CSE: Computer science engineers areinvolved in many aspects of computing, from the design of individual microprocessors,personal computers and supercomputers to circuit designing and writing software that powers them.

IT:

Information Technology deals with theuse of computers and computer software tostore, protect process, transmit and securely retrieve data. IT professionals perform avariety of tasks that range from installing applications to designing complex computer networks and information databases.The major difference between both these fields 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. To make it short and simple, Computer Science is the creation of software and hardware by using different programming skills. On the other hand, IT is just the selection of the proper software or hardware for the task.

Hope this information is helpful
