Network Topology: In this opportunity, the teacher wants to share an article about Network Topology and its explanation:
Understanding Network Topology Is
Network Topology is a method or method used to connect one computer to another. The structure or network used to connect one computer to another can be either wired or wireless (without cables).
In practice, there are several types of computer network topologies that are used according to the network scale, objectives, costs, and users.
Types of Network Topology
1. Ring Topology
Ring Topology is a type of computer network topology that is used to connect one computer to another computer in an arrangement that has a circular shape similar to a ring.
Advantages of Ring Topology
- Cheap installation costs.
- The connection performance is quite good.
- The installation and configuration process is quite easy.
- The implementation is easy to do.
Lack of Ring Topology
- If a problem occurs, troubleshooting this network is somewhat complicated.
- On the Network Topology ring collision of data, flow is very easy to happen.
- The connection on the network will be lost if one of the connections experiences problems.
2. Bus Topology
Bus Topology is a very simple network topology. Usually, the network topology is done on a coaxial cable-based network installation.
The bus topology uses a coaxial cable along with the client node and the connector. The type of connector used is BNC, Terminator, and TBNC.
Advantages of Bus Topology
- Easy to add new clients and workstations.
- Easy to use and very simple.
- Low installation costs because the cable used is small.
Lack of Bus Topology
- Data flow collisions often occur.
- The process of sending and receiving data is less efficient.
- The old bus topology is difficult to develop.
- If there is a problem with the cable, for example, is lost, the workstation computer will be disrupted.
3. Star Topology
Star topology or commonly called a star topology is a star-shaped network topology that usually uses a hub or switch for connections between clients. The computer network topology is most often used today because it has many advantages.
Advantages of Star Topology
- The network topology is still running well even though one client computer has a problem.
- The level of data security in the topology is quite good.
- Users more easily detect problems on the network.
- More flexible.
Lack of Star Topology
- The topology is relatively expensive because it uses quite a lot of cable.
- All computers in the network will have problems if the hub or switch has a problem.
- Star topology is more dependent on the central terminal.
4. Mesh topology
Mesh topology is a topology that can be used for many routes. Networks in this topology use a single cable so that the process of sending data becomes faster without passing through a hub or switch.
Advantages of Mesh Topology
- A bandwidth limit is quite large.
- Data security in this topology is very good.
- No data flow collision occurs because there are so many data transmission lines.
Lack of Mesh Topology
- A lot of cables are needed.
- The cost of installing a mesh topology is very expensive because it uses a lot of cables.
- The installation is very complicated.
5. Tree Topology
Tree topology or tree topology is the result of a combination of bus topology and star topology. Tree topology is usually used for interconnection between hierarchies with different centers.
Advantages of Tree Topology
- It can and easily developed into a very broad network topology.
- The topology is centered in a hierarchical way so that data management becomes easier.
Lack of Tree Topology
- Tree topology has a slow network performance.
- Use a lot of cables so that the installation costs are expensive.
- Backbone cables are central to this topology.
- If the top computer has a problem, the bottom computer will have a problem.
6. Peer to Peer Topology
Peer to peer topology is a very simple network topology because it only connects 2 computers. Usually, the peer to peer topology uses just one cable to connect the two computers to be able to share various data.
Advantages of Peer to Peer Topology
- Installation costs are very cheap.
- Easy installation process.
- Each computer can act as a server or client.
Lack of Peer to Peer Topology
- This topology is very difficult to develop.
- Security in this topology often occurs problematic.
- The troubleshooting process is difficult.
7. Linear Topology
Linear topology or commonly referred to as sequential bus topology. This topology usually uses only one main cable as a connector for each connection point on each computer.
Advantages of Linear Topology
- Easy to develop.
- Less cable usage.
- The linear topology layout is simple and easy.
- The topology does not require central control.
Lack of Linear Topology
- Data traffic density is quite high.
- Data security is not guaranteed.
8. Hybrid Topology
A hybrid topology is a combination of several different topologies and forms a new network. In other words, if there are 2 or more different topologies connected in one network, the network topology will form a hybrid topology.
Advantages of Hybrid Topology
- This topology is flexible.
- Adding other connections to the topology is very easy.
Lack of Hybrid Topology
- The installation process and its settings are quite complicated.
- Management of hybrid topology is very difficult to do.
- The cost to make this topology is very expensive.
