According to the given figure, assume that, PC0 wants to send a message to PC4. If the distance between the two points is 22,000 km, 3.2-kbyte message sends in 2.4 x 100000000 mls speed through cable and the transmission link has 1.5 Gbps Bandwidth. When the message arrives at Routers , Router0 already has 4 packets to process in the queue and each will need 2ms. Router1 has no packets in the queue, but if it had then would require 3ms to process. Router2 already has 5 packets to process in the queue and each will need 1ms. Calculate the total time to send the message from PC0 to PC4.

Network transmission cabling

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 known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
