How wide is a bit on a 1Gbps link How long is a bit in coppe

How ‘wide’ is a bit on a 1Gbps link? How long is a bit in copper wire, where the speed of propagation is 2.3x108 m/s?

Solution

Answer :

In 2GB/sec link ,

1 bit will be of 1/2,000,000,000 seconds = .5 x 10^-9 seconds.

It will be .5 x 10^-9 x 2.3 x 10^8 = 11.5 x 10^-1 mlong
