network topology advantages and disadvantages pdf

The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations. Logical topology was discussed in the Protocol chapter.

The configuration, or topology, of a network is key to determining its performance. 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. There are numerous ways a network can be arranged, all with different pros and cons, and some are more useful in certain circumstances than others.

The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.

Logical topology was discussed in the Protocol chapter. The following sections discuss the physical topologies used in networks and other related topics. A linear bus topology consists of a main run of cable with a terminator at each end See fig. All nodes file server, workstations, and peripherals are connected to the linear cable. A star topology is designed with each node file server, workstations, and peripherals connected directly to a central network hub, switch, or concentrator See fig.

Data on a star network passes through the hub, switch, or concentrator before continuing to its destination. The hub, switch, or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable. A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable See fig.

Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs. A consideration in setting up a tree topology using Ethernet protocol is the rule. One aspect of the Ethernet protocol requires that a signal sent out on the network cable reach every part of the network within a specified length of time.

Each concentrator or repeater that a signal goes through adds a small amount of time. In addition, only 3 of the segments may be populated trunk segments if they are made of coaxial cable. A populated segment is one that has one or more nodes attached to it. In Figure 4, the rule is adhered to. NOTE: This rule does not apply to other network protocols or Ethernet networks where all fiber optic cabling or a combination of a fiber backbone with UTP cabling is used.

If there is a combination of fiber optic backbone and UTP cabling, the rule would translate to a rule. The speed of networking switches is vastly improved over older technologies, and while every effort should be made to limit network segment traversal, efficient switching can allow much larger numbers of segments to be traversed with little or no impact to the network.

Now, let us discuss about the basic terminology involved in this network topology. Network topology is also called as Graph theory. Like it? That is, all of the nodes are connected in a closed loop. RING Topology. The logical or the signal topology and 2.

Advantages and Disadvantages of Different Network Topologies A network topology refers to the way in which nodes in a network are connected to one another. The other nodes on the system cannot connect to one another except through the hub. If one link becomes unavailable, it does not affect the entire network. To get Configuration and installation for hybrid topology required to be much efficient. It has better performance in bigger networks with heavy traffic because of token passing.

BUS Topology

This multiple choice questions and answers type Data Communication and Networking Online Test section contains all the suitable and related MCQs of the Network topology ie eight basic topologies: point-to-point, bus, star, ring or circular, mesh, tree, hybrid, or daisy chain Only. All of these Questions have been hand picked from the Question paper of various competitive exams. Nevertheless, there is much that we do know about sets and this book is the beginning of the story. To browse Academia. We do not know the complete answer to this question.

Chapter 5: Topology

Network Topology is the schematic description of a network arrangement, connecting various nodes sender and receiver through lines of connection.

Topology is derived from two Greek words topo and logy, where topo means 'place' and logy means 'study'. In computer networks, a topology is used to explain how a network is physically connected and the logical flow of information in the network. A topology mainly describes how devices are connected and interact with each other using communication links. Network topology defines the layout, virtual shape, or structure of the network, not only physically but also logically. A network can have one physical topology and multiple logical topologies at the same time. In this blog, we will mainly concentrate on physical topologies.
