Infrared technology is used for short or medium range communications. It is a wireless mobile technology used for device communication. Some disadvantages would be that it has a short transmission range and is unable to penetrate through walls. On the other hand the devices are very cheap and are compact, lightweight and consume low power.

Fibre Optic broadband is promising super-fast speeds for your internet. Its name comes from the use of plastic or glass cables, which allow for faster data transfer compared to the standard copper wires which are used in regular broadband connections. One main strength is that they do not have speed limits or bandwidth limitations. One main weakness is that installation is very expensive so using normal copper UTP cables is preferred.

A router is a device which forwards data packets between networks. It does this with the use of different routes towards each network. A router also saves information based on all the networks it is connected to, with information on how busy the paths are to each network. This information is then used to judge the best way to send data packets.

Strengths:

Can connect multiple users to the internet.

Easy to set up and use.

Can be made very secure for devices connected.

Weaknesses:

Can be quite expensive to setup.

If not secured properly (with password), anyone can connect.

Routes to networks may often be very busy.

Wi-Fi works by having a wireless access point receive information by a broadband connection which is then converted to radio waves and is emitted. Devices such as smartphones and computers will pick up these radio waves if it has a wireless adapter. Wi-Fi is a wireless local area network (WLAN).

Strengths:

No wires are required so the connection is faster and more efficient.

You can move around an area easier without being restricted by wires.

Wi-Fi is more accessible as you can connect to the internet in most public places.

Weaknesses:

Limited coverage as the radio waves are weak which prevents you from connecting to the internet via Wi-Fi wherever you want.

The speed with Wi-Fi connection is lower than a wired one especially the further you are away from the router.

A network switch (also called switching hub, bridging hub and officially MAC bridge) is a computer networking device that connects devices together on a computer network by using pocket switching. ( Pocket switching is a method of grouping data and transmitted over a digital network). The computer network receives, processes and forwards data to the destination device.

A network switch is a multipart network bridge that uses hardware addresses to process and forward data
-Strengths
>Switches directly connect to workstations
>Switches reduce workload of computers
>Increase network performance
Weaknesses
>Expensive
>Difficult to install
>Susceptible to security riskThis is a network hub.

Shielded Twisted Pair is the ordinary copper wire that connects home and many business computers to the telephone company. Twisted pair is used to cancel out electromagnetic interference from external sources. e.g. power lines, radar systems.
Advantages of Shielded Twisted Pair cabling is that it automatically repels interference from external sources, STP cables can transmit data quickly at speeds of up to 100 megabits per second and that data being sent via STP cabling is more secure then data being sent via other cabling types.
However STP cables are more expensive and more difficult to install then UTP cables.

The lasers uses a high amount of power laser beams to transmit light signals.

The system is sometimes called a “free-Space” laser system because the beams travel directly through the air. For an example, setting up a high bandwidth data link between two line of sight buildings can make use of a free-space system.

Laser communications are also used to exchange data between the satellites. In space, the beams remain strong and tightly focussed.

Advantages
Has a wider bandwidth compared to infrared which means the network is faster
Can be set up quickly which means it is a lot more ideal for outside events

Disadvantages
Is affected by the weather when the beams are blocked by fog or haze, which can course delays if presentations are being made
Requires lines-of-sight work which can also cause problems if someone or something gets in the way of the path of the laser beans

A network hub is a device that most people have in their homes.
A network hub is connected via an Ethernet cable and is a connection point for devices that are in a network. A hub does the same thing as a network switch but a hub is the more basic networking device.
The strengths of a network hub are that it is able to connect multiple devices to it, they are very cheap and they do not need much configuration.
The weaknesses include:
A hub is unable to support a large network because each time a device is added, the slower the network gets, a hub only runs at half duplex and it does not have the intelligence to filter traffic so it can only send out data in one direction at once, not simultaneously.

A microwave link is a communication's system that uses a beam of radio waves in the microwave frequency range to transmit things like Video's, Audio or data between two locations, which can be from just a few feet or meters to several miles or kilometres apart. It I mainly used in remote areas where things like wired communications is not possible to be installed. Frequencies range from 1GHz to 30GHz they are banded into different groups UHF, SHF, EHF and it lies on the upper portion of the radio frequency spectrum.

Advantages
> They are able to transmit large quantities of data.
> Does not require physical cables.
> Wideband width.
> Multiple channels available.

Disadvantages
> Microwave radio systems do not pass through solid objects.
> Electromagnetic interference can degrade the signal.
> Towers are expensive to build.
> Microwave radio communications can also be degraded by heavy moisture in the atmosphere.

It is a mixture of two or more types of network topologies (connection of various links/nodes to transfer, send or receive data).

Advantages:
-Reliable, they are easy to troubleshoot and find faults.
-Flexible, the infrastructure can be specific to the business or company.
-Effective, it contains more than one topology and often has more benefits than negatives.

Disadvantages:
-Complexity of Design, hard to design / manage. Often requires a specialist designer to develop the ideal HNH.
-Cost, very expensive to link, the bigger the infrastructure the more cables and cooling you will require.

Unshielded twisted pair (UTP) cables are found in many Ethernet networks and telephone systems. UTP cables have each pair twisted together and then encased inside the tubing without any other protection. The UTP cables are the most popular type of cabling. UTP cables are the most commonly used networking cables on the market and are considered to be the fastest copper-based medium available. They are less expensive than STP cables, costing less per meter than other types of LAN cabling. They have an external diameter of approximately .43 cm, making it a smaller cable than STP cable and easier to work with during installation, as it doesn't fill the wiring ducts as fast as other cables. It comes in various categories, from Level 1 for in-home telephone wiring to Level 6 for Ethernet networking. It is the most compatible cabling and can be used with most other major networking systems and does not require grounding. UTP cables are susceptible to radio frequency interference (RFI) and electromagnetic interference (EMI) such as is caused from the microwave, and they are more prone to electronic noise and interference than other forms of cable. As well, the distance between the signal boosts is shorter with UTP cable than for coaxial and fibre-optic cables, making it less able to carry the signal for long-distance networking.

The Coaxial Cable is a type of cable that allows for the transmission of video and audio signals.  It's primarily used by TV companies so that they can connect their satellite antenna facilities to customer homes as well as businesses. An advantage is that they're able to transmit both Analogue and Digital signals which makes them a good choice for customers, however a disadvantage of the coaxial cable is that when compared to fibre optic it has a much lower bandwidth.
