The difference between computer science and information technology are given below-
Computer Science: It is the study of computers. We typically learn about hardware and operating systems and things like registers, multitasking kernels, data buses, address buses.
Information Technology is about the study of the use of computers to solve the problems. We study some programming, databases, applications, etc.
Computer Science: It is the science of computers whilst Information Technology may or may not be use computers or any form of computer science to do its evil deeds. Of course there is a big overlap but in general computer science handles the technical working of computers whilst IT is concerned more with information manipulation and the business requirements.
From a very broad perspective, Computer Science is the study of the principles of computing. It helps you better understand how computers solve problems, what are the kinds of problems that a computer can solve and how one would present a problem to a computer. Abstract ideas that rely on fundamental mathematical theories are at the heart of Computer Science. Information Technology is the study of technology that drives Information Systems for businesses. Understanding what technology/tools can best meet the Information management needs of an organization is at the heart of IT.
We can say that a computer science is the study of computer’s design and operation. But Information Technology is the use of the computer for a specific purpose without knowing the details of how the computer is carrying on all these tasks. Aim of IT is to make our information more proffitable by making it recently & attractive.
