Chomsky Hierarchy  Computerphile  Summary and Q&A
TL;DR
Finite State Automaton are a type of Turing machine that require a finite amount of memory and have predictable RAM requirements.
Questions & Answers
Q: What is the role of finite state automaton within the hierarchy of Turing machines?
Finite state automaton occupy a position within the hierarchy of Turing machines, where they have a predictable and finite amount of RAM requirements. They are less demanding in terms of memory than other types of Turing machines.
Q: How are finite state automaton related to Noam Chomsky and linguistics?
Noam Chomsky, a linguist, contributed to the understanding of finite state automaton by studying simple languages with restricted structures. He discovered the different types of Turing machines and their relationship to language complexity.
Q: Can finite state automaton be used to represent computer languages?
Yes, finite state automaton can be used to represent computer languages. They provide a framework for understanding the structure and behavior of programming languages and how they can be compiled or interpreted.
Q: What is the significance of the Inner Circle of Type 1 in the diagram?
The Inner Circle of Type 1 represents a subset of Turing machines that have predictable RAM requirements. This means that their memory usage can be determined in advance, making them more efficient and easier to analyze.
Summary & Key Takeaways

Finite State Automaton sit within a hierarchy of Turing machines, with each level having different demands on memory and computational power.

There are subsets of Turing machines that have predictable RAM requirements, such as those in the Inner Circle of Type 1 in the diagram.

Noam Chomsky, a linguist, made significant contributions to the understanding of finite state automaton and their relationship to natural and computer languages.
