Read the first 7 Internet Architecture flashcards as text

  1. Which layer of the TCP/IP model is responsible for physical transmission of bits over a medium like Ethernet cable or Wi-Fi?

    Answer: Network access (link) layer

    The network access layer handles the physical and data-link aspects: transmitting raw bits over the physical medium.

  2. What is 'net neutrality' and why is it relevant to internet architecture?

    Answer: The principle that ISPs should treat all data packets equally without prioritizing certain content or sources

    Net neutrality holds that ISPs must not discriminate between different types of internet traffic or charge differently based on content.

  3. What is a CDN (Content Delivery Network) and how does it improve internet performance?

    Answer: A CDN stores copies of content on servers distributed globally so users retrieve data from a nearby server

    CDNs cache content on geographically distributed servers, reducing latency by serving users from a nearby location.

  4. A router receives a packet destined for 10.0.0.5 but its routing table has no specific entry for that address. What does it typically do?

    Answer: Forwards the packet to a default gateway for further routing

    When no specific route matches, a router forwards the packet to its default gateway, which attempts to route it further.

  5. What distinguishes a 'peer-to-peer' (P2P) network from a 'client-server' network?

    Answer: In P2P, each device can act as both client and server; in client-server, roles are fixed

    In P2P networks, every node can both request and provide resources, unlike client-server where roles are specialized.

  6. Why is the internet described as using an 'open standards' approach, and what is one benefit of this?

    Answer: Open standards are publicly documented protocols that any vendor can implement, enabling interoperability between different systems

    Open standards like TCP/IP are freely available specifications, allowing any device or software from any vendor to interoperate on the internet.

  7. Which organization is primarily responsible for coordinating global internet IP address allocation and DNS root zone management?

    Answer: ICANN (Internet Corporation for Assigned Names and Numbers)

    ICANN oversees the allocation of IP addresses (via RIRs) and manages the DNS root zone to keep the internet's naming system consistent.
