3.7.46 Types Tutorial Exercise 14

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 ns / ns     1:  0.81356
     2:  4.1 ns            .                       .
         .

       ' 4.1 ns <RET>        /                       u s

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!
