In this video you'll learn how the internet works by following a real message under the sea to France. By following its journey, you'll finally understand terms like 'IP address', 'packet', and 'router', but most importantly you'll appreciate the remarkable technology that enables the internet to function reliably 24/7.

00:02 Undersea cables enable global communication 01:33 Understanding how messages cross the internet 03:04 How multiple computers share the same network connection 04:23 Messages travel through routes using IP addresses. 05:49 Routers forward messages to the public internet for reaching its destination. 07:10 Data travels through the internet in tiny packets 08:37 Packets traverse the internet simultaneously and can be reassembled at the destination. 10:08 Messages are split into packets and routed across the internet using HTTP standards.

Additional info : IP address can either be IPv4 or IPv6. The second approach is the newest version of IP address format.

Additional info 2 : In addition to IP address, a packet also contain a MAC address, which specified which hardware or network interface control (NIC) is destinated to.

Additional info 3 : When we make a request on computer, such as connecting to google, the request will be wrapped in the format required by various protocols in your computer. Then it will past to NIC to make the final wrap before sending it to the next device. When the next device received your packet, it will check for error in your data and unwrapped it to reveal the IP address. After checking out the route table, the data will again be wrapped by NIC with a new sender MAC address before sending it to the next device.

Additional info as well: first cable is usually not a true first leg. There is usually an internal router on the PC to handle multiple MACs transparently without the need to specify outbound hardware to issue a request.
