What is difference between BS IT and BS CS

What is difference between BS IT and BS CS any body tell me and which field have better scope in future??

Do you mean BSc of IT, and BSc of Computer Science?
Personally I think computer science is a more competitive field with higher job possibilities and is a lot more fun. I am currently studying BSc Computer Science.

IT (I believe) looks at computers in the workplace and the use of software to make documents tailored for a business purpose. Whereas comp science is really a more complex field which looks at building the software/ hardware and how to model computer systems. For this reason I believe comp science is best because there are a lot more possibilities with all this knowledge
