You want to send or upload a video to youtube, or send a photo to Facebook?
It sends within minutes, how does it actually work?
Well the picture divides into packets. Try this: Go to google and find a picture and watch it load up You will see how fast the packets are sent. The packets hop from different networks.
For example is you want to upload a picture to Facebook from your own computer it will split into packets and each of the packets will find there own way to get to Facbook, So maybe packet one will start from your own computer and go to ICHK which leads to PCCW which leads to Optus which leads to Facebook.
Each packet tries to find the quickest route to get to the site you wanted.
After all the packets hop to the website (they might not be in order) they rearrange themselves, In the order that they were first sent in.
Well Done ! You have uploaded your photo!
