Question

A LAN operates Ethernet with CSMA/CD mechanism runs at a transmission rate of 8 Mbps and one way signal propagation time is 25 microsecond, the  minimum transmitted frame length is ________ bits

Answer 1

To detect collision time , we need to have Fram Length >= 2*Tp*B

L>=2*25*10^-6*8*10^6
L>=400

So , Answer is 400 bits we need to have minimum to transfer
