Activities/Practicals:
1. Differentiate between OSI and ISO. Also explain any five duties/services of Transport Layer.
2. Assume a data stream is mode of ten 0s, Encode this stream using the following encoding schemes. How many changes (vertical line) can you find for each scheme? Polar NRZ-1, NRZ1, AM1, Manchester.
3. What is the sampling rate for PCM if the frequency ranges from 100 Hz to 400 Hz?
4. Consider the transmission system using frequency Division Multiplexing. What cost factors are involved in adding one more pair of stations to the systems?
5. Draw a network structure established in your study center, define and explain all the nodes, medium, software’s and hubs. Suggest a best solution for the problems identified by your analysis, discuss with your teacher as well.
