It is very low bandwidth and it is easily tapped either physically or by monitoring its electromagnetic radiation
2- Coaxial cable:
It is greater bandwidth than twisted-pair but it is very expensive.
3- optical fibers:
It is very high bandwidth , very high bit rate.
4- Radio (wireless):
It is greatly depending on the particular frequency of the electromagnetic wave
Some of Radio advantages
a- They are very flexible and suitable for all terrain
