In theory, doesn't electricity travel at the speed of light? 186,000 feet per second, I think.
I once read theory that electricity flows through copper more efficiently than light flows through fiber, so the electrical bits would arrive first in a race. I have both interfaces here in the lab... I'll time it this afternoon... (just kidding).

[7:41192] Ok I have spent ages trying to find an answer to this question, and probably only added to my confusion. You know how it is you spend ages looking at something and become snow blind or get tunnel vision or whatever, but I cannot see the answer to the following: How far does a bit travel in say 1 second or put another way how long does a bit take to travel a certain distance ? I understand, or think I do that if the line is say 128kbps then I can, in theory at least, expect 128,000 (approx) bits start down that line every second. But how long do they take to reach the other end, assuming a point to point link and both ends being the same speed, obviously. There has to be a nice simple formula for this somewhere, you know the sort of thing x= line speed, y = distance z = time etc Any ideas or poitners would be appreciated Thanks Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=41198&t=41192 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
