Definition
| in 1957 the internet was developed as a reaction to the soviet launch of sputnik. The us government funded the agency ARPA (how can we communicate if a link goes down?) this was the question asked because in 1957 communication networks used a chained point to point approach.

| Transmission layer breaks up our messages into smaller "packets". Each packet is then addressed and and transmitted. when all of the packets are received at their final destination, the transmission layer reassembles these "packets" according to the protocol used by the sender. A transmission layer is applied to each packet including: where it came from, where its going, total number of packets in the full message, size of this packet, protocol type-verification checks. |
