the difference between comp. engg and cmp. sc. and engg.

In renowned computer scientist Edsger Dijkstra words "Computer science is no more about computers than astronomy is about telescopes." The design and deployment of computers and computer systems is generally considered the province of disciplines other than computer science. So despite its name, a significant amount of computer science does not involve the study of computers themselves. Instead Computer science is considered to have a much closer relationship with mathematics than computers.

Whereas the study of computer hardware is usually considered part of computer engineering, while the study of commercial computer systems and their deployment is often called information technology or information systems.

Computer Engineering encompasses broad areas of both Electronics engineering and computer science. Computer engineers are engineers who have training in the areas of software design and hardware-software integration.
