Did you know that every image you send, document you write or video you see has to be sent across to you in packets? We looked at packets in our recent Computing lesson and learnt that packets are when documents online are broken up into lots of pieces and sent across the internet to the receiver. It is a bit like a letter – the packet is sent from one IP address (a bit like a postcode) to another and each packet can travel a different way, although they will all end up at the same place! We created our own puzzles to demonstrate how a picture can be broken up and reassembled once it has reached the recipient.
