Dear candidate!
B.Sc Computer Science is a 3-year undergraduate degree, specialising in computer science. The course focuses on basic concepts in the field of computer science and technological implementations of computers, providing you with a strong academic foundation in the field of computer science. Topics studied in B.Sc Computer Science include programming concepts, disk operating systems, and control structures.

B.Tech CS is a 4-year undergraduate professional course, which is essentially a degree in the field of engineering with a specialization in computer science. In B.Tech CS, you would study computers in-depth, including their software, hardware, concepts and applications. The B.Tech CS course was one of the first courses in the field of computer science to be offered in India and has immense prestige. Topics studied in B.Tech CS include digital circuits & system, data structures, operating systems, database management systems, and computer architecture.

The core difference between the two:
B.Sc Computer Science

Programming Fundamentals Using C++

Computer System Architecture

Data Structures

Design and Analysis of Algorithms

Database Management Systems

Internet Technologies

Theory of Computation

Computer Graphics



B.Tech Computer Science

Programming Fundamentals Using C++

Web Technologies

Management Systems

Multimedia Technologies

Applied Mathematics

Applied Physics

Applied Chemistry

Database Management Systems/Data Mining

Theory of Computation

Engineering Mechanics

Algorithm Analysis & Design

B.Tech according to me is a more professional course and give you better job opportunities as compared to B.Sc. Yes if you want to follow a path of academics then B.Sc. M.Sc. And Ph.D. would be a perfect way to become a professor in a reputed university. But he fact is you need a good university to support you with best academics.

I give you all the details as well as my opinion now it's up to you in which field you are interested and you want to take it as a career and which will be best for you and with will have a good scope for you so is all about your future I can guide you but you have to take a very good decision thinking of all the pros and cons so choose wisely.
Hope this will be helpful for you.
Regards!

B.Sc. Computer Science is a 3 year undergraduate specialisation course in the field of computer Science, teaching the various aspects of computer Science and its applications which includes programming, software development, etc. It also involves software development and testing, networks, programming, etc not according to the quantity and level of b.tech . B.Tech CSE is a 4-year undergraduate engineering course with more advanced practical and theoretical knowledge of computer hardware and software than B.Sc. Practical knowledge of a B.Tech in CS graduate and B.Sc CS graduate will be different.
