Network TopologyMade By-Gaurav YadavClass - X - D

Network 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 design

Types Of Physical TopologyBus TopologyStar TopologyRing TopologyTree TopologyMesh Topology

Bus 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 cable

Advantages

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 Topology

Star 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 manage

Disadvantages-Hub is a single point of failureRequires more cable than the bus

Star Topology

Ring 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 travels

Advantages-

Easier to manage; easier to locate a defective node or cable problemHandles high-volume network trafficEnables reliable communication

Disadvantage-

ExpensiveRequires more cable and network equipment at the start

Ring Topology

Tree 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 Topology

Mesh 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.
