Star Network Topology
Star Network Topology Diagram
Star networks are well known for their nodes being located in a shape of a star. There are one of the most commonly used computer network topologies – star network topologies. The way such networks look reminds of a star as there is a central node which is illustrated in the very middle of the network schematics and from this central hub there are other nodes all around this hub connected to it. The central hub is there to transmit the messages to the other nodes and it is the server itself when the peripheral nodes are the clients.
Having such hub as well as the leaf nodes which are connected to it all together with the transmission lines between all of them, you can illustrate all that in a way of a network topology which will be called the start network topology diagram. In this diagram of a star form everyone can clearly see both the central hub, the nodes and the lines which connect these nodes to the middle where the hub is. The data is meant to be going through the hub, or the switch (also known as concentrator), before it can finish its way until it gets to its destination.
The main function of the hub is to control and message all of the functions of the network. It can also be in charge for repeating the data flow. Such configuration can be made with use of the twisted pair cable as well as the optical fibre cable. A coaxial cable can also be used.
The reason of using the star topology is to reduce the impact of a failure for a line in a way of connecting all existing systems to one central node or hub. All of the peripheral, but central, nodes can be connected with each other only through the very central node which is the hub in the middle of the star topology drawing. They all transmit and receive data only in a way of using the central node, there is no other way of their communication.
In case there is a failure of a transmission line which links any of the peripheral nodes to the very central node, it will lead to a result of the isolation of that peripheral node from all other nodes. In this case all of the rest of the systems will not be affected.
If you work in IT or you, for some reason, want to illustrate the way star network topology looks like and you want to make this drawing look truly professional, then you might spend long hours trying to create it yourself. Although, there exists another option. If you find the right software to be able to use it in order to create such great looking, smart, professional star network topology diagram, then it can be much simpler to finish with your drawing and so quicker.

In case you decide to get one of the solutions after downloading ConceptDraw DIAGRAM you can always download them either rom the ConceptDraw STORE (which is another product of CS Odessa), or this site. Each of the solutions provide at least one library with the stencils that can be used for making so many different charts, plans, schemes, flowcharts and diagrams, including the star network topology ones.
Having them means having pretty much everything you need to make it happen – to make a smart looking star network topology diagram from a scratch using Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park which provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment.
You can always use it to draw the physical and logical network topology diagrams for wired and wireless computer communication networks, including the extended star and the distributed star.
Extended star is a type of network topology, where a network, based upon the physical star topology, has one or more repeaters between the central node which also can be called the “hub” of the “star”. In this network topology the peripheral or so called “spoke” nodes, the repeaters, are being used for extending the maximum transmission distance of the point-to-point links between the central node and the peripheral nodes. In case these repeaters are replaced with hubs or switches, then so called hybrid network topology is created.
Distributed Star is a commonly used type of network topology that has individual networks based on the physical star topology and connected in a linear fashion with no central or top level connection point.

TEN RELATED HOW TO's:Physical network represents the computer network topology that includes the computer devices, location and cable installation. Physical network includes the actual nodes, segments and hosts. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Physical star network.
Picture: Physical network. Computer and Network ExamplesRelated Solution:When talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems. The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.
Picture: Network Glossary DefinitionRelated Solution:Every corporate network is unique, though there are guidelines and best practices in developing networks. As it is quite difficult to implement a pure topology within a company, using a hybrid network topology is considered a better solution. As a rule, such network assembles advantages and features of source topologies. This diagram is an example of the Hybrid network. This type of network topology means a conjunction of other network topologies. Such as star-bus, ring-mesh topologies, etc. It should be obviously diverse networks. The final computer network inherits both advantages and disadvantages of its ingredients. Using the ConceptDraw Computer and Networks solution including vector graphic libraries and templates one can develop professional custom network diagrams of any topology and complexity.

A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks. Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.
Picture: Metropolitan area networks (MAN). Computer and Network ExamplesRelated Solution:Every engineering project starts from a terms of reference document. The next stage of developing is a technical drawing, which requires using appropriate software. However, revisions and discussions about requirements are possible at any stage of development. This technical drawing demonstrates a schematic flow diagram of pulp reclaiming. This diagram of magnetite pulp reclaiming is created using ConceptDraw Chemical and Process engineering solution, The solution delivers more than 460 vector graphic icons and connectors. Generally, it is intended for designing process and instrumentation diagrams (P&ID) for chemical and process engineering. block flow diagrams (BFD), process flow diagrams (PFD) for chemical industry.
Picture: Technical Drawing SoftwareRelated Solution:When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.
