IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. They are suited for data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.
The differences
The CS engineering programme usually deals with how to build micro processors, how to write a compiler etc. IT is the business side of computers - usually dealing with databases, business, and accounting. One way to think of it is that IT deals with the application of computing technology to real life processes and CSE deals with the “science” that facilitates these applications.
