Transmission Media

Watch this video from 37:08 to 58:00. Focus on the three common guided media for data transmission: twisted pair, coaxial cable, and optical fiber. Note their key characteristics and applications. Consider the advantages and disadvantages of each medium in terms of data rates and distances they can cover. Think about when it might be more practical to use twisted pair for shorter distances, coaxial cable for medium distances, or optical fiber for long-distance, high-speed connections. Be able to identify the main differences between these media. What are some real-world scenarios where you might choose one over the others?
