transmission media
Transmission media refers to the means through which data or information is transmitted from one device to another. It is the physical pathway that carries the signals between the sender and receiver in a communication system. There are several types of transmission media, including:
1. Wired transmission media: These include copper cables, such as twisted pair cables and coaxial cables, as well as fiber optic cables. Wired media offer reliable and high-speed data transmission.
2. Wireless transmission media: These include electromagnetic waves, such as radio waves, microwaves, and infrared. Wireless media allow for flexible and mobile communication but can be susceptible to interference and have limited range.
3. Guided transmission media: These are transmission media that use physical cables to guide and contain the signals, such as twisted pair cables, coaxial cables, and fiber optic cables.
4. Unguided transmission media: These are transmission media that propagate signals through the air or space without any physical guide or containment, such as radio waves, microwaves, and infrared.
The choice of transmission media depends on factors such as data rate requirements, distance of transmission, cost, reliability, and environmental conditions. Different types of transmission media can be used in combination to create a communication network.
