Packet Switching
In the packet switching network type on specific path is used for data transfer. Instead the data is chopped up into small pieces called packed and sent over the network. We can route combine or fragment the packets as required to get them to their eventual destination. One the receiving end the process is reversed the data is read from the packets and reassembled to form the original data. A packet switched network is more analogous to the postal system that if is to the telephone system through the comparison is not perfect. An example is shown in figure
