If the alphabet is 0 1 then 2011 is already not possible as a substring.
Push Down Automata (PDA) are a way to represent the language class called Context Free Languages(CFLs). PDA are abstract devices defined in automata theory. They are similar to Finite Automata(FA), except that they have access to a potentially unlimited amoun of memeory in the form of a single stack. PDA are of two types Deterministic and Non-Deterministic. Every PDA excepts a Formal Language. The language accepted by non-deterministic PDA are precisly the CFLs. If we allow a finite automaton to access two stack instead of just one, we obtain a device much more powerful than a PDA, equivalent to a Turing Machine(TM).
Finite automata are used in linguistics to model the structure and patterns of natural languages, particularly in phonology and morphology. They can represent the rules governing sound changes, word formation, and syntactic structures, helping linguists analyze and understand language processes. Finite automata are also utilized in natural language processing tasks such as text classification, information retrieval, and sentiment analysis.
What is expressive power of a language in automate theory is a language Hierarchy
Automata is a mathematical model used to study computation and language recognition. It can be finite or infinite, deterministic or non-deterministic. A language is a set of strings formed from a certain alphabet, and automata can be used to recognize or generate these strings.

Finite Automata and Regular Expressions are equivalent. Any language that can be represented with a regular expression can be accepted by some finite automaton, and any language accepted by some finite automaton can be represented by a regular expression.
It is an alphabet that was created for s specific language, and not borrowed from another language.
well, i suppose a cavemans grunt could be classed as language, and its doubtful they had an alphabet. so yes, language probably came before the alphabet
There is no language that has 75 alphabets. Most languages only have 1 alphabet.
The alphabet of which language? The English Alphabet only has 26 letters.
The moshi alphabet is moshi monster language.
