Difference between a computer scientist and a computer engineer?

I came across this interesting article when i was reading the May edition of Reader's Digest.
the article can be found on page 37 under section Facts.

Q: What is the difference between a computer scientist and a computer engineer?

Computer scientists are motivated to understand and apply theoretical concepts while engineers are consumed with practical considerations of constructing working systems.

Engineers specialise either as hardware or software experts. AN ATM is a good example of how they collaborate: Software engineers write the programs that process your request to withdraw cash, and hardware engineers build the necessary to perform the transaction. A third group, mechanical engineers, design the machine that physically grabs your bank card.

University of Alberta professor Greg Kondrak illustrates the job of a computer scientist, who concentrates on software. In 1999, while doing doctoral research in computational linguistics, he developed ALINE, a program to identify similar-sounding words in any language. In 2002, when the US Food and Drug Administration was hunting for a way to curb the sometimes fatal confusion that arises when very different drugs are given similar names, Kondrak was contacted. The computer scientist passed along ALINE and made another program that compares the spelling of words. The FDA now uses a blend of both to analyse names proposed for new drugs.

=) hahahahaa, I guess I am now better equipped to answer this kind of question.
