Randall seems to be saying that a startup doesn't need to create a new computer system to service their customers, all they have to do is put up a Facebook page which uses Google to find products and then has Amazon deliver them. The middle layer "Transport" is a joke because Amazon literally ships physical boxes, but the OSI model is not about actual boxes; it's about information and the way the information is presented to the user vs what goes on behind the scenes.

But I don't get the part about the horcruxes. Is it just the fact that there are seven of them? Or is there some subtle connection I'm missing here? [[Special:Contributions/162.158.106.180|162.158.106.180]] 05:50, 30 January 2019 (UTC)

: 'Transport' has nothing to do with Amazon, in this case, though the juxtaposition is amusing; also, the networking model has nothing to do with the user interface. The seven layers are from the 'standard' [https://en.wikipedia.org/wiki/OSI_model OSI networking model], which was introduced in the late 1970s to describe how networking systems work (or were expected to at the time). In practice, the [https://en.wikipedia.org/wiki/Internet_protocol_suite#Key_architectural_principles Internet Protocol Suite] model is used, which has more or less the same ideas despite evolving separately, though with only four formal layers (Link, Internet, Transport, and Application) instead of seven (Physical, Data Link, Network, Transport, Session, Presentation, and Application).

:In the OSI model, the Transport layer is Layer 4 (going up from the lowest level, Physical) and represents the part responsible for checking the consistency of data delivery - that is to say, it decides whether or not to check for dropped packets, and whether to resend dropped ones. In the actual Internet model, the rough equivalent is the [https://en.wikipedia.org/wiki/Transmission_Control_Protocol Transmission Control Protocol] (for 'connected' transmissions which do check and resend) and [https://en.wikipedia.org/wiki/User_Datagram_Protocol User Datagram Protocol] (for 'connectionless' ones which don't).  [[Special:Contributions/172.68.78.10|172.68.78.10]] 16:29, 30 January 2019 (UTC)
