There are some differences between the Computer Science and Information Technology branches. IT mostly deals with the software component but CS entails a lot of other things. It usually acts like a conduit between IT and electronics. You'll get to learn about hardware component also in CS. 

The major difference between both these field is that IT deals with the application of computing technology to real life processes, while, Computer Science deals with the science that facilitates these applications.On the other hand, IT is just the selection of the proper software or hardware for the task.Computer Science is creation of softwares and hardwares by using different programming skills.

IT is just the selection of the proper software or hardwares for the task

In other words CSE create the software and IT engineers use it to solve various problems.

Both have equal scope but I have heard that IT field is becoming saturated due to lots of IT engineers. CSE is more profitable according to me as you can survive in this field easily as lots of jobs are available and if you create great softwares you will be at the top of the pinnacle.
