Computer Science Subjects

Computer Science is the study of systems that can be used to solve complex data problems through computation and critical thinking. It encompasses the study of computers and algorithmic processes, including their principles, hardware and software designs and their applications. Being one of the most pursued degree courses after 12th Science, the career opportunities in this field are vast. Be it BSc Computer Science, Diploma in Computer Science, Computer Science Engineering or MBA in Computer Science, the diverse curriculum of these programs develops the analytical thinking skills of students and allows them to visualize different perspectives to a problem. The knowledge and the skills acquired through an array of Computer Science subjects can be put to use in various fields like Weather Forecasting, Healthcare, Finance, Gaming, etc. In this blog, we will shed light on some of the popular subjects taught in the graduation and post-graduation degree programs in this field. 

1. Data Structures

Data Structures is a branch of computer science that specifies the information related to data and how to store/organize it. It enforces different ways (or specifications) to achieve the objective according to one’s requirement. There are primitive data types like (int, float, char) and there are ones that are derived out of primitive data type (array, binary tree, class). The students through this famous Computer Science subject get acquainted with the skills to use a data structure based on varied situations so as to make the whole work a lot easier and efficient.

2. Microcontrollers and Embedded Systems

Microcontrollers and embedded systems is a field in which the study of small, self-contained systems is done. Microcontrollers are small scale working computers that consist of processor, memory and input/output (I/O) peripherals that perform a specific function of the embedded systems. Due to them being cheap and small in size, they have a large number of applications when paired with accessories like sensors, displays, motors, etc. Taught in both Electrical and Computer Science subjects, the curriculum consists of topics like data transfer, I/O ports, hardware interfacing, etc. Such systems are actively used in applications like creating remote control toys, home automation, measuring devices, healthcare to name a few.

3. Object-Oriented Programming

Object-Oriented Programming is one of the ways of programming, based on the concept of objects. There are different ways of programming like Procedural, Structural, Object-Oriented Programming(OOP), etc. And out of all, OOP is the predominant Programming paradigm used nowadays. The reason for its widespread adoption is because it incorporates features like polymorphism, inheritance, and abstraction which enables the same program to work differently according to varied requirements. This, in turn, reduces the time required for designing and creating programs. Java, C++, GUIs, etc are some of the major topics taught in the subject.

4. Discrete Mathematics

This field is an intersection of mathematics and computer science. The end product is a subset of mathematics that is generally required in most computer science applications. The syllabus covered in this field is different than “Continuous Mathematics” which involves disciplines like Trigonometry, Integration, Differentiation, etc. This subject includes topics like Sets, Relations and function, prime numbers which are required in higher studies of any branch of computer science.

5. Algorithm Analysis and Design

This is one of the Computer Science subjects which imparts knowldege and equips the students with the skills to perform a theoretical approximation of the required resource and solve a specific computational problem. This branch deals with “Time Complexity” of a given algorithm and works on methods to make it more efficient. An algorithm’s worst, best, average and amortized analysis is done to get its efficiency and then appropriate steps are taken to make them according to the available environment.

6. Cryptography

Cryptography, which etymologically is the ‘Study of solving codes’ is one of the lesser-known Computer Science subjects. It is one of those passive roots of computer science which is used in everyday life without one being aware of them. This field involves the study of codifying unreadable text so as to ensure complete security. The ‘https’ (hypertext transfer protocol secure), which you find on the page you visit in layman’s term means the site is secured. For ‘https’ to work in the background, cryptographic protocols are implemented such as ‘TLS’. Further, we can making online transactions safely is also possible due to cryptographic protocols being in place. Message Integrity, encryption, digital signatures, block ciphers, etc are some of the topics taught in the subject. 

Note: The topics mentioned have been referred form the Cryptography Certificate course at Stanford University. The syllabus of this subject can vary from one university to another. 

7. Network Security

Network Security is the study of practices adopted to ensure the safety and authenticity of a computer network. One of the popular Computer Science subjects, it ensures that only legitimate users have access to the network and it’s desired resources. Through the Networking courses, the learners are taught to implement different technologies like VPN, Firewall Packet Filter, Proxy, etc, to ensure the total security of a network. 

Apart from the aforementioned modules, there are some emerging Computer Science subjects that are now being taught under various programs. Some of these have been tabulated below:  

E-Commerce  Machine Learning
Web Technology Big Data Analytics
Electronics Bioinformatics
Programming Languages Computer Graphics

Thus, the knowldege acquired through Computer Science subjects can be put to use in an array of fields. If you are planning to pursue a course in this field abroad but are not sure about how to get started with it then the experts at Leverage Edu will lend you a helping hand. From completing the admission related formalities to preparing for visa interviews, the counselors will provide assistance at every step!
