Network Topology: Definition, Types and Characteristics

---

Computer network serves to connect 2 or more computers. In its implementation there are several network topologies used.

The network topology itself is a method / concept that is used to connect two or more computers more, based on the geometric relationship between the basic elements composing the network, namely nodes, links, danstation.

Selection of network topology is based on network scale, cost, purpose, and users. The first topology used is the bus topology. Each topology has its own advantages and disadvantages. The structure or network used to connect one computer to another can be wired or wireless (wireless).

In practice, there are several types of computer network topologies that are used according to the network scale, objectives, costs, and users.

Each type of topology also has advantages and disadvantages so that in its use you must really pay attention to its designation.

Understanding Network Topology According to Experts

Some knowledge in the field of information technology has explained the meaning of computer network topology, including the following:

• Zymon Machajewski

Network topology is a set of computers that are connected together with one another with the main goal, namely to share resources. The internet is one of the resources that is currently widely used in a computer network.

• Jafar Noor Yudianto

Network topology is a system consisting of several computers that are designed to be able to share with each other resources (printer, CPU), communicate (e-mail, instant messages), and be able to access information (browser web).

• Umi Proboyekti

Network topology is a group of computers that are separate but interconnected in carrying out their duties. For example, two computers can be said to be connected if they can exchange information. This form of connection can be via copper wire, fiber optics, microwaves, communication satellites.

• Abdul Kadil

Network topology is a relationship of two nodes (generally in the form of a computer) or more whose main purpose is to exchange data.

• Izaas El Said

Computer Network Topology is a system where there are several computers that are connected to each other, so that they can share information and also the resources they have.

• Buddhi Irawan

Computer Network Topology is a system consisting of computers and other network devices that work together to achieve a common goal.

• Kristanto

Computer Network Topology is a group of autonomous computers that are connected to each other, using a single communication protocol so that all computers are interconnected This connected device can share information, programs, resources and can also use other hardware devices simultaneously, for example printers, hard disks, etc.

  ring topology

Ring topology or often referred to as ring topology is a network topology that is used for can connect a computer with other computers in a circular circuit like ring. This type of network topology generally only uses a LAN card so that each computer is connected.

The characteristics of the Ring Topology are:

The nodes that have been connected serially along the cable, with a network shape like a circle.
Very simple in layout like a kind of bus topology.
Data packets can flow in one direction (left or right) so that this collision can be avoided.
The problem faced is the same as the bus topology, that is, if one node is damaged, all nodes cannot communicate in the network.
The type of cable used is usually a UTP cable or Patch Cable (IBM type 6).

The advantages of ring topology are:

• • The cost for installation is very cheap.
  • Connection performance is quite good.
  • The installation and configuration process is quite easy.
  • Its implementation is very easy to do.

Disadvantages of Ring Topology are:

• • If a problem occurs, network troubleshooting is considered very complicated.
  • On this network, the data flow collision is very vulnerable to occur.
  • Connections on the network will be lost if one of the connections has a problem.

• Bus Topology

The bus topology is one of the simpler network topologies. In general, this network topology can be done on coaxial cable-based network installations.

This bus topology uses coaxial cable along the client node and connector. The types of connectors used are BNC, Terminator, and TBNC.

Characteristics of Bus Topology, namely:

• • Nodes that have been connected serially along the cable, and at both ends of the cable are closed with terminators.
  • Very simple in its installation.
  • Very economical in terms of cost.
  • Data packets that intersect on a cable.
  • No need for a hub, what is needed is a Tconnector on each ethernet card which is very much.
  • The problem that often occurs is if one of the nodes is damaged, then the entire network can go down, so that all nodes cannot communicate in the network.

The advantages of Bus Topology are:

• • Ease in adding a new client or workstation.
  • Easy to use and very simple.
  • Installation costs are very cheap because the cables used are few.

Disadvantages of Bus Topology are:

• • There are frequent collisions in data streams.
  • 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, it is disconnected, then this workstation computer will be disrupted.

• Star topology

Star topology or also known as star topology is a star-shaped network topology which generally uses a hub or switch for connections between clients. This computer network topology is most often used today because it has many advantages.

