To organize different types of languages and the machines capable of processing them, linguist Noam Chomsky established a four-level hierarchy. Advanced textbooks, including C.K. Nagpal’s approach, strictly categorize computational models based on this hierarchy.

A finite control combined with an infinite storage tape and a read/write head.
Understanding formal languages is not merely an academic exercise. The principles detailed in C.K. Nagpal’s book form the bedrock of several computer science domains: However, I would like to clarify that I
