How do you know when to use ANALOG vs DIGITAL?

Why is "analog" spelled funny sometimes?

Are these different cables than regular old analog/digital cables?

Are the ones with the added "ue" better, or just "funny"?

There are a couple other "funny" spelled words used round here, but I can't think of em right now.

Let me know if I think of em.

I think Sean's answer was excellent.

Dekay: I tend to "favour" the "olde English" spelling variations of several words. Having said that, i typically say "aluminum" even though it was originally called "aluminium" by the English : ) Sean

What is the colour of your favourite aluminium analogue cable catalogue? ;-)

You answers are definatly very scientific, you have the verbal accuracy of a 30-06 with a high powered scope.

Keep yer explanations as they are, mine are dumbed-up enough, it is nice to get an answer that goes more in depth and explains a little more.
