MAC OS X, now we're talkin'

Ok, so this article was a little better. I still had to look up several terms but after the LINUX article, I was ready (more or less). I have used the MAC OS X, so I was sort of familiar with some of the jargon. I am pleased to say that I remembered what "firmware" was and I was all over the discussion on "booting." I am also familiar with the use of LDAP as that was how we authenticated at the library where I was once employed. Is this progress, on the road to computing/technology mavenship...God, I hope so. I did learn about the term "Open Source" which seems to me to be a fabulous way to share information and allow broader access to operating systems that are customizable...is that a word?!
