Introduction to Computer Network Topology

Network expansion A new cable is plugged in from the new node to the hub. It tends to be little expensive. Ethernet bus topologies are relatively easy to install and don't require much cabling compared to the alternatives. The decision on which topology to use can be influenced by a number of factors. It also acts as a repeater for the data flow. All devices connected to a central cable, called the bus or backbone.

Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. It can be used for describing physical as well as logical type of arrangement of the nodes involved in the network. But it is costly and wiring is tough! The bus architecture has several common instances which include the one in the motherboard, of most computers and some with the versions of the Ethernet. Hybrid network topologies are more flexible, reliable, and have increased fault tolerance, the faults in them can be easily diagnosed and corrected, new nodes can be easily added. It is a physical star, but logically, the nodes communicate as a bus, e. How nodes in a network are connected to each other and communicate is determined by the topology.

A router is used to search multiple paths and determine the best path for the data. This shape does not necessarily correspond to the actual physical layout of the devices on the network. The network could consist of a bus running vertically through the building to provide network access to each floor. There are two types of mesh topologies, Partial and Full. In this way, the data is transferred in not a one way route but in a multiple access pathways and that all the workstations are functioning in data receiving and data sending at the same time. A failure in any single connection disrupts the ring topology thus also making ring topology a rare choice for network topologies. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message.

. That bus trunk acts as the mother cable or the backbone of such a topology. It makes it easy for adding more connections and station in the topology as daisy chaining and causes the data flow to be transmitted in such a way that all the signals are transmitted station to station one after the other in a sequence that causes them to end up in their desired destination. Recently, the Bead Bar purchased 14 desktop computer, 2 notebook computer, and 1 handheld computer. Note this this topology works with the design of a star and bus topology combined. Star topology is the simplest and most comprehensible example of a centralized network there is.

Messages are detected by all nodes but are accepted only by the node s to which they are addressed. This topology is mostly used in homes and offices today. This topology is used in real-life where scalability and high performance is important, for example Internet Service Providers. The transmission medium has a physical beginning and an end. Star topology requires more cable as compared to other topologies but it mode robust as a failure in one cable will only disconnect the specific connected computer via that cable to the central device.

These, however, are quite … expensive to install. It is more of an intangible concept that is used normally when initially in the developmental stages of designing the network. Shield volcanoes are the largest of the three types of volcanoes,built from basaltic lava flows and shaped like a gentle dome. A major disadvantage of this type of network topology is that if the central hub fails, all computers connected to that hub would be disconnected. Hybrid Topology In hybrid topology there are more than one topology used to connect computers in a network.

But at the same time hybrid topologies often are sufficiently expensive and difficult for managing. As in most fantasy novels, the main characters are in an ulterior world, which is comparable. Let me explain them to you. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. The main advantage o … f this is that if one device goes down, the others stay up. Ring In ring topology, the computers in the network are connected in a circular fashion, and the data travels in one direction. Essentially, it is the topological structure of a network, and may be depicted physically or logically.

All messages travel though the topology either in a clockwise direction or anti-clockwise direction. Figure below shows the star topology architecture In a Mesh topology nodes are connected to each other in a redundant fashion with multiple connections. Common examples are star ring networks and star bus networks. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to. Due to it's increased costs there are two types or versions of this topology: Full Mesh and Partial Mesh. Since the star topology has a central connection point, this design is more flexible than a ring or bus topology which requires every node to be directly connected to one another node or utilize.
