Network topology is called a geometric shape that are distributed work stations and cables that connect. The workstations on a network communicate with each other through a physical connection and the topology of the object is to find the most economical and efficient connectivity, while providing the reliability of the system, to avoid waiting times at data transmission, allowing for better control of the network in an efficient and allow an increased number of computers on the network.
The most common forms we can find in these networks are:
Network Topology Bus
It all stations share the same communications channel, all data flowing through that channel and each one contains the information to it. It is one of the most used and can be found in so-called Ethernet. This type of network is easy to install, the amount of wire used is minimal, has a great flexibility to increase or decrease the number of stations and the failure of one station does not affect the network. However, the breaking of a cable can leave it completely destroyed. The drawbacks that we can find in this type of network are:
• The length can not exceed 2000 meters.
• Not too sure which other users can gather information without being detected.
• Having a single bus, but several stations try to transmit at a time, only one of them may do so. This implies that the more stations will have the network will be more complicated flow control.
Ring network topology
It all stations are connected together to form a ring, each station has only direct contact with two others. In the first networks of this type of data is moved in one direction, so that all information had to go through all the stations until you reach the destination where he stayed. The most modern networks have two channels and transmitted in different directions for each. Today we can find this setting in the IBM Token Ring networks. Such networks can increase or decrease the number of computers without difficulty, but with increasing the flow of information, the less response speed of the network. A fault in a locked station can leave the network, but a failure in a communications channel let blocked in its entirety, being difficult to locate the fault.
Star network topology
This type of computer network is the oldest. All the workstations are connected directly to the server and all communication are made necessarily by him. This topology allows you to add or remove machines easily. If a fault occurs in any of the stations have no impact on the overall functioning of the network, but if the server fails, the whole network will come tumbling down. The cost and implementation of such a computer network is expensive due to the large amount of wiring and the complexity of its structure.
Topology Star / Bus
This topology combines two types of networks mentioned above. Multiplex signal occupies the central computer in a star configuration, with certain work stations connected to it, and others connected with the bus multiplexers. This type of network offers advantages in buildings that have working groups separated by large distances.
As seen above, there are different types of networks topologies to connect computers, workstations, servers and other computer and network. Depending on the type of business or company, we can find a system or another.
