How Many Subjects Are There in Computer Science Engineering?

In most universities and colleges, during a period of 8 semesters, you will study approximately 50-55 subjects, depending on the ratio of elective subjects and projects in engineering studies.

The computer science syllabus includes a subject breakdown semester-wise with a reasonable balance of the theoretical components and the practical subject components of coding and project work. You’ll also explore various computer science project ideas as part of your coursework, especially in the later semesters.

Core Subjects in Computer Science Engineering

Every BE Computer Science Engineering student studies a few common subjects that build a foundation for further studies. These are the important topics you would typically encounter in almost every syllabus of computer science:

Data Structures and Algorithms (DSA):
DSA focuses on how to effectively organize and manipulate data efficiently, using algorithms to make problem solving easier and quicker.
Computer Networks:
Computer networking looks at how computers communicate wired and wirelessly, using the internet and protocols to transfer data.
Database Management Systems (DBMS):
Covers how to store, organize, and manage data using relational databases like MySQL or Oracle.
Operating Systems (OS):
Teaches how software interacts with hardware, handling processes, memory, and file systems in computers.
Software Engineering:
Software Engineering is the discipline of establishing principles and practices for the design, developing, testing, and maintaining of software projects.
Theory of Computation (TOC):
The theory of computation is about the mathematical models of computation and their capabilities, which include understanding what can and cannot be solved in computing within CS.
Compiler Design:
Explains how programming languages are translated into machine code through lexical, syntax, and semantic analysis.
Artificial Intelligence (AI):
Introduces approaches for creating intelligent systems that can imitate human decision-making and problem-solving.
Machine Learning (ML):
A subfield of AI where systems are able to learn from data and recognize patterns, thereby improving performance without being explicitly programmed to do so. There are many online certifications for engineering students that cover machine learning fundamentals and practical applications, helping students build valuable skills in this area.

Career Options After Studying Computer Science Subjects

Studying the computer science engineering syllabus opens up career paths such as:
