7. Life Without Computers How would you do the following:  Send birthday greetings to a friend in Cleveland?  Find out which movie won the Academy Award for Best Picture in 1993?  Find out your grades for the last semester?  Film a battle between starships?  Research a paper on Apple's A6 processor?  Get IBM's stock price for 1/5/82?

8. Life Without Computers (Answers)  Send birthday greetings to a friend in Cleveland? Phone them or mail them a card  Find out which movie won the Academy Award for Best Picture in 1993? Call your local reference librarian  Find out your grades for the last semester? They were mailed to you (or your parents)  Film a battle between starships? Build scale models and film them  Research a paper on Apple's A6 processor? Go to the library, check journals  Get IBM's stock price for 1/5/82? Ask broker or check at business library

10. What is a Computer? A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. Wikipedia http://en.wikipedia.org/wiki/Computer

11. Assignment Live one day with using computers, directly or indirectly (usage necessary for medical reasons is permitted). How is life different?

12. Computer Science Computer science is the discipline that seeks to build a scientific foundation for such topics as computer design, computer programming, information processing, algorithmic solution of problems, and the algorithmic process itself. It provides the underpinnings for today's computer applications as well as the foundations for tomorrow's computing infrastructure. J. Glenn Brookshear

13. Computer Science Computer science is the study of the theoretical foundations of information and computation. It also includes practical techniques for their implementation and application in computer systems. Computer scientists invent algorithmic processes that create, describe, and transform information and formulate suitable abstractions to design and model complex systems Wikipedia http://en.wikipedia.org/wiki/Computer_science

14. Quote Computer science is no more about computers than astronomy is about telescopes. Edsger Dijkstra

15. This Course Using computers is one thing – understanding how they work is another. Consider the analogy between driving a car and maintaining or repairing a car. This course is for those who wish to know more about computing technology, networking, software, algorithms, and the social aspects of computing: privacy, security, artificial intelligence, and social networking.
