Consider a network path between a source and destination end systems that consists of one

router. That is the end$-$to$-$end path is end$-$system $->$ router $->$ end$-$system. The source has a file

that is $20,000$ bits long that it needs to transmit to the destination. Assume that all links are $10$

Mbps$,$ propagation delay and router processing delays are negligible and all packets are $10,000$

bits long. You can ignore packet headers. Also assume there is no queuing in the routers.

Determine the time from when the first bit of the file is sent from the source until the last bit is

received by the destination.
