Calculate the latency $($from the first bit sent to the last bit received$)$ for $1$ Gbps Ethernet with a single store$-$and$-$forward switch in the path, and a packet size of $5000$ bits. Assume that each link introduces a propagation delay of $10$ us and that the switch begins retransmitting immediately after it has finished receiving the packet.

Ans: The transmit delay $=5000/1$ Gbps $=$ Blank $1$ ps

The total transfer delay $=$ Blank $2*($transmit delay $+$ propagation delay$)=$ Blank $3$ ps
