• Programming – for controlling computer behavior

• Command – for controlling the tasks of a computer, such as starting programs

• Query – for querying databases and information systems

• Transformation – for transforming the text of a formal language into text that meets a specific goal

• Structural

• Configuration – for writing configuration files

• Data exchange – examples: JSON, XML

• Markup – for annotating a document in a way that is syntactically distinguishable from the text, such as HTML

• Page description – for describing the appearance of a printed page in a higher level than an actual output bitmap

• Style sheet – for expressing the presentation of structured documents, such as CSS

• Modeling – for designing systems

• Architecture description – for describing and representing system architecture

• Hardware description – for modeling integrated circuits

• Simulation – for simulating

• Specification – for describing what a system should do
