Transmission media refers to the physical pathways through which data is transmitted from one point to another. This can include various types of cables, such as fiber optic cables, coaxial cables, and twisted pair cables, as well as wireless methods like radio waves and microwave signals. Each type of transmission media has its own characteristics, affecting speed, distance, and bandwidth. The choice of transmission media is crucial for effective communication in networks. For instance, fiber optic cables offer high-speed data transfer over long distances, while twisted pair cables are commonly used in local area networks (LANs). Understanding these options helps in designing efficient communication systems.
