1. An important aspect of an Application Layer protocol like HTTP is that it is responsible for the formatting, coordination and error control of messages sent between applications. It provides a set of rules that applications use to communicate over a network.

2. The IP address for a domain like www.dr-chuck.com can be found by using a DNS (Domain Name System) lookup. This is a protocol within the set of standards for how computers exchange data on the internet and on many private networks. The IP address can change over time and is not static.

3. The amount of memory a server needs to serve requests depends on the volume and complexity of the requests. More complex and numerous requests require more memory. However, it's not just about the memory, the server's processor and network connection also play a significant role.

4. In the client-server model, the client application initiates the conversation. The client sends a request to the server, and the server responds to the client's request.

5. The time we wait before packets are retransmitted depends on the protocol being used. In TCP (Transmission Control Protocol), for example, this is dynamically determined based on the estimated round-trip time between the sender and receiver. If an acknowledgement of receipt is not received within the expected timeframe, the packet is retransmitted.
