Transmission media is a device which is used to transfer the data between one computer to another computer.There are two types of Transmission media: 1. Guided Media 2. Unguided Media

1 guided, 2 unguided
Guided transmission media means the data signals are guided along the path like cabling system.They dont have any other go they have to pass through the given cable or wire. Guided media are of 4 types : 1. Open wire eg:- Electrical wires from poles. 2. Twisted Pair. 3. Coaxial Cable. 4. Optical Fiber.
In telecom, they are: 1. guided (bounded), ie. Ethernet 2. wireless (or unguided), ie. 2.4GHz In physics there are three: 1. solid 2. liquid 3. gas
There are mainly three types of transmission modes : 1) Simplex : Information can flow only in one direction 2) Half Duplex : Information can flow in both direction but only 1 at a time can send and 1 can receive. 3) Full Duplex : Information can flow in both direction and both can send and rceive at a same time. Transmission media is divided into two : guided (coaxial, twisted pair and fiber optics) and unguided (radio, microwave, infrared).
Here, we have two types of transmission media: 1. Guided media transmission2.unguided media transmissionin guided media,there are wires or cables, whereas in unguided media,different-different waves are used.1. Guided media transmissiona.) co-axial cablesb.) twisted pair cablesc.) optical fiber cables2.) unguided media transmissiona.) infrared rays transmissionb.) radio transmissionc.) microwave transmissiond.) satellite communication transmission
2 types of culture media according to functional type
The Guided Transmission Media is a media which use a "cabling system" that guides the data signals along some specific and explicit path. These data signals are actually bound by the cabling system. This type of media is also called "bound media". Guided media can generically be divided into four types. These are: (1) Open Wire, (2) Twisted Pair, (3) Coaxial Cable and (4) Optical Fiber The first type of guided media - open wire media - is usually describes as an electrical wire that is strung up along the power poles. There is no facility of shielding is provided in this media so noise interferences while communication can not be avoided. So in simple words we can say that it is a path for data signal without any protection from noise interruptions. So this type of media is at risk to a great extent to noise interferences so it is not a good practice to use it for data transmission for more than 20 ft. The second type of guided media is twisted pair in which cables are twisted together in pairs. Each pair consists of a wire for a positive data signal and another wire for negative data signal. The level of noise interference reduction can be determined particularly by the number of turns used per foot. They are inversely proportion to each other. Then the third type of guided media is coaxial cable that consists of two conductors. The outstanding control of the electric resistance characteristics of the cable permit higher data rates to be transferred than twisted pair cable. Finally, there comes Optical Fiber that consists of very thin glass fibers which are capable to carry information at the frequencies in visible light spectrum and even beyond.

In the last two centuries, various types of media have evolved, including print media (newspapers, magazines), broadcast media (radio, television), digital media (internet, social media), and mobile media (smartphones, tablets). These different forms of media have transformed how information is disseminated and consumed by audiences around the world.
