Answer 1

It's related with mp3. The biggest difference was, mp3 only deals with audio, while mpeg deals with audio and also video. Another difference is that mp3 is just a portion of the standard mpeg.
The use of mpeg still widespread while mp3 would been superseded.

Meanwhile, this isn't an ignorant question. Everyone is free to ask when they're don't know.

Cheers.

Answer 2

That's definitly not an ignorant question. This subject is very complicated, at least for me. Mpeg and ogg are so called containers. The best thing to do if you want a deaper understanding is to read articles and wikis about media types, formats, containers, codecs etc..
