Now that the packet has arrived the web server opens it and reads your computer's request, in this case 'please send me this image'.

Images are often quite large so they need to be split up into lots of packets, often hundreds or thousands of them. All of these packets include information about how they should be put back together as well as where they are going and where they came from.

Different routes

The web server sends these packets back to your computer and once again routers and switches direct them.

The routers try to find the fastest possible route for each packet. They might take different routes and might not arrive in the same order they were sent.

Putting the packets back together

Now that all the packets have been received the information attached to them tells your computer how to put them back together and the image will display on your screen.

This whole process of sending a request and receiving the packets usually takes less than a second!