The characteristics of the Star Topology are:

• • Each node communicates directly with the concentrator (HUB).
  • If every data packet that enters the concentrator (HUB) can then be broadcast to all nodes connected very much (for example, using a 32-port hub), the performance on the network will increase down.
  • Very easy to develop.
  • If one of the ethernet cards is damaged, or one of the cables on the terminal is broken, then the whole on the network can still communicate or there is no downtime on the entire network the.
  • The type of cable used is usually the UTP type.

The advantages of the Star Topology are:

• • This network topology continues to run well even though one of the client computers is having problems.
  • The security level of data in this topology is quite good.
  • Users find it easier to detect problems on the network.
  • More flexible.

Disadvantages of Star Topology are:

• • This topology is considered expensive because it can use quite a lot of cables.
  • All computers on this network will have problems if the hub or switch is having problems.
  • This star topology is very dependent on the central terminal.

• Mesh Topology

Mesh topology is a topology that can be used for very many routes. The network in this topology uses a single cable so that the process of sending data is faster without going through a hub or switch.

The characteristics of the Mesh Topology are:

• • This mesh topology has a redundant relationship between existing devices.
  • The arrangement of each equipment in this network is connected to one another.
  • If the number of connected equipment is very large, of course this will be very difficult to control compared to only a few connected equipment.

The advantages of the Mesh Topology are:

• • The bandwidth limit can be quite large.
  • Data security in this network topology is very good.
  • There is no data flow collision because there are so many data transmission paths.

Disadvantages of Mesh Topology are:

• • The amount of cable needed is very large.
  • The cost of installing this mesh topology is very expensive because it uses a lot of cables.
  • The installation is also very complicated.

• Tree topology

Tree topology or tree topology is the result of a combination of bus topology and star topology. This tree topology is generally used for interconnection between hierarchies with different centers.

Advantages of Tree Topology:

• • Can and easily be developed into a wider network topology.
  • This topological arrangement is hierarchically centralized so that managing data becomes easier.

Disadvantages of Tree Topology:

• • This tree topology has slow network performance.
  • The use of cables is very much so that the installation costs become expensive.
  • This backbone cable is the center of this topology.
  • If the top computer is having problems, then the bottom computer will also have problems.

• Peer to Peer Topology

Peer to peer topology is a very simple network topology because it only connects 2 computers. In general, this peer to peer topology uses just one cable to connect the two computers so that they can share data with each other.

The advantages of Peer to Peer Topology are:

• • Very low installation costs.
  • Easy installation process.
  • Each computer can act as a server or client.

Disadvantages of Peer to Peer Topology, namely:

• • This topology is very difficult to develop.
  • Security in this topology is also often problematic.
  • The troubleshooting process is quite complicated.

• Linear Topology

Linear topology or often referred to as sequential bus topology. This topology generally only uses one main cable as a connector for each connection point on each computer.

The advantages of Linear Topology are:

• • Easy to develop.
  • Minimal use of cables.
  • The layout on the linear topology is simple and straightforward.
  • This topology does not require a central control.

Disadvantages of Liner Topology are:

• • Data traffic density is quite high.
  • Unsecured data security.

• Hybrid Topology

Hybrid topology is a combination of several different topologies and can form a new network. In other words, if there are two or more different network topologies connected in one network, the network topology will form a hybrid topology.

The advantages of Hybrid Topology are:

• • This topology is flexible.
  • Adding another connection to this topology is very easy.

Disadvantages of Hybrid Topology are:

• • The installation and setup process is quite complicated.
  • Management of this hybrid topology is very difficult to do.
  • The cost to create a topology is quite expensive

Computer Network Functions

• Can Save Costs

With this computer network, you can reduce costs for a peripheral device need, because you can use resources simultaneously. For example, printer devices can be used by many users, so you don't need to provide another printer for one computer.

• Keeping Information Reliable and Up to date

By creating a computer network with this centralized data storage system, users can open data from different places.

• Speed ​​up the Data Sharing Process

With this computer network, we can share data without using additional devices such as FlashDisk, because we can share data via a computer network.
