As we discussed earlier in the article Definition, Function And Types of Computer Networks, that computer networks are divided into several types, and for the type of network based on the topology can be divided into several models of network topologies include Ring topology, bus topology, Topology Star, Mesh Topology and Topology Tree. and on this occasion will top computers further review into 5 types of computer networks Based on the topology, if my friend had not understood about the topology should not we start out by knowing what the network topology
Understanding Network Topology
Computer network topology is a concept or method that is used to connect two or more computers into a network of inter-connected. Each model of the network topology itself will have other differences between the difference in terms of cost to make, the speed of transferring data and also in terms of ease of manufacture and maintenance nyah. of understanding if my friend had a computer to build a computer network, pal can determine the topology model which can mate later use.
Various - Various Computer Network Topology Frequently Used
1. Bus Topology
In the bus topology model of a computer connected to a network to be neatly arranged as a queue associated with a coaxial cable and BNC connector, then the end of the network using a terminator as the closing device.

Advantages and Disadvantages of Computer Network Topology Bus
The advantages of the bus topology are to make it very easy, but it costs that are used to create a network with a bus topology is very cheap.
Shortage of bus topology is that if there is a problem or there is interference on one computer, then all the computers connected to this network will also be affected, in addition to the topology is also commonly found a problem that caused the data queue. and ap Abi laws used to remotely this topology must be equipped with a Repeater to men gu bung Kanya.
2. Topology Ring
In the model of ring topology each computer will be connected with other computer continuously and then connect it to the computer first, so that the network model will form a circle or ring, this topology using coaxial cable and BNC connectors, to be able to communicate this topology uses data token which is used as a controller computer access privileges for receiving data transmitted. for example, if the computer 1 will transmit data to the computer 3, the data sent will pass the second computer and then the computer 3, if the IP Andress destination computer does not match then the data will be forwarded to the destination IP address matching.

Advantages and Disadvantages of Computer Network Topology Ring
The advantages of the model ring topology is the ease in terms Pemba Tanya, not only that this topology can avoid collisions of data files that are sent from each - each computer, in addition to the terms of use of the number of LAN cable, this topology can also be said to be efficient so as to reduce the cost of manufacture, the status of the computer connected to this ring topology is the same.
A shortage of models ring topology is, if one of the cables connected computer or on the network has an error then all the data transmission process in the network will be disrupted. besides the difficulty of the development of the model topology ring toward a broader also become one of the shortcomings of this topology model.
3. Star Topology
Network topology model this one is very individual because it forms a star. To be able to connect one computer to another computer, this topology requires the hub or switch and cables used are equipped with cable UTP RJ45 connector types. Perngakat hub or switch duty to control the data and to be the center of this network. so if there is a transmission of data from one computer to the computer to 2, then the hub or switch that determines which computer IP that will be addressed without passing through other computers. today topology is most commonly used because many Kele BiH Anya than model Bus and Ring network topology.

Advantages and Disadvantages of Computer Network Topology Star
Excess star topology is the topology is very flexible and to detect if an interruption occurs on a computer connected to a network, network control can be done very easily, and also when we will add or subtract the computer also will not have trouble. the star network topology model also has a level of data security is higher than with other network topology model.
Shortage of star topology is to build this network, we require a high cost, because the model of this topology requires a lot of wires and procurement switch / hub, the topology is highly dependent on the switch / hub of the factor of stability, so that if a component switches or hubs are damaged or interference then the entire network will also be impaired.
4. Mesh Topology
In the mesh topology to connect computers to each other can use a single cable, so in the process of sending data from one computer to the other computer will be able to directly reach the destination computer without passing through another computer or passing through the switch / hub.
The following Image of Mesh Topology
Advantages and Disadvantages of Computer Network Topology Mesh
The advantages of the mesh topology are in the process of sending data from one computer to the destination computer that can be done more quickly without going through a computer other than that, if there is damage to one of the computers, the other computers will not be disturbed or having problems too
Disadvantages of a mesh topology in terms of cost this topology is obviously going to take a lot of costs because of the need for cables that very much and also on each computer must have a Port I / O are also very much anyway, in addition to making this network topology installation process is also very complicated ,
5. Topology Tree
Model of the network topology tree or tree topology is commonly called a combination of several star topology that connecting it to the bus topology, star topology so each will be connected to the other by using a star topology bus topology. This topology usually has several levels of the network, and a network that has a higher-level position can control the network that has a lower position ting katana.
The following Image of Topology Tree
Advantages and Disadvantages of Topology Tree
- The advantages of the tree topology are ap Abi law we find fault and will also make changes to the network, then we can do it easily.
- Disadvantages of tree topology are to build a model of the network topology it cost a lot because of the need for cables, a component and connector that much. in addition to the type of topology is also frequent collisions and slow connection, not only is it in the event of a network error on a high level, it can disrupt the low-level network.
