Site: Howstuffworks

I found this site again the other day when I wanted to see if my understanding of how DNS (Domain Name Services - how typing www.google.com works behind the scenes) works was correct. The site has a very good overview of how many things work.
Looking further in the electronics section they talk about
Home Networking
I was reading through one of the sections on CDs - and it was interesting how some of the data was obviously dated: they were talking about 2x burners as a premium finally falling below the $1000 range.
I was surprised that in talking about CD Tracking they didn't mention that a CD drive actually has 5 read 'heads' - 1 for data and 4 for positioning. Perhaps it is hidden in one of their later articles.
