I understand a lot more about computers now than I did many years ago, but there are still things that come up that I have no idea about. Mark just brought up top level domains in a conversation and I had to ask him what that was. As it turns out .com is a top level domain in a web address.
I do now know that a blue cable is not what makes the internet fast, I still don't know many things. Like how to create a sub domain for my about page so I didn't have to create an entirely new site for it.
