Network Architecture (Back to all quizzes)

  1. Why do engineers use a "model" to organize their approach to solving a large and complex problem?

    Because it allows them to build something small and test it in a wind tunnel
    Because talking about a model delays the actual start of the hard work
    Because they can break a problem down into a set of smaller problems that can be solved independently
    Because it helps in developing marketing materials

  2. Which is the top layer of the network model used by TCP/IP networks?


  3. Which of the layers concerns itself with getting a packet of data across a single physical connection?


  4. What does CSMA/CD stand for?

    Carrier Sense Multiple Access with Collision Detection
    Collision Sense Media Access with Continuous Direction
    Correlated Space Media Allocation with Constant Division
    Constant State Multiple Address Channel Divison

  5. What is the goal of the Internetwork layer?

    Insure that no data is lost while enroute
    Get a packet of data moved across multiple networks from its source to its destination
    Make sure that only logged-in users can use the Internet
    Insure than WiFi is fairly shared across multiple computers

  6. In addition to the data, source, and destination addresses, what else is needed to make sure that a message can be reassembled when it reaches its destination?

    An offset of where the packet belongs relative to the beginning of the message
    A location to send the data to if the destination computer is down
    A compressed and uncompressed version of the data in the packet
    The GPS coordinates of the destination computer

  7. What is "window size"?

    The sum of the length and width of a packet
    The maximum size of a single packet
    The maximum number of packets that can make up a message
    The maximum amount of data a computer can send before receiving an acknowledgement

  8. In a typical networked client/server application, where does the client application run?

    On your laptop, desktop, or mobile computer
    On a wireless access point
    On the closest router
    In an undersea fiber optic cable

  9. What does URL stand for?

    Universal Routing Linkage
    Uniform Retransmission Logic
    Uniform Resource Locator
    Unified Recovery List
