Step by step
Solved in 2 steps
- TDM, FDM, and CDM are all multiplexing techniques used at the physical layer.What are the upsides and downsides of each approach, please?How does "full duplex" communication at the Physical Layer enhance data transfer rates compared to "half duplex"?The physical layer utilises three distinct methods for multiplexing, namely TDM, FDM, and CDM.What are the advantages and disadvantages associated with each strategy?
- How does the "Physical Layer" handle signal modulation and demodulation?Discuss the concept of multiplexing in the context of transmission media. How does it enable the transmission of multiple data streams over a single medium, and what are the key techniques used?How does the choice of cable and its length affect signal attenuation and data loss in high-speed data transmission, especially in the context of 10Gbps and 40Gbps networks?
- How does the concept of "bandwidth" relate to the data-carrying capacity of different transmission media?Explain multiplexing and demultiplexing used in data communication. How do they work and in which OSI layers are they used? (max of 5 lines)Discuss the concept of bandwidth in the context of transmission media. How does bandwidth affect the data transmission capacity of a medium?
