Packet Switching in Networking

In Packet Switching, the sender breaks the whole message into a number of packets of suitable length and consisting sequential packet numbers. No dedicated path is established between the two end parties prior to data communication. Packet Switching
The sender sends packets to the next node sequentially. Each node after receiving a packet decides the next route for the packet, the routing decision is done by a node in the path before sending every packet. All the packets are independent in nature and it may traverse different paths to reach the destination. So, the packet may reach the destination in a jumbled fashion. It is the responsibility of the receiver to rearrange the packets according to their sequence number.
