Well I did a simple search on just one of the words in your subject "definitions".
I only searched 4 forums (the ones most likely), off-topic, general, home and pro and virus and worms forums.
That returned 50 hits (and that I believe is a limit of the search settings or in your profile), there are probably more, so the information is out there, it's just learning how to use the tools. Now not all of those posts will be relevant, but there are many which are.
If you are going to post, you choose a subject for your thread/message query; try using some of the wording in your subject (not all of them). This is after all what you are seeking help with.
Try a search using similar wording. Be general (as I did with definitions) at first and if that returns too much information, you can narrow your search by adding additional words.
