**Theory of Computation Lab Manual Notes:** Theory of Computation Lab Manual is an important part of the practical component of the subject of Computation Theory. While theoretical knowledge is enough for the basic understanding of any subject, students require a practical or laboratory component to fully understand a subject and be able to apply it practically.

The Theory of Computation Lab Manual allows students to put to proper use the theoretical knowledge that they have learnt of the subject of Computer Science. We believe that no study is complete without inculcating in it several components, including the practical component to learn how various concepts work in real life. Students can refer to the Big Data Lecture Notes For CSE as per the latest and updated syllabus from this article.

Every student should have the resources to secure good marks in their examinations. We have provided the following reference materials for the subject Theory of Computation Lab Manual for all the students who require it.

Theory of Computation is also known as Automata Theory, whose name comes closely from the word ‘automation’ in English. This theory was established by computer scientists to look at, understand and describe the behaviour of discrete systems in computers. The Theory of Computation holds immense importance in not only Computer Science, but also in the subject of Mathematics.

The reason why the subject is also referred to as ‘Automata’ Theory is because it looks at discrete series functioning in simple automated objects, or simple machines. These simple machines are also called automata, and thus, the name Automata Theory.

Theory of Computation and Theory of Computation Lab Manual include the following topics:

- Symbols
- Alphabets
- String
- Language
- Cardinality, among other topics.

### Theory of Computation Lab Manual Reference Books

The vitality of reference books in a student’s life extends to whether or not she or he would like to gain knowledge from outside the classroom. For any subject or topic, the more you read, the better you fare in the knowledge you gain – this holds true for anything.

In a similar manner, we must understand the role that reference books play in a student’s life. They take your knowledge and understanding of a subject from much beyond the classroom. Reading a book about a subject allows you to interpret it and learn what it says in your own way, which is why it’s very helpful.

To carry out the experiments in the Theory of Computation Lab Manual, we must first have a clear understanding of the subject at hand. Naturally, before we can apply a concept practically, it should be crystal clearly understood by us first.

Below, there is a list of reference books for theoretical knowledge about the Theory of Computation. Using these reference books, you will find it easier to carry out experiments for the Theory of Computation Lab Manual.

Here is the list of Theory of Computation reference books to understand the Lab Manual:

- Introduction to the Theory of Computation – by Michael Sipser
- Introduction to Automata Theory, Languages and Computation – by Jeffrey Ullman and John Hopcroft
- Introduction to Computer Theory – by Daniel Cohen
- Theory of Computer Science – by K.L.P. Mishra
- Elements of the Theory of Computation – by Papadimitriou and Lewis Harry
- Elements of Computation Theory – by Arindama Sing.

### Theory of Computation Lab Manual Curriculum
