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 which include mathematics , statistics , digital electronics , computer hardware  and software , programming languages , data structures and algorithms and it draws knowledge from many other disciplines.

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 approach for computer science programs offered allows the students to learn by studying 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 and the student 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

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 .
