Unfortunately I don't remember where I read this, but I've once read somewhere that Apple refuses to use nvidia gpus because nvidia doesn't give Apple access to the driver source code. AMD on the other hand does.

IP is a network layer protocol, it connects two hosts. TCP is a transport layer protocol, it connects two processes and runs on top of a network layer such as IP. The link layer connects two links (e.g. your computer and your WiFi router), examples are Ethernet or 802.11 (even though they also incorporate management of the physical layer).

What the satellites have to deal with is pysical/link level protocol to send packets from one to another (and from and to ground stations) as well as a network level protocol to route traffic inside the SpaceX network.

Concerning Snap, you are right in terms of market cap that generated evan spiegel billions. But don't mix that with profits.

    How could Snapchat possibly make money?

They never did, and they probably never will (they even acknowledge this in their IPO filing).

Because it's a fullstack framework.
