Computing is part of everything we do from the cars we drive, to the movies we watch, to the ways businesses and governments deal with us. Understanding different dimensions of computing is part of the necessary skill set for an educated person in the 21st century. Whether you want to be a scientist, develop the latest killer application, or just know what it really means when someone says “the computer made a mistake”, studying computing will provide you with valuable knowledge. You will be able to solve complex, challenging problems and make a positive difference in the world because computing drives innovation in the sciences (human genome project, AIDS vaccine research, environmental monitoring and protection), and also in engineering, business, entertainment and education.
