Packet Switching Vs Circuit Switching Packet-switched and circuit-switched networks use two different technologies for sending messages and data from one point to another. Each have their advantages and disadvantages depending on what you are trying to do. Packet Switching: In packet-based networks, the message gets broken into small data packets. These packets are sent out from the computer and they travel around the network seeking out the most efficient route to travel as circuits become available. This does not necessarily mean that they seek out the shortest route. Each packet may go a different route from the others. Each packet is sent with a ‘header address’. This tells it where its final destination is, so it knows where to go. The header address also describes the sequence for reassembly at the destination computer so that the packets are put back into the correct order. One packet also contains details of how many packets should be arriving so that the recipient computer knows if one packet has failed to turn up. If a packet fails to arrive, the recipient computer sends a message back to the
