Answer 1

Steps followed while transferring data are 

• The data is broken up into bits of same sized pieces called packets. 
• 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 the packets. Each packet is sent from computer to computer until it finds its destination. 
• Each computer on the way decides where next to send the packet. All packets may not take the same route. 
• At the destination, the packets are examined. If any packets are missing or damaged, a message is sent asking for them to be re-sent. This continues until all packets have been received intact. 
• The packets are now reassembled into their original form.
