Type 1 known as Context Sensitive Grammar. Type 2 known as Context Free Grammar. Type 3 Regular Grammar. This is a hierarchy. Therefore every language of type 3 is also of type 2, 1 and 0. Ver mais Type 0 grammar is known as Unrestricted grammar. There is no restriction on the grammar rules of these types of languages. These languages can be efficiently modeled by Turing machines. For example: Ver mais Type 1 grammar is known as Context Sensitive Grammar. The context sensitive grammar is used to represent context sensitive language. The context sensitive grammar follows the … Ver mais Type 3 Grammar is known as Regular Grammar. Regular languages are those languages which can be described using regular expressions. … Ver mais Type 2 Grammar is known as Context Free Grammar.
