Answer 1

So look the term up on the Internet. Read a few of the entries, until you get the sense of it. If there are terms used which you don't recognize, then look them up, too. Probably everyone in your class is doing the same. Fortunately, this is not a type of resource for which you must compete (and resource utilization overlap is exactly the idea you're learning about)!
