Computer Science Engineering deals with design, implementation, management of information system of both software and hardware process. While Information Technology deals with the use of computers and computer software to convert, store, protect process, transmit, and retrieve information, Computer Science is the scientific and practical approach to computation and its applications. The difference between Computer Science and IT is that while CSE deals with the design and development of new software and hardware parts of computer, IT aims at designing, developing, implementing and managing computer-based information systems including software applications and computer hardware.

When computer and communications technologies are combined, the result is Information Technology, or ‘InfoTech’. A computer scientist specializes in the theory of computation and the design of computational systems.
