What Is Computer Science ?

In most simple terms , computer science is the study of computer design , architecture and the application of this knowledge in actual practice.

The computer science is also  defined as  a  branch  of  engineering  science that deals with the study of computer technology , its design principles and applications of the computer system in various fields.

The computers have occupied a indispensable position in human world  and  we are moving towards the machine age . The applications of computer science in every spear of human activity have transformed  the world around us .

Why Computer Science Is Interdisciplinary ?

The computer science is said to be an interdisciplinary science . The computer science fields of study involves combining many disciplines.

The computer science fields of study include mathematics , statistics , digital electronics , computer hardware  and software , programming languages , data structures and algorithms.

The CS also draws knowledge from many other disciplines such as electrical engineering , data science and digital electronics.

There are many fields of study in computer science which do not fall exactly  into  a particular discipline but rather into a overlapping of two or more disciplines .

And therefore , the computer science fields of study includes the study of many inter related disciplines .

Computer Science Is Interdisciplinary

The interdisciplinary nature of CS and the approach for computer science programs offered allows the students to learn by studying different disciplines and their interrelationship.

This approach also helps the students to study the conceptual connections between the theoretical principles and how its applications that are spread across different disciplines.

In this approach the  students are able to simultaneously apply the knowledge gained in one discipline into other disciplines  in order to enhance their learning experience.

Computer Science Research Areas

The field of computer science spans across several core areas such as theoretical computer science, computer hardware systems, software systems, database systems , discrete mathematics and scientific computing.

Since the scope of computer science fields is pretty vast , the students need to be aware of the these sub-disciplines with varying levels of specialization depending on the desired application of the computer science degree.

Although in most degree courses the  specialization will come into effect  at the graduate level. However , It is important for student to know the existence various sub-disciplines within computer science.

The students can then opt for an appropriate area of specialization depending upon the personal preference and the scope of the course curriculum .

Data Structures

The efficiency of the software application also depends upon how efficiently the program data is handled and manipulated by the program . The program needs a formal structure to represent the data and the permitted operations on these data items .

The data structure is a manner in which the data ( Information ) is organized and represents the relationship amongst various data elements . The data structure also defines the set of operations allowed and that can be performed on the data elements

Data Structure Types
Primitive Data Structures

The most common operations allowed in a particular data structure might include data storage , data deletion , data search and data sorting .

The study of data structure helps the computer science students to develop a robust underlying structure for program to efficiently organize the program data and the set of operations designed to operate on the data .


Each computer program implements a specific algorithm . The  Efficiency  of  the  computer system  to solve a particular problem depends upon  the  efficiency  of the program code  which  directs the computer to solve that problem  in a particular manner.

Before writing a computer program code , the programmer has to first decide the logic of the program and then translate this logic in to the sequence of logical steps , which implements that logic  to solve  the problem  in a particular manner .

This procedure represented in terms of logical steps which leads to solution is referred as algorithm .

There can be many possible solution to a problem. And therefore , a programmers must logically think  and explore different  algorithms to find  the best possible algorithm that provides the solution  which is most efficient .

The external hardware components are also referred as peripheral devices such as mouse , monitor , keyboard , printer , speaker and so on .

The computer technology is rapidly evolving due to technological inventions in both software and hardware domain .

 The study of hardware component and the hardware technology helps the computer science students to develop interest in this computer science fields of study .

Computer Science Fields Of Study

Computer Software

The computer system consist of both  software and hardware components . The study of computer software components  is an important discipline within the  computer science fields of study .

The study of software components can be split into two sub-disciplines  which includes

Application Software

System Software

The application software are developed for system users to provide an interface to perform a specific task on the computer system .

Whereas the system software components are developed by the system components manufacturing companies . The system software is a special software  which is necessary to interact with the specific hardware components .

Both application software and system software are highly specialist major disciplines within computer science fields of study. Most computer science students generally opt for any one of these fields of study  for specialization .

Computer System Architecture

The computer architecture is a specialist discipline within a computer science which defines the system features and specifications .

The system architects specify the specifications to be used  for designing a computer system  or a  platform .

The computer architecture provides the details of the software technology and hardware components to be used to design  a computer  system   or   a platform in terms of technical features and the performance parameters .

The system architectural specifications may not endorse a specific brand for the components to be used .

Computer System Architecture

The study of computer system Architecture is a specialization within computer science fields of study . This field helps the computer science students to develop expertise as a  system architect .

Computer Programming

The computer needs to be directed in order to execute any task on the computer system . And therefore , computer program is essential feature of every computer system.

The computer program consists of number of program statements and each of these statement performs a specific task.

The computer system understands only binary language which consists of only two numbers that is 0 and 1. However , writing a program in binary is very difficult and hence, computer programs are usually written using programming language which is human friendly.

The computer programs written in using any programming language and later on converted to machine code in binary by using a special program called compiler. This compiled code is executed by the computer.

Programming Languages , Computer science Fields of Study
Program Compilation , CS Fields Of Study

There are many programming languages used for computer programming . Each of these programming language is best suited for developing a particular type of software application.

Some of the most popular languages include C , C++ , Java , Python , JavaScript , GO , C# ( C Sharp ) , PHP , Kotlin , MS .Net , SQL and there are many more .

The programming language is one of the most popular computer science fields of study that attracts large number of students as a career option.
