Define the term "transmission media."

Transmission media refers to the physical pathways through which data is transmitted from one device to another in a network. This can include cables, wires, fiber optics, and wireless communication technologies. Transmission media play a crucial role in the speed, reliability, and efficiency of data transmission in a network.

Transmission Media

Transmission media refers to the physical pathways or channels through which data and signals are transmitted from one point to another in a communication system. It serves as the carrier of information between devices, allowing data exchange over a network or between two or more devices.

Transmission media can be categorized into two primary types:

- Guided Media: Signals travel along a physical, dedicated path, such as:
- Optical fiber
- Coaxial cable
- Twisted-pair cable

- Unguided Media: Signals are transmitted through the environment without the use of a physical path, such as:
- Wireless (radio waves)
- Satellite
- Microwaves

The choice of transmission media depends on several factors, including:

- Data rate and bandwidth requirements
- Distance between devices
- Cost
- Reliability and security
- Environmental conditions

Transmission media plays a critical role in communication systems by ensuring efficient and reliable data transmission and reception. They enable the transfer of information between devices, facilitating connectivity and the seamless exchange of data.
