Network Topology
Packet switching
- you want to email a photo, first it is broken down into small packets of data Each packet is then given a header which contains the IP address of the network and device that it is being sent to. It also contains the IP address of the network that it was sent from
- The header also contains the packet number as well as the total number of packets, for example packet 4 of 60, packet 45 of 60. When the packets arrive at the destination this information is used to reassemble the data. Packets can be lost so sometimes the computer request the packet to be sent again, if a packet never arrives then it is deleted by the route
