the problem of course with a definition like computer related science and technology is that computers play an increasingly important role in practically all of science and technology these days whatever form the definition eventually takes i think the core difference to get across is that computer science is that science which is about computers and not merely involving or facilitated by the use of computers in other words it should be clear that fields like bioinformatics systems theory and computational physics are not computer science even though they rely on computers and even contribute knowledge back to computer science sometimes
