Your neighbour decides to add the Internet to their home network and there are a lot of options for them. In a document, list their options using your own real options for an example and describe each one in detail. There are a lot of issues they may have to deal with. Make sure you are thorough in your descriptions.

The home network enables multiple devices e.g. PCs, tablets, etc to connect to each other, and connect to the internet.

There are many options to establish home network.

1.Wired

Wired network is always faster than wireless network. This use Ethernet over UTP cable. if you have a lot works to do or heavy work like playing games then wired home network is best choice. Before 2008 These networks were common. Given diagram explains simple wired home network setup with switch and broadband router.

Advantage:

· Typically, fast

· Secure and reliable

Dis-Advantage:

· This network will not work if the devices have no Ethernet port like tablets and smart phones.

· It is not easy and fast to setup. This may also result to messy.

· It is not easy for someone with mobile devices to connect.

There are different topology to establish network in wired network.

Topology escribe the ways in which the elements of a network are connected

Bus topology

Advantages of Bus Topology

It is easy to set up, handle, and implement.

It is best suited for small networks.

It costs very less.

Disadvantages of Bus Topology

The cable length is limited. This limits the number of network nodes that can be connected.

This network topology can perform well only for a limited number of nodes. When the number of devices connected to the bus increases, the efficiency decreases.

It is suitable for networks with low traffic. High traffic increases load on the bus, and the network efficiency drops.

Heavily dependent on the central bus. A fault in the bus leads to network failure.

Not easy to isolate faults in the network nodes.

Each device on the network “sees” all the data being transmitted, thus posing a security risk.

Ring Topology

Advantages of Ring Topology

The data being transmitted between two nodes passes through all the intermediate nodes. A central server is not required for the management of this topology.

data transmission is high-speed.

In comparison to a bus, a ring is better at handling load.

The adding or removing of network nodes is easy, as the process requires changing only two connections.

The configuration makes it easy to identify faults in network nodes.

In this topology, each node has the opportunity to transmit data. Thus, it is a very organized network topology.

It is less costly than a star topology.

Disadvantages of Ring Topology

The failure of a single node in the network can cause the entire network to fail.

The movement or changes made to network nodes affect the entire network’s performance.

Data sent from one node to another has to pass through all the intermediate nodes. This makes the transmission slower in comparison to that in a star topology. The transmission speed drops with an increase in the number of nodes.

There is heavy dependency on the wire connecting the network nodes in the ring.

Mesh Topology

Advantages of Mesh Topology

The arrangement of the network nodes is such that it is possible to transmit data from one node to many other nodes at the same time.

The failure of a single node does not cause the entire network to fail as there are alternate paths for data transmission.

It can handle heavy traffic, as there are dedicated paths between any two network nodes.

Point-to-point contact between every pair of nodes, makes it easy to identify faults.

Disadvantages of Mesh Topology

The arrangement wherein every network node is connected to every other node of the network, many connections serve no major purpose. This leads to redundancy of many network connections.

A lot of cabling is required. Thus, the costs incurred in setup and maintenance are high.

Owing to its complexity, the administration of a mesh network is difficult.

Star Topology

Advantages of Star Topology

Due to its centralized nature, the topology offers simplicity of operation.

It also achieves isolation of each device in the network.

Adding or removing network nodes is easy, and can be done without affecting the entire network.

As the analysis of traffic is easy, the topology poses lesser security risk.

Data packets do not have to pass through many nodes, like in the case of a ring network. Thus, with the use of a high-capacity central hub, traffic load can be handled at fairly decent speeds.

Disadvantages of Star Topology

Network operation depends on the functioning of the central hub. Hence, central hub failure leads to failure of the entire network.

Also, the number of nodes that can be added, depends on the capacity of the central hub.

The setup cost is quite high.

Tree Topology

Advantages of Tree Topology

The tree topology is useful in cases where a star or bus cannot be implemented individually. It is most-suited in networking multiple departments of a university or corporation, where each unit (star segment) functions separately, and is also connected with the main node (root node).

The advantages of centralization that are achieved in a star topology are inherited by the individual star segments in a tree network.

Each star segment gets a dedicated link from the central bus. Thus, failing of one segment does not affect the rest of the network.

Disadvantages of Tree Topology

As multiple segments are connected to a central bus, the network depends heavily on the bus. Its failure affects the entire network.

Owing to its size and complexity, maintenance is not easy and costs are high. Also, configuration is difficult in comparison to that in other topologies.

Though it is scalable, the number of nodes that can be added depends on the capacity of the central bus and on the cable type.

Star topology is best for wired home network.

Wireless Home network

Wireless network use Wi-Fi and are very quick and easy to install, but as mentioned above this is typically slower than wired network. It is cheaper than wired.

Advantages:

· Easy to setup (for End users)

· Allow easy access to smart devices or mobile devices (doesn’t require any port)

· There are no cables required.

Disadvantages:

· This network is not as secure as wired home network.

· Not as fast as wired

· Not as reliable as wired

Mixed home network

In this network both wired and wireless networks are mixed together to gain the profit of both.

In mixed network some devices are connect via Ethernet cables, while some devices like laptops, tablets, mobiles are connected wirelessly via Wi-Fi.
