what is topology in computer

  •  

In mesh topology, each computer is connected to every other computer in point-to-point mode as shown in figure 5. In a ring network, packets of data travel from one device to the next until they reach their destination. Computers in one branch can transmit signals through one or more host computers to computers in other branches. Bus Topology. The network of tree topology can be easily expanded by creating new branches, so the use of this topology is more. Together, devices in a ring topology are referred to as a ring network.. ; Logical topology defines the way in which data actually passes through the network from … The configuration, or topology, of a network is key to determining its performance. Internet is the key technology in the present time and it depends upon the network topology. Out of all of the different topology types, the bus is the most frequently used of all. A computer that is no longer connected to a computer is called a peripheral computer. Computer Network Topologies Maninder Kaur professormaninder@gmail.com What is a Topology? In Computer Networking, tree topology is known as a combination of a Bus and Start network topology. The bus topology is an essential component of a LAN’s Ethernet connection, in which it serves as the central cable to which all of the network’s devices connect. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology. Computer Network Topology is a structure or layout which defines how devices such as the hub, switch, router, PC, or any nodes are connected to the network.Topologies can be physical or logical. Each networked device is connected to two others, like points on a circle. network topology: A network topology is the arrangement of a network, including its nodes and connecting lines. They describe the physical and logical arrangement of the network nodes. Internet is the key technology in the present time and it depends upon the network topology. Among these are certain questions in geometry investigated by Leonhard Euler.His 1736 paper on the Seven Bridges of Königsberg is regarded as one of the first practical applications of topology. This topology is the most preferred and popular model. The following are the disadvantages of ring topology: It is relatively expensive to construct the ring topology. Computer Network Topology. Two or more devices connect to a link; two or more links form a topology. 5) Mesh Topology. The main advantages of this topology are better flexibility and scalability. • Network topologies describe the ways in which the elements of a network are mapped. A ring topology is a network configuration where device connections create a circular data path. Topology, as a well-defined mathematical discipline, originates in the early part of the twentieth century, but some isolated results can be traced back several centuries. Network topology is the way a network is arranged, including the physical or logical description of how links and nodes are set up to relate to each other. The topology of a network is the geometric representation of the relationship of all links and linking devices (usually called nodes) to one another. In a ring topology, the network that connects to the computers form a logical ring-like communication path.In a ring at a point, there could be two paths to move one is left and the other is right. Tree network topology is the simplest topology in which only one route exists between any two nodes on the network. The term topology in computer networking refers to the way in which a network is laid out physically. The failure of one node in the ring topology affects the other nodes in the ring. Physical topology refers to the actual structure of the network. Ring topology shares many of bus topology's disadvantages so its use is limited to networks that demand high throughput. Network Topology is the structure and arrangement of components of a computer communication system. Similarly, in a computer network, a connected device can do communication from either side to reach another device or server in-ring topology.
