What is Packet Switching
Files are broken up into packets, each packet is numbered in order, so they can be reassembled in correct order at their destination.

What do we need in Packets in order for them to work?
1) Address of where packet is from, 2) Address packet is going to, 3) Length of packet, 4) number of packet in sequence of file. Packets have a Head and Tail to indicate where they start and end.

Name 3 Advantages of Packet Switching
1) Damanged or lost packets are easily identified and re-sent by identifying number/sending copy. 2) Packets on the Internet are sent via different routes so harder to intercept. 3) Networks are not tied up by blocking up channels like Circuit Switch
