Network Topologies

Network Topologies is the arrangement of network.


Point-To-Point Topology 
- there are only two hosts that are connected to each other with a cable.

Advantages: 1- Faster in sending information
2- Do not have to wait to send the information

Problems: 1- Once the cable is broken, so cannot transfer the information
2- It only have one cable, so it means it cannot connect to other hosts.

Bus Topology
- there is only one cable that connected to multiple hosts.

Advantages: 1- There is only less cable needed than the other topology like 'Star topology'
2-  When user only need for a small network, bus topology is the easiest topology they can use for it.

Problems: 1- The hosts only connected to one cable, so it surely can be lagging.
2- When there is one host that is broken, so all the hosts is effected.

Star Topology
- all the devices are connected to one switch or hub or router.

Advantages: 1- It can be faster when sending the information.
2- There are switch, for example switch, it can be use for multiple hosts.

Problems: 1- It is expensive to buy the cables.
2- When the switch, hub or router is broken, so there is no connection.

Ring Topology
- there are many hosts that are connected to each other.

Advantages: 1- When there is one part that is disconnected, but there are still other ways to send the information.
2- It is faster when sending the information, because only one person that is using the cable.

Problems: 1- Queue up/ need to get the token ring before send the information
2- The information can be reads by the other hosts.

Mesh Topology 
- there is one host that is connected to many hosts.

There is two types of Mesh topology: 1- Partial and 2- Full Mesh.

Advantages: 1- It can be fast because there are many cables.
2- When one cable is broken, they can use other cable to send the information.

Problem: 1- many cables needed.
2- It is expensive.

Tree topology
- it is also known as Hierarchical topology.
- It is most commonly used network topology in today.

Advantages: 1- Fast sending of the information.
2- Suitable for office use.

Problems: 1- It is expensive.
2- Use many cables.
