52 MBPS |
The inner part of the wire is made of two conducting element and the outer part is a hollow conductor and the centre part of the cable is made of copper wire. |
The second layer of the coaxial cable is made by coating metallic foil which is used as insulator. |

Two types of Twist Pair Cable are there such as unshielded (UTP) and shielded (STP) cable. UTP wire is composed of copper wire pairs and is covered by an insulated material. STP cable is combined by techniques of noise cancellation, wire twisting and shielding. |
It is a cable used for telephonic voice transmission and connections of most Ethernet in terms of modern. It functions by transmitting data through a pair of wires by making a circuit. It is twisted so that protection can be made against crosstalk to reduce the noise by creating a magnetic field around it. |
$ 30.15 (60m) |
|
Fiber Optic |
100 Mbit/s |
1.6 Tbit/s. |
It is made up of two encased fibres in a separate sheaths with each fibre optical surrounded by a protective layer of a material which is buffer and later a shield of plastic (Kevlar) is layered then finally an outer jack (Kachmar&Kleckowski, 2012). |
It can be used over great distance, security is better as it cannot be tapped; data rate is higher than coaxial and twisted pair and is susceptible to EMI. |
$125 (50m) |

Satellite |
2.56 Tb/s |
100 Gbit/s |
High chance of data loss |
Media installation is not required |
$50 million |
|
Microwave |
100 GHz |
1.0 gigahertz |
The travelling of electrical signals by moving from one node to another over a physical medium is called network media |
The wireless medium operates based on the Microwave, transmitting signals between devices on a LAN |
$63.23 |
|
Radio |
50 GHz |
1.0 gigahertz |
The wireless signals are in the form of electromagnetic waves which can travel even in vacuum or air. |
Transfer data in more ease way rather than wire connection |
$56.25 |
A medium for an electronically noisy factory that should be used to fetch metal is Fibre optic cable because it is immune to electromagnetic interference and it reduces the noise because signals are transmitted in the form of light instead of current. To justify this; fibre optic cable should be used as it has a greater degree of fidelity; works well over greater distances, does not create noise and it is extra secure. The copper wire is sensitive towards acids, waters and chemicals but fibre optic cable has no risk of being damaged by harsher elements. The fibre optical cable consumes less electricity in comparison to copper wire. The electrical conductivity of fibre optic cable is none whereas copper cable has a huge electrical conductivity.
