2.7.46 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
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!
