What are all the different types of transmission of media that can be used to connect to the Internet?
What are the types of Transmission media ?
Hi,
The signals  are usually  carried  over  transmission media which are classified in to two types :
-
Guided Media – The guided media that provides a media of carrying signals or in general terms, it acts as a conduit from  one media  device to other which includes a  twisted-pair fiber optic cable and co-axial  cable. A signal  which is traveling along these kind of media is directed towards the target where it is supposed to carry it follows a guided path and it transfers all the signals to that path which is specified . The transmission which is of guided media uses the co-axial or fiber optic cables for the transport of signals these cables are carry the signals in electrical current formÂ
Ex is Wired network ,Land line phonesÂ
-
Unguided Media – This is the wireless media that transports the electromagnetic waves without any physical medium the signals in this type of media are target is specified. The unguided media is now a days widely used the best example for unguided media is a wireless network .The packets here can be used by any authorized person. This kind of media uses the signals of satellites or any radio signals for carrying of signals.
What are the types of Transmission media ?
The process by which data is transformed or changed from one place to another is referred to as transmission or sometimes communication media. There are two categories by which transmission media is used within computer communications: the Bounded or Guided Media and the Unbounded or Unguided Media. In Bounded Media, these are the physical links through which signals are contained.
That’s why it is also called Guide Media, the flow or transmission of the media is somewhat guided by the physical link which is restricted to a narrow path. Bounded media are composed of an external conductor which is normally made of copper enclosed by a jacket material. Bounded media are great because they offer different advantages like high speed, excellent security, and especially low cost.
But there are times this type can’t be used mainly because of great distances and that’s the main disadvantage of using this media. There are three common types of bounded media used in data transmission: coaxial cable, twisted pairs cable, and fiber optics cable. See image for example.
The coaxial cable is the very common and widely used communication media. One example is the antenna cable connecting the TV to the outdoor antenna; it is made of coaxial cable. The Unbounded or Unguided Media, on the other hand, are the ones used in wireless connections where transmission and reception are accomplished using an antenna.
