...
What bad things can happen to IP packets and how do these occur?

When creating a server with the BSD socket API, what are the 4 socket system calls that you must issue? Explain what each of these does.
...
Why does the BSD socket API require that all quantities are sent in network byte order?
...
Why does the Internet need congestion control?
...
Why does the BSD socket API define a generic socket address structure?
Because back in the 70's there were many different protocols that it needed to be able to interact with.
Why do we refer to the Internet's architecture as an "hourlgass"?
There are various ways of implementing the lower and higher layers of the Internet architecture, but at the Network layer, everything must pass through the IP protocol.
Explain how the internet is a network of networks.
There exist many intranets where devices are networked together. For the information to go from one local network to another, those networks must also be linked together and able to communicate.
What does it mean to be a Tier-1 or Tier-2 ISP?
Tier-1 provides national/international coverage. Tier-2 provides regional coverage. They sell their connections to Tier-3, which provides local coverage to be purchased by individuals.
Why do the recv() and send() socket operations need to be called in a loop by the application protocol?
To ensure that the entire message is sent/received, since only some of the bytes might be sent in a single call.
What is the internet?
