Theory of Computation: Regular Languages – Introduction | Regular Languages | TOC

**Topic:** *Regular Languages – Introduction*

In this video, you will learn:

* What **Regular Languages** are in Theory of Computation
* The **basic idea behind regular languages**
* How regular languages are defined using **finite automata**
* The relationship between **regular languages, regular expressions, and finite automata**
* Examples to understand **regular language patterns**

In **Theory of Computation**, a **regular language** is a language that can be **recognized by a Finite Automaton (FA)**.

Regular languages form the **simplest class of languages in the Chomsky Hierarchy** and are widely used in many areas of computer science.

Regular languages can be described using:

* **Deterministic Finite Automata (DFA)**
* **Non-Deterministic Finite Automata (NFA)**
* **Regular Expressions**

Example of a regular language:

L = { w | w contains only symbols 0 and 1 }

Example strings:

0, 1, 01, 10, 0011, 1010

Regular languages are widely used in:

* **Compiler Design (Lexical Analysis)**
* **Pattern Matching**
* **Text Processing**
* **Programming Language Processing**

Understanding regular languages is essential for learning:

* **Finite Automata**
* **Regular Expressions**
* **Language recognition**
* **Automata theory**

Questions related to **regular languages and finite automata** are frequently asked in **university exams, GATE, UGC NET, and other competitive exams**.
