|
|
Transmission media is a communication channel that carries the information from the sender to the receiver.
|
|
|
Transmission media can be a computer, server, tablet, and mobile phone.

|
In a fiber-based network, the bits in the form of light pulses.

Detailed explanation-1: -They are coaxial cable, twisted-pair, satellite, fiber optics & microwave, Thus, this is all about transmission media and there are some factors that are considered when choosing a transmission Medium like rate of transmission, cost, simple installation, and distances.
Detailed explanation-2: -There are two Types of Transmission Media i.e., guided media and unguided media. In guided media, the transmission signal properties are controlled and focused in a fixed constricted channel, which can be implemented with the help of physiologically connected contacts.
Detailed explanation-3: -Examples of this include microwave, radio or infrared. Unguided media provide a means for transmitting electromagnetic waves but do not guide them; examples are propagation through air, vacuum and seawater.
