It identifies three types of grammar: Unrestricted Grammar (Type 0), Context Sensitive Grammar (Type 1), Context Free Grammar (Type 2), and Regular Grammar (Type 3). The hierarchy categorizes languages accepted by different machines into three types: Unrestricted, Context Sensitive, Context Free, and Regular. • Type 0 grammar, also known as Unrestricted grammar, allows for the efficient modeling of languages with no restrictions on their grammar rules. • Type 1 grammar, also known as Context Sensitive Grammar, is used to represent context-sensitive language. It follows rules such as having multiple symbols on the left side of production rules, not exceeding the right-hand side's number of symbols, and not allowing the rule A → ε unless A is a start symbol. Type 1 grammar should be Type 0, with production in the form of V → T. • Type 2 Grammar, also known as Context Free Grammar, is a type of language that can be represented by the context free grammar (CFG). Its production rule is based on the form A → α, where A is a single non-terminal or a combination of terminals and non-terminals. • Type 3 Grammar, also known as Regular Grammar, describes languages using regular expressions and can be modeled using NFA or DFA. It is the most restricted form of grammar, requiring Type 2 and Type 1 and forming the form of V → T*V / T* or V → VT* / T*.
