What is Computer Science? Definition of Computer Science?

Computer science discipline provides the basis for the design and use of a computer, cutting-edge development in robotics, Artificial intelligence, bioinformatics, Network, database system, human-computer interaction, vision and graphics, programming languages, numerical analysis, operating system, software development, algorithm, data structure, and theory of computing etc.

Sub Disciplines of Computer Science? Branches of Computer Science? Areas of study of Computer Science?

The theoretical computer science is a subset of computer science and mathematics. It aims to provide efficient methodologies for practical and everyday computation after studying its nature.
It deals with a wide range of topics e.g. algorithmic, logic, automata theory, computational complexity, Combinatorics, data structure, quantum computation, parallel and distributed computation etc.

Artificial Intelligence is a term used for intelligence in a machine. Machines are programmed to mimic the way of thinking and acting of human and other animals. Artificial Intelligence is an area of computer science that develops intelligence system that has the ability of knowledge and reasoning, Natural language processing and Robotics.

Bioinformatics is an interdisciplinary field of science that develops methods and software tools for storing, retrieving and analysis and understanding of a large amount of biological data. This field of study also uses another discipline like mathematics, information engineering, and computer science applications to solve biological problems.

Computer Networking is an engineering discipline that study and analyzes the communication process in which telecommunication devices or computer system are linked, or networked together to share resources and exchange data. Computer Networking solid mathematical background is required. The important tools of computer networking and telecommunication are Calculus, Linear algebra, Probability and Statistics, Differential equations, Numerical analysis, Calculus, Linear algebra, Probability and Statistics, Differential equations, Numerical analysis. Theoretical and practical implementation of different fields like computer science, information technology, computer engineering, and information technology also required. Good programming skill also needed for it.


A database is an organized/structured way to store information that can easily be accessed, searched, updated and managed. Database a the changes in a computer database, plan, coordinate, modify, test, maintain and implement the database. The software that is using to create and maintain database is called Database Management System (DBMS).
Software development is a systematic process of designing, development, maintenance, and evaluation of software. In software development good analytical thinking to get the user needs, logic and structural thinking, work independently and in groups, good programming skills and concepts of different languages.


Operating System development study covers operating system design, development, implementation from basic structure to synchronization, multiple tasks that execute at the same time and share resources. Context switching, scheduling, deadlock, memory management, dynamic memory allocation. Dynamic address translation, virtual memory, demand paging disk management, scheduling directories, protection and crash recovery, I/O device management, process management, virtual memory, Secondary storage and file system, communication mechanisms are topics that are discussed in an operating system.


Data Structure is a programmatic way of storing information on a computer. So that it can use and retrieve information efficiently and quickly. In data structure we use an array, list, tree, queue stack and other algorithms for different needs of storing data like sorting, searching, listing etc.
Computer Graphic is computational methods of the creation of photorealistic computer graphics of people, objects and environment, intricate 3D geometries, image processing display and user interface design and compelling computer animations.
