Packet Switching
When data e.g. web pages, emails, instant messages etc are sent across the internet, they are not sent as one big file. Instead, the file is broken up into lots of parts called 'packets'.
The packets are reassembled when they arrive at their destination.
See 'Packet Switching' in the 'What is ....?' section for more detail.
