Various Kinds of Computer Network Topology

Various Kinds of Computer Network Topology1. Ring TopologyIn the ring topology each computer connecting to another computer, and so on until it returns again to the computer first, and form a circle so called ring, this topology communicate using the data token to control access rights computers to receive data, such as a computer 1 will send the file to the computer 4 , then the data will pass through the computer 2 and 3 to be received by the computer 4, so a computer will resume sending data if the destination is not the IP address him.Network topologyThe advantages of the computer network ring topology is the ease of installation and the installation process, the amount of the lan cable slightly thus saving costs.The most fatal shortcomings of this topology is, if one of the computers or its cable problematic, then the data transmission will be interrupted even error.
2. Bus TopologyComputer network topology bus organized as a queue and use only one coaxial cable and each computer connected to the cable using BNC connectors, and both ends of the coaxial cable to be terminated by a terminator.Network topologyThe advantages of the bus is almost the same with the ring, the cable used is not a lot and saves installation costs.Shortage of bus topology in case of trouble or problems on one computer can disrupt other computer networks, and for this topology is very difficult to detect disturbances, frequent occurrence of data queue, and if the distance is too far away to be using repeaters.
 3. Star TopologyThis topology is formed like a star because all computers connected to a hub or switch with a UTP cable, so that the hub / switch was the center of the network and served to control data traffic, so if the computer 1 wants to send data to the computer 4, the data will be sent to switch and immediately send it to the destination computer without passing through another computer. Computer network topology is the most widely used today because of its advantages more.Network topologyThe advantages of this topology is very easy to detect where the computer is broken, it is easy to perform addition or subtraction without disturbing the other computer, and the security level of data higher.The drawback of this computer is the network topology, requires a high cost for installation, as it requires a lot of wires and switches / hubs and network stability is highly dependent on the central terminal, so that if the switch / hub impaired, then the entire network will be disrupted.4. Mesh TopologyIn this topology each computer will be connected to another computer in the network using a single cable, so the data transmission process will directly reach the destination computer without going through another computer or a switch or hub.understanding of computer network topologyKelebihanya is the delivery process faster and without going through another machine, if a computer crashes will not interfere with other computers.Disadvantages of this topology is clear, it will take very much cost because it requires enormous amount of wiring and each computer must have a Port I / O are many, besides the installation process is very complicated.
 5. Topology TreeComputer network topology Tree is a combination of some of the star topologies by connecting the bus topology, so any star topology will be connected to a star topology the other using a bus topology, usually in this topology there are several levels of network, and the network is at a higher level can control network which is at a lower level.types of computer network topologyExcess tree topology is easy to find a fault and also easily make changes to the network if necessary.Its shortcomings are using a lot of wiring, frequent crashes and slow, if something goes wrong on the network level is high, then low-level network will be disrupted as well.There's more topology that I have not discussed above, but here are some frequently used topology, choose the topology that suits your needs and hopefully this article
