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


IT experts perform a variety of duties that range from installing applications
to designing complex computer networks and information databases.

They are suitable for data management, networking, engineering computer
hardware, database and software design, as well as the management and
administration of entire systems.


Difference:



The CS engineering programme usually deals with how to build
microprocessors, how to write a compiler etc.

IT is the commercial side of computers - typically 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.



Moreover, while CSE emphases on the foundation of computing, IT as a
discipline focuses on satisfying the computing technology needs of
organisations.

So, in a continuum between principles and application, IT focuses more on
application, with the goal being to apply knowledge of computing sciences for
solving problems.

However, as the foundations of IT are in Computer Science, Indian
universities and colleges deem it feasible to have a CS-based IT programme.

This allows a graduate of the programme to choose a career in CS or IT,
based on their choice and availability of job prospects.

And mostly corporates make little difference between these disciplines while selecting students.
