One of the challenges we face as educators is that we work not just in a field of acronyms, but in a discipline where the definitions themselves seem to undergo subtle changes over time. As a result, we sometimes may be using the same words as someone else, but meaning something a bit different.
In the interest of clarity, it might be helpful to see how Wikipedia defines the core areas that often fall under computer science. Take a look at the definitions below and see how well they match your own definitions.
