BTech CSE deals with a broad range of subjects such as Software development, Hardware, Computer Architecture, Integrated electronics and computing, Data Management. In BTech CSE also there are specialization elective in which one can learn about Data Science but obviously it will not be in the details as compared to that of BSc-MSc Data Science and AI or BTech CSE with specialization in Data Science.

Now Data Science is the subject which analyse data and predict the necessary outcomes. For example, you need to invest in share markets. Now you don't know about the shifting of stocks but if you have a history of past day trends then by data analysis you can conclude a point which will be highly probable to invest in order to get the benefit of investment and no loss. This is one kind of example. Data Science is widely use in Prediction such as a relatable example is Covid Waves. We hear about that the third wave of covid will come etc. The procedure they are predicting is that they are taking the day wise data of infections and trying to build up trends and based on that trends and the information of virology they are predicting waves which you can see is quite accurate as in case of 2nd wave of covid in India. So if you learn data science you will have a lot of job opportunities as well as BTech. But as Data Science is a developing field, you will find more scope in the subject compared to that of BTech.
