I would wager you also actually own a computer and a processor with an arithmetic logic unit, but I wouldn't assume you know fuсk-all about what it is, what it does, how it works, how it got its name, or why it's significantly different from other parts of the processor with similar functions to warrant a separate designation.
If you have information for me, don't make me beg for it. Just give it to me. I still don't see the difference between a "nice transition" and a "megaphone". Care to elaborate?
