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                               

In a packet  switched network no circuit  is set up prior to sending  data  between  devices. Blocks of data even from  same file or communication may  take  any  number  of paths  as they journey  from one device to another.
