GATE CSE 2015 Set 3 | Question: 36
Two hosts are connected via a packet switch with $10^7$ bits per second links. Each link has a propagation delay of $20$ microseconds. The switch begins forwarding a packet $35$ microseconds after it receives the same. If $10000$ bits of ... between the transmission of the first bit of data and the reception of the last bit of the data in microseconds is ______.
