Computer Science is basically concerned with the study of computers. A student of Computer Science learns about hardware and operating systems. It is also about highly technical stuff like registers, multitasking kernels, databases and address buses. It is said to be about the principles of computing and about the design of the computer and its operation. Computer science is concerned only with computers while it is not so with Information technology.
Information Technology on the other hand is about how the computer can be employed to various operations in life. Thus it concerned with the study of applying computer science to day-to-day human operations in industries and businesses. A student of Information technology would deal with subjects like programming, databases, software, application etc rather than the actual operation of the computer itself. Thus IT is about the use of the computer for certain functions that would make work easier and better without actual delving into the details of computer operations.
Information Technology- Deals with the technologies used by people and businesses every day. This includes phones, computers, networks, video conferencing, etc..
Computer Science- An academic field devoted to the study of computing, including a wide variety of scientific, mathematical, and practical problems which can be solved using computers. While Computer Science does teach about the computer itself, it also studies the underlying ideas behind computing and how computers can be used to study other problems.
Heres an analogy... think of how an astronomer uses a telescope to study the stars. Yes, the astronomer needs to know how to use the telescope (and how they work and are built), but he is interested in studying the stars and really uses the telescope as a tool.
The same holds for the relationship between the computer scientist and the computer. The computer scientists uses the computer to conduct science. Whereas...
