As a beginner, you'll find you'll learn more, and learn it better, if you find out how to do such things yourself.
So, try your relevant manuals. Try a search with google, whatever. Get to understand as much as you can. If you don't get it all, come back with the particular parts you don't understand.
Remember that not everything on the internet is correct. Stuff in manuals is. Stuff in manuals on the internet is. For a beginner, understanding manuals can be a bit of a grind, because they assume that the strict terms which are used are understood by the reader. So, colleagues, internet, other manuals, etc can help you understand.
Once you crack the techniques for reading manuals, you've made a big step, so it is worth the effort. The manual is right, the other stuff on the internet can be right or wrong, but either way may help you to understand. Sometimes the less worthy stuff will drive you astray, so look at quite a bit of stuff and see those which are in general agreement as more likely to be right. Remember, the manual is right. All the other stuff is about understanding the manual. Once you understand the manual, there you can with certainty do the "layman" bit yourself.
