Slide 1Network TopologyMade By-Gaurav YadavClass - X - DNetwork TopologyPhysical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical designTypes Of Physical TopologyBus TopologyStar TopologyRing TopologyTree TopologyMesh TopologyBus TopologyA linear bus topology consists of a main run of cable with a terminator at each end. All servers workstations and peripherals are connected to the linear cableAdvantages Easy to install and use.Cables are less used then star or ring topology.Disadvantages-Disorder in any node may lead to failure of entire data transmission.It is difficult to add a new node to the structure.Bus TopologyStar TopologyA star network is designed with each node (file server, workstation, peripheral) connected directly to a central network hub or server. Advantages An advantage of the star topology is the simplicity of adding additional nodes.Good option for modern networksLow startup costsEasy to manageDisadvantages-Hub is a single point of failureRequires more cable than the busStar TopologyRing TopologyA ring network is one where all workstations and other devices are connected in a continuous loop. There is no central server. A network topology that is set up in a circular fashion in which data travels around the ring in one direction and each device on the ring acts as a repeater to keep the signal strong as it travelsAdvantages-Easier to manage; easier to locate a defective node or cable problemHandles high-volume network trafficEnables reliable communicationDisadvantage-ExpensiveRequires more cable and network equipment at the startRing TopologyTree TopologyThis particular type of network topology is based on a hierarchy of nodes. The highest level of any tree network consists of a single, 'root' node, this node connected either a single (or, more commonly, multiple) node(s) in the level below by (a) point-to-point link(s)Advantages It is scalable. Secondary nodes allow more devices to be connected to a central node. Point to point connection of devices. Having different levels of the network makes it more manageable hence easier fault identification and isolation.Disadvantages-Maintenance of the network may be an issue when the network spans a great area.Since it is a variation of bus topology, if the backbone fails, the entire network is crippled.Tree TopologyMesh TopologyIt is also known as graph topology. In this topology each node is connected in another node Directly". So there is a mesh in the network as there are so many wires that are connected to each and every node.Fully Connected- A fully connected network is a communication network in which each of the nodes is connected to each other. A fully connected network doesn't need to use switching nor broadcasting.Partially Connected- The type of network topology in which some of the nodes of the network are connected to more than one other node in the network with a point-to-point link. Mesh Topology Fully PartiallyM.C.QPhysical topology have _____ no. of topologies?(a)Five (b)TwoAns. (a)Five In case of failure of one node in ring topology the whole system crashes(a)True (b)FalseAns. (b)FalseIf hub fails then whole network fails.a)True (b)FalseAns. (a)TrueMesh topology is of _______ types.(a)three (b)twoAns. (b)twoBus topology is _____________(a)Expensive (b)cheapAns. (b)Cheap _______ topology require more cable than Bus topology(a)Star (b)RingAns. (a)Star In ______topology each node is connected to a single cable?(a)Bus (b)RingAns.(a)Bus Token passing is used in ________ topology?(a)Star (b)RingAns.(b)RingTopology is divide in _____ types in accordance with the transmission method(a)three (b)twoAns.
