Difference between Natural Language and Computer Language
|Natural Language||Computer Language|
|Natural language has a very large vocabulary.||Computer language has a very limited vocabulary.|
|Natural language is easily understood by humans.||Computer language is easily understood by the machines.|
|Natural language is ambiguous in nature.||Computer language is unambiguous.|
