Best Answer

a bit that goes along a network cable of say 1GB. the Gigabit speed is about 400MHZ,

f=1/t

so, t=1/f

therefore, t=1/400 x10^6

t=0.0025 x 10^-6

now, s=vt

electrons travel at almost the speed of light i.e. 299 792 458 m/s

thus, s= 0.0025 x 10^-6 x 299 792 458 = 0.75 metre.

please note 400MHZ could, due to cycles provide 2 bits not 1, so length of 1 bit will be

more like 0.3 metre.

i might be wrong with numbers but think idea is correct.
