Hints for writing test answers

Ideas and concepts are inanimate things. They cannot take responsibility for tasks. For example: The physical layer is not "responsible for dealing with bits." Instead say, "The physical-layer protocols define how to encode bits on the medium of transmission." The previous sentence specifies knowledge. The first quoted phrase communicates ignorance of the relationship between the physical layer and bits. Avoid phrases such as, "deals with" and "like" as these phrases communicate to me that you don't know what you are talking about.

One of the test questions I have asked, in the past, directs students to list the Internet layers in order and state the layer's purpose, the protocols we studied for that layer, and the services the layer provides. I give a model answer for the Physical and Link layers below.

  1. Physical Layer
    1. The purpose of the physical layer is to represent bits in the medium of that physical layer.
    2. Protocol: Manchester Encoding
    3. This layer provides the service that encodes the bits in a Frame into a physical form suitable for the transmission medium.
  2. (Data) Link Layer
    1. The purpose of the Link layer is to move a packet of bits called a frame across a single link
    2. Protocol: Ethernet 802.3, and MAC protocols CSMA/CD and ARP
    3. This layer provides the following services: framing (of datagrams), link access and unreliable deliver of the frame across the link

As you can see the text above succinctly answers the question without droning on and on about analogies and details that the question does not ask for. LEARN TO WRITE ANSWERS LIKE THIS AND I GUARANTEE YOUR TEACHERS WILL LOVE GRADING YOUR PAPERS!
