Output of a PC connected to the input of another. Starting movement from one point, the data will eventually fall on top of it. The data in the ring always moving in the same direction. This network topology does not require additional hardware (servers, or hubs), but the failure of one computer stops working and the entire network. 4. Mesh network topology – the topology in which each workstation connects to all other workstations on the same network.
Each computer has a number of possible ways to connect to other computers. Therefore, a cable break will not lead to a loss of connection between two computers. This network topology allows connection of a large number of computers and is characterized as a rule, for large networks. 5. Mixed topology used several types of connecting computers together. It is rarely found in large companies and organizations.
Why do you need to know all kinds of topologies and their pros and cons? The scheme depends on a network of hardware and software. Topology is selected, based on the needs of the enterprise. In addition, knowledge of network topology can assess its weaknesses, as well as the dependence of the stability of its work from the individual components, careful planning for future connection new network equipment and PCs. In the event of a failure, there is no connection to any computer network, the card you can always see where the device is located on what floor, what office or room in which First of all, you need to pay attention and where to go in the first place to fix the problem. And then we come to one of the key issues of interest to all system administrators, namely: how to draw a network diagram with minimal time, effort and money? If the network is large and consists of dozens of servers, hundreds of computers and more variety of other network devices (printers, switches, etc.), even an experienced system administrator – not mention the opener – it is very difficult to quickly understand all the connections between network equipment. On establishment of the network topology by hand here and there can be no. Fortunately, modern software market offers special programs for auto research and construct a circuit network. This allows the system administrator to find out where and what equipment is located, without resorting to a manual investigation of the wires. Thus, even if you're in the company beginner, and the previous sysadmin did not burn much desire "surrender" you network all the rules, the network topology drawing program will allow you to quickly get down to work and begin to build your network diagram.
