Topologies in Computer Network Design
Computer network design needs good understanding of topologies like ring, star, bus and so forth. Designing computer network needs to meet certain rules and these set of rules are referred to as topology. Nowadays, the most widely used topology is Ethernet which compose of computers as well as peripheral cables in specific ways. It’s because of the reason that Ethernet is relatively affordable, easy to set up and use and also, fast. The truth is, Ethernet comes in two forms and these are fast and standard Ethernet.
As you read on the next paragraphs, you are going to be mindful about other topologies used which can help you have better understanding of how to create complex network.
Number 1. Bus topology – when connecting a device, it actually uses a backbone in this type of topology. For this reason, the backbone has got cable that serve as shared communication medium to which to her devices may be connected on. Not many is needed when it comes to the cable and the best thing about this is that they’re easy to install. They have the best performance particularly when you have limited devices.
Number 2. Ring topology – in this kind of computer network design, there will be two neighbors for every device in relation to the communication. As a result, every piece of data is travelling either counterclockwise or clockwise in same direction. If there is any failure in the cable, the entire network stalls and eventually fail.
When using ring network, every device has two neighbors for the communication process. All the messages are travelling through a ring in same direction. If the cable or the device failed, then it’s going to break the loop that will take down the entire network.
Number 3. Star topology – for this type of topology, you might find this in most residential properties. It is featuring a connection point like a hub switch or router and the devices are normally using UTP Ethernet to connect.
Number 4. Tree topology – in relation to this computer network design, it is using multiple start topologies that are connected onto a bus. This provides excellent expandability of network and it’s way better compared to a bus or star.
Number 5. Mesh topology – such computer network design is using routes concept. All of the messages that are sent in this topology format are given with its set path before it is able to reach its final destination. Whether you believe it or not, the internet is a very popular example of mesh routing.
