Alternately, network topology may describe how the data is transferred between these nodes. The topology is a representation of a network. A topology is the layout of how a network communicates with different devices. The intermediate nodes repeat (re transmit) the data to keep the signal strong. It defines the way different nodes are placed and interconnected with each other. Classification of Computer Networks based on: formed by the arrangement of interconnected, Each network host is connected to a central hub/switch, All signals transmission through the hub; if down, entire. There are two types of network topologies: physical and logical. Main Disadvantage: The entire network shuts down if there is a break in the main wire and it can be difficult to identify the problem if the network shuts down. Network topology is a graphical representation of electric circuits. The CWM topology subsystem has been redesigned in Release 11 of CWM to provide more efficient navigation, modularity and scalability.

Assistant Professor, Department of CSE, Bengal Institute of Technology and Management, Santiniketan The section 2 is a brief description of physical topologies. Share it! The arrangement of a computer network is referred to as topology. • Here, some logical layout of topology. RING In ring topology, the computers in the network are connected in a circular fashion, and the data travels in one direction. stream Ring Topology: A local-area network whose topology is a ring. Network topology is the arrangement of the elements (links, nodes, etc.) N etwork topology is the arrangement of the different networking elements like network links, computers, switches, nodes, Wi-Fi access points, laptops and other network devices in a computer network. These qualities may include a certain level of speed and performance, power usage, wiring or routing complexity, cost, redundancy and reliability, or a combination of these or other factors. Disadvantages: Aggregate network bandwidth is bottlenecked by the weakest link between two nodes. Each computer is directly connected to the next computer, forming a single pathway for signals through the network. {{{;�}�#�tp�8_\. %PDF-1.3 PDF | This paper evaluates and analyzes the basic types of network topologies which include the bus, star, ring and mesh topology. << To define network topology geometry, there is two method 1. • The star topology reduces the chance of network failure by connecting all of the systems to a central node. �������� Network Topology 4. It offers a high level of redundancy, so even if one network cable fails, still data has an alternative path to reach its destination. The section 3 introduces the logical topologies and finally conclusions are discussed in section 4. One can think of a topology as a network's virtual shape or structure. Having the map of a network’s topology on hand is very useful for understanding how devices connect to each other and the best techniques for troubleshooting. e.g. One major advantage of the Tree Network Topology is the ease at which the network can be expanded. A star topology generally consists of a central hub. It is best … The physical topology describes the layout of computers and where the workstations are positioned. Star Topology Star Topology Bus Topology. The systems in a star topology do not connect to each other, but instead pass messages to the central core that, in turn, passes the message to either all other systems or the specific destination system depending on the network design. Primary-Secondary: In this, one device controls the traffic and all other devices transmit through primary device. Mesh topology is the kind of topology, in which all the nodes are connected with all … • Common topologies: –Bus, ring, star, mesh and wireless. 4. This shape does not necessarily correspond to the actual physical layout of the devices on the network. A topology is a map of an internetwork that indicates network segments, interconnection points, and user communities. Linear Bus Topology. layer 1 is the physical layer.
