| Resources such as printers can be shared across the network. Twenty computers in a room could share one printer over a network. | Prone to receiving external attacks without appropriate network security. |
| You can communicate across the network and often bares no cost. | Specialist technicians will need to be employed to maintain the network against failure. |
| Roaming - Information can be accessed across different geographic sites. | The hardware necessary to build is expensive because there are number of devices necessary. |
| Networks can stream using web applications to computers without the need to download and store the whole software file. | Networks allows for viruses to be easily spread, which can cause wide network failures and damages to files. |
| Fibre Optic | Optical signal (Light) communication through glass fibres, which is economical compared to coaxial and twisted physical media. |
| Fibre Optic | Very low noise contamination |
| Fibre Optic | Not affected by magnetic inference |
| Fibre Optic | High bandwidth meaning large amounts of the data can be downloaded and uploaded. |
| Fibre Optic | Disadvantage: Difficult installation |
| Twisted Pair | Disadvantage: Electrical signal communication through wires. This is not energy efficient. |
| Twisted Pair | Bit o both: Medium noise contamination |
| Twisted Pair | Bit o both: Medium noise contamination |
| Twisted Pair | Less affected by external magnetic interference. |
| Twisted Pair | Bit o both: Medium bandwidth meaning a moderate amount of data can be downloaded and uploaded. |
| Twisted Pair | Reasonable easily installation. |
| Twisted Pair | Disadvantage: Moderately expensive compared to coaxial cables. |
| Coxial | Disadvantage: Electrical signal communication through wires. This is not energy efficient. |
| Coxial | Disadvantage: High noise contamination |
| Coxial | Disadvantage: Can be affected by external magnetic interference |
| Coxial | Disadvantage: Low bandwidth meaning less data can be transferred during download and upload. |
| Coxial | Easy installation |
| Coxial | Lowest cost of the three communication media. |
