| Radio | Up to 1 Gbps | Not applicable | High (suitable for long-distance transmissions) | Low to Moderate (vulnerable to interception and jamming) | Up to 100 kilometers |
in general: wired transmission media are higher security because it are more difficult to intercept data transmitted through physical cables as the hacker would need to be physically connected to a network, which would be generally impossible
its much easier to use wireless hacking software programs to intercept wirelessly transmitted signals
Twisted pair → a form of wired transmission media where wires are covered with plastic insulation and twisted in pairs to cancel magnetic fields generated by each wire, thus reducing interference and noise in transmission. Data is transmitted through elecrical pulses in binary form.
Coaxial → a wired transmission medium consisting of a core of copper surrounded by layers of insulation and mesh to reduce noise and interference.
used for cable television and broadband internet due to higher speed
Works by sending electrical pulses in binary form
