Assignment: There is a common misconception that analog technology is no longer used in the transmission of digital data. However, analog transmission of data is transmitted using electricity, light, and radio. Transmissions in the air use radio, microwave, and satellite media. These transmissions take place in a specific OSI layer.

Choose one of the following:

Option 1:

Create a detailed diagram or set of diagrams to show how the letter A is transmitted in an electrical, light, and radio wave. Show the similarities and differences between how data is transmitted in these three processes. Show the layers of the OSI model that are involved with translating the A to wave form or light pulses to include coding. Annotate the diagram(s) or add written information to the diagram(s) to explain the processes to a person that is not familiar with the technology.

Option 2:

Write a 1000 word paper explaining how each of the following protocols work to transmit data over a network: Ethernet (electric), FDDI, Fiber Optic (light), and WiFi (radio waves).
