Whereas, B.tech CSE with Artificial Intelligence is also a bachelor's program in computer science but with an upgradation. It has Artificial Intelligence specialisation. Artificial Intelligence is a process in which unstructured data and automate tasks that required human intelligence such as extracting meaning from images, text, speech, making decisions is done.

And, B.tech CSE with Cyber Security is bachelor's degree in Computer Science with Cyber Security specialisation. Cyber Security is the techniques of protecting computers, networks, programs and data from unauthorized access.
