TRANSMISSION MODES IN NETWORKING

TRANSMISSION MODES IN NETWORKING:

There are two types of transmission modes one of them is the guided transmission mode and the another is non-guided transmission mode. The guided transmission mode is further divided into three types they are:

  1. Twisted Pair cable
  2. co-axial cable
  3. optical cable
similarly, The non-guided transmission mode is also further divided into three types they are:

  1. Radio-Waves
  2. Micro-Waves
  3. Infra-rared Waves



Guided:

In guided transmission medium the systems are connected through a physical wires like wlan cables, dish wires etc.

  • Twisted Pair Cable:
          In twisted pair cable there will be two wires which are twisted. Generally these cables           are made of copper which are surrounded by an insulating material. The twisted Pair             cables are further divided into two types:
  • Shielded twisted pair cable
  • unshielded twisted pair cable
         In shielded Twisted pair cable the copper wires are provided with extra insulation or             plastic coating which provides the strength to the overall structure these are having             higher bandwidth compared to unshielded twisted pair and these cables generally                 travel underground . It also reduces the noise and the signal interferences Whereas in             unshielded Twisted pair no extra insulation is provided so these are easy to install but          less secure and also has low bandwidth.
