Type of Network Topology: Bus, Ring, Star, Mesh, Tree, P2P, Hybrid

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.

What Is Network Topology? Best Guide to Types and Diagrams

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.

2. Network Topologies. • Topology - Physical and logical network layout. – Physical – actual layout of the computer cables and other network devices. – Logical.

network topology advantages and disadvantages pdf

Network Topology is the schematic description of a network arrangement, connecting various nodes sender and receiver through lines of connection. Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called Linear Bus topology.

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.

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.

Types of Network 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.

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.

Network topologies describe the methods in which all the elements of a network are mapped. The topology term refers to both the physical and logical layout of a network. In this network topology tutorial, we will explain: What is Topology? Types of Networking Topologies Two main types of networking topologies are 1 Physical topology 2 Logical topology Physical topology: This type of network is an actual layout of the computer cables and other network devices Logical topology: Logical topology gives insight's about network's physical design.

Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания. Я видел схему. Она знала, что это. Как и то, что шахта лифта защищена усиленным бетоном. Сквозь клубящийся дым Сьюзан кое-как добралась до дверцы лифта, но тут же увидела, что индикатор вызова не горит. Она принялась нажимать кнопки безжизненной панели, затем, опустившись на колени, в отчаянии заколотила в дверь и тут же замерла. За дверью послышалось какое-то жужжание, словно кабина была на месте.

Network topologies define the layout, virtual shape or structure of network, not only physically but also logically. The way in which different systems and nodes are.

Танкадо рассудил, что, если он погибнет, деньги ему не понадобятся, - так почему бы не вручить миру маленький прощальный подарок. Оба замолчали. Сьюзан глубоко дышала, словно пытаясь вобрать в себя ужасную правду. Энсей Танкадо создал не поддающийся взлому код. Он держит нас в заложниках.

 - Но как только я узнаю, что вы следите за мной, я немедленно расскажу всю эту историю журналистам. Я расскажу, что Цифровая крепость - это большая липа, и отправлю на дно все ваше мерзкое ведомство. Стратмор мысленно взвешивал это предложение.

 Кто вам дал наш номер. - La Guia Telefonica - желтые страницы. - Да, сэр, мы внесены туда как агентство сопровождения.

Некорректный ввод только ускорит процесс разрушения. Два некорректных ввода - и шифр навсегда захлопнется от нас на замок. Тогда всему придет конец.

Название показалось ему чересчур земным для такого агрессора. - Червь, - недовольно сказал Джабба.  - Никакой усложненной структуры, один лишь инстинкт: жри, опорожняйся и ползи.

Все они подверглись проверке на полиграф-машине, иными словами - на детекторе лжи: были тщательно проверены их родственники, изучены особенности почерка, и с каждым провели множество собеседований на всевозможные темы, включая сексуальную ориентацию и соответствующие предпочтения. Когда интервьюер спросил у Сьюзан, не занималась ли она сексом с животными, она с трудом удержалась, чтобы не выбежать из кабинета, но, так или иначе, верх взяли любопытство, перспектива работы на самом острие теории кодирования, возможность попасть во Дворец головоломок и стать членом наиболее секретного клуба в мире - Агентства национальной безопасности. Беккер внимательно слушал ее рассказ.
