Two nodes $"$A$"$ and $"$B$"$ that are attached at the opposite ends of $1000$ m Ethernet cable. They both have a $1000-$bit frame to send to each other. Both nodes attempt to transmit at t$=0.$ Assume the transmission rate is $10$ Mbps and that CSMA$/$CD is used. After the first collision, node $"$A$"$ will retransmit immediately after it senses the medium is idle. Station $"$B$"$ will retransmit $50\backslash$mu seconds after it senses the medium is idle. Assume that the speed of propagation is $2\backslash$times $10^8$ m $/$ sec$.$ Assume no jamming signal is used. Collision occur at t$=$ sec$.$ Station A will retransmit at t$=$ s e c$.$ The time it will take the frame from $"$A$"$ to be completely delivered to $"$B$"$ is sec$.$ The throughput of node A is bps$.$
