Question

Write down the process for transferring data on the internet

Answer 1

1) The data is broken up into bits of same sized pieces called packets. 2) A header is added to each packet explaining where the data has come from, where it should end up and where it fits in with the rest of packets. 3) Each packet is sent from computer to computer until it reaches its destination. Each computer on the way decides where next to send the packet. All packets may not take the same route as the other. 4) At the destination, the packets are examined. If any packet is missing or damaged then a message is sent asking for the sender to send the message them again. 5)The packets are now reassembled into their original form.
