What is the difference between computer science and IT?

Let me first discuss the technical differences. CS takes a more balanced approach between theory and application, while IT focuses more on application. CS offers you an opportunity to learn variety of topics related to computers. IT offers you an opportunity to discover innovative uses of those fundamental concepts. CS generally require a decent background in mathematics, while use of math in IT is limited to data analysis / processing / statistics, etc. You may call IT as one of the sub-divisions of CS, however there are certain things that are unique to IT like integrated programming, system administrations, maintenance, etc. While these differences exist on paper, in India the line of difference between IT and CS courses is very blurry. Here are the similarities: None of them involves hardware. You may have to take one or two courses on digital systems where you will study about ICs and logic gates. You won’t learn how to repair computers in any of them. Most of the courses offered in both the branches are related to programming. You will have to program on a daily basis in both the branches.

Computer science engineers are involved in many aspects of computing, from the design of individual microprocessors, personal computers and supercomputers to circuit designing and writing software that powers them. Information technology deals with the use of electronic computers and computer software to store, protect process, transmit and securely retrieve data. IT professionals perform a variety 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 skill. On the other hand, IT is just the selection of the proper software or hardware for the task. Both are good course, choose the course in which you are interested in.
