What are the two main types of transmission media?

The two main types of transmission media are wired and wireless. Wired transmission media involves physical connections, such as copper cables or fiber optic cables, where data travels through a medium that is enclosed or connected. This medium allows for high-speed and reliable data transmission over long distances. On the other hand, wireless transmission media utilizes electromagnetic waves to transmit data without physical connections. This includes technologies such as radio waves, microwaves, and infrared signals, allowing for mobility and flexibility in various applications.

This classification into wired and wireless reflects the fundamental ways in which data is transmitted, emphasizing the nature of the connections and the methods of communication used. Understanding these two categories helps in grasping how different communication systems operate, each having its advantages and specific use cases that cater to varying networking needs.
