Understanding And Various Computer Network Topology

             Definition of computer network topology is a method or concept for connecting several or many computers at once into an interconnected network. And any kind of computer network topology will differ in terms of data transfer speed, cost of manufacture, as well as its ease of maintenance processes. As well as any type of computer network topology has advantages and disadvantages of each. There are various topologies such as ring topology, star, bus, mesh, and the tree that will be discussed in the blog to learn this computer.

            Various Kinds of Computer Network Topology:

1. Topology Ring

            In the ring topology each computer is connected to another computer, and so on until returning 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, for example, the 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 continue sending data if the destination is not the IP address him.

• The advantages of computer network topology ring is in the process of installation and ease of installation , use a little amount lan cables thus saving costs.
• The most fatal shortcoming of this topology is , if one of the computers or its cable problem , then the data transmission will be interrupted even error.

2. Bus Topology

Computer network topology bus neatly arranged like 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 must be terminated by a terminator.

• The advantages of the bus is almost the same as the ring , the cable used is not much and saves installation costs.
• Shortage of bus topology is that if there is interference or problems on one computer can interfere with other computer networks , and this topology is very difficult to detect disturbances , frequent occurrence of data queue , and if the distance is too far to be using a repeater.

3. Star topology

This topology is formed like a star because all computers connected to a hub or switch with 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.

• The advantages of this topology is very easy to detect which computer is broken , it is easy to perform addition or subtraction without disturbing the other computer , as well as the security level of the data higher.
• The drawback of this computer is the network topology , requires a high cost for installation , as it requires a lot of cables and switches / hubs and network stability is highly dependent on the central terminal , so that if a switch / hub impaired , then the entire network will be disrupted.

4. Mesh Topology

In 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.

• Excess is the shipping process faster and without going through another computer , if one of the computers were damaged will not interfere with other computers .
• Disadvantages of this topology is clear , it will take very many costs because it requires a huge amount of cable and each computer must have a Port I / O that many , but it is very complicated installation process.

5. Topology Tree

Computer network topology Tree is a combination of several star topology that connecting it to 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 networks , and the networks are at a higher level can control networks that are at a lower level.

• Excess tree topology is easy to find a fault and also easily make changes to the network if necessary .
• Its shortcoming is using a lot of wiring , frequent collisions and slow , if something goes wrong on the network level is high, then low-level network will be disrupted as well.
