How long will it take for a signal to get from one end of the computer to the other?
1: m / c 1: 3.3356 ns
. .
' 1 m / c RET u c ns RET
(Recall, ‘c’ is a “unit” corresponding to the speed of light.)
1: 3.3356 ns 1: 0.81356
2: 4.1 ns .
.
' 4.1 ns RET /
Thus a signal could take up to 81 percent of a clock cycle just to go from one place to another inside the computer, assuming the signal could actually attain the full speed of light. Pretty tight!
