When compared with human languages (e.g. English, French, Spanish, etc.), programming languages are very much smaller, much simpler, and are also more precise.  Most programming languages consist of a mixture of English words and mathematical notation; very few programming languages have a base vocabulary exceeding 60 words, although they may also have utility libraries with hundreds of entries which provide optional extra functionality.

Many thousands of different programming languages have been defined, though only a few dozen are in widespread use.  The first publicly available programming language was developed in 1951 by [[Grace Hopper]]. In 1948 Zuse published a paper (in "Archiv der Mathematik") about an early programming language Plankalkül, though this was not actually implemented until 1998.
