Final answer:
To meet global performance and traffic needs in communication media, it's vital to consider factors such as throughput (actual data transmission rate), bit rate (raw network capacity), robustness (network's ability to handle difficult conditions), and range (effective operating physical distance).
Step-by-step explanation:
When determining the best communication media to meet global performance and traffic needs, several factors must be considered to ensure effective and efficient communication. One crucial factor to consider is the throughput, which is the actual amount of data successfully transmitted over a communication channel in a given amount of time. This considers the capacity of the channel and the data rate after accounting for network overhead, errors, and retransmission.
Another key factor is bit rate, the number of bits that can be transmitted over a network in a specified amount of time. While bit rate gives a raw measure of network capacity, it does not account for potential losses or errors in transmission.
Robustness is also essential, referring to the network's ability to handle various conditions such as interference, noise, and high traffic without losing data integrity. Lastly, range is the physical distance over which the communication media can effectively operate without significant signal degradation.
