Coaxial Cable
In early networks coaxial cable was the cable of choice because it was relatively inexpensive, reliable and robust. It consists of:
- A central conductor
- An insulator
- A braided metallic shielding
- An outer jacket
The core of a coaxial cable carries the electronic signals and the braided metallic shielding is used to protect the signal from external noise and crosstalk that could cause interference and possibly corrupt the data. Due to this protection, coaxial cable is more resistant to interference and attenuation than twisted pair cabling.
