answer? 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.

A computer is an electronic machine that processes information—in other words, an information processor: it takes in raw information (or data) at one end, stores it until it's ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. All these processes have a name.
