Net-Cyber Crime

Network topology is a section that describes the relationship between computers that were built based on usability, resource constraints and cost limitations, network topologies means that there can be tailored to the circumstances on the ground.There is some form of network topology as follows.
1. Bus TopologyThis topology is the initial topology is used to connect a computer. In this topology each computer will be connected to a long cable with a terminal, and at the end of the Kable must end with a terminator. This topology is very rarely used in building a network of ordinary computers because it has some shortcomings such as its collision possibility of a data stream, if one device is broken or there is damage to one part of the computer network will not function immediately before the damage is solved.
Figure bus topologyThis topology uses Kable Coaxial initially as a medium of instruction data and information. But at the moment this topology in computer networking by using cabal fiber optic (fiber optic), but combined with other network topologies to maximize performance.
2. Ring TopologyAtay ring topology is often called the ring topology is a network topology in which each computer connected to make a circle. With a sense every computer that is connected into a network of inter-connected to two other computers to form a network similar to the shape of a ring.

The advantages of this topology is the cable used can be saved. But the lack of this is the development of the network topology will be difficult because each computer will be connected to each other.
3. Token Ring topologyThis topology is similar to the ring topology but making more perfected. Can be seen from the difference image.
4. Star TopologyStar topology or more often called star topology. In this topology we have to use another tool to help connect computer networks. Examples of tools in use here is a hub, switch, etc..
The advantage of this topology is very much all of them allows admin to manage the network, allowing the addition of a computer or terminal, ease of detecting defects and errors in the network. But with its many advantages in terms of topology is not without shortcomings. The drawback to such extravagance cables, centralized control on the hub sometimes be critical problems that in case of damage to the network hub, then all will not be in use.
5. Tree TopologyTopology also called tree or hierarchical topology and can also be called a multilevel topology is a topology that can be used on the network in the multi-storey office space.
The central hub or who are at the very top is the active central central while underneath is a passive central.I got here a little pemaran in this article and I will continue in the next article with great jariangan to build, and how penanggulangnan problems on the network.
