  1. In theory, a network communication could be sent as one continuous stream of 1’s and 0’s.  A better approach is called:
    1. Compression
    1. Segmentation
    1. Multi-address
    1. Attenuation
  2. Segmentation improves the reliability of a network.  Which of the following best describes those improvements?
    1. Separate pieces of each message can travel across different paths to a destination.
    1. If a path fails or becomes congested, an alternate path can be used.
    1. If part of the message fails to make it to the destination, only the missing parts need to be retransmitted.
    1. All of the above.
  3. A group of computers are connected in a multi-story building. This would be considered what type of network?
    1. LAN
    1. MAN
    1. SAN
    1. WAN
  4. A group of computers in Vancouver are connected to another group of computers in Windsor. This would be considered what type of network?
    1. LAN
    1. MAN
    1. SAN
    1. WAN
  5. Of the following list, which items are governed by protocols?
    1. The format of the message.
    1. The method by which networking devices share information.
    1. The setup of data transfer sessions.
    1. All of the above.
  6. Which of the following statements are true? (Choose Two.)
    1. A protocol suite cannot function without a set of standards.
    1. Each protocol involved in a transmission works alone with no dependency on other protocols in the suite.
    1. The sending of error or status messages is a function exclusive to the network hardware.
    1. Protocols describe what is to be done to communicate,
  7. One of the TCP/IP model layers provides the operating environment for drivers for software applications, modems and other devices.  Which one is it?
    1. Internet
    1. Network Access
    1. Transport
    2. Application

    1. Switch
    1. PDA
    1. IP telephone
    1. Hub
    1. Printer
  2. Which layer of the TCP/IP model performs the function of the Network Layer in the OSI Model?
    1. Internet
    1. Network Access
    1. Transport
    1. Application
  3. A purpose of the OSI model is to provide which of the following?
    1. A standard for the software/networking industry.
    1. A standard for the hardware/networking industry.
    1. A reference for network users and administrators.
    1. All of the above
  4. Using the number beside the layer name as your answer, match the layer of the TCP/IP Reference Model to the description of the layer’s function.

A. Supports communications among devices
across diverse networks. 		1. Application
B. Controls the hardware devices and media. 2 Transport
C Represents data to the user plus encoding
a dialog control. 		3 Internet
D Determines the best path through the
network. 		4. Network Access
