Calculate the latency (from first bit sent to last bit received) for: (a) 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. (b) Same as (a) but with three switches.

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is…
