star topology examples

In establishing a typical Star Network Topology you can use Hub or Switch. star topology. Also, server i.e. A combination of two or more topology is known as hybrid topology. The hub works as a server and it controls and manages entire function of the network. You require a lot of capital expense to establish this setup as you have to purchase considerable amount of wire. You can think of topology as the virtual shape or structure of the network. There are a certain number of hardware equipment that is required as Star Topology Hardware. Problem diagnosis and troubleshooting is easy because of individual point-to-point connections. Mesh Network Topology requires extensive amount of cabling because you need to connect one Node with all other Nodes on a network through a dedicated link. nodes that are connected are known as clients. Star Topology. The working mechanism is very simple one. An Active Hub works as a repeater. It is more secure when compared to other types of topological structures. How long have you been working in this field? This main cable or bus forms a common medium of communication which any device may tap into or attach itself to via an interface connector. This topology is frequently used for networks in which control of the network is located in the central node. For imposing a limit on number of users, you have to perform manual settings and if you are not technically sound you may feel difficulties. Instead sender sends data to the central hub. Then is a topology called the Sierpinski topology after … Such setups look neat and clean because there are no messy cables. See you again with a new topic. Your email address will not be published. I am a blogger and freelance web developer by profession. Wow, incredible article! A hub maybe a hub, a router or a switch.. It is preferred by most of Network Specialists because it is easily extendable. The performance of the network is dependent upon the If the destination address and address of a Node matches then the matching one keeps the message. We will purchase an additional Hub (four ports or more) or Switch as we want to facilitate six users. I will thoroughly explain advantages and disadvantages of each one for the sake of your understanding. You might also have noticed a bunch of cable coming out of the box. A patch cable connects each individual device to the central Hub. For establishing high speed Computer Networks you can even use Fiber Optic Cable. I am going to explain each one in detail in the coming section. Extended Star Topology comprises of with multiple Hubs or Switches. Star Network Topology using Switch should be your first choice as it is intelligent in terms of routing, destination identification and regeneration. One of the main quality of this one is that it exists in both wired and wireless forms (I will explain these in further coming sections). Each topology provides you with some features and drawbacks. It is basically the same concept that we use with USB devices. But after receiving the data message, the Switch itself checks the destination address. stop working. Although it is being still used in many organizations. In this type of scenario, each device in the Network has a Wired LAN Card. Now its the time to elaborate this Type of Network Topology with the help of real life examples. hub, switch, the router is expensive in cost in the star topology. - Intelligent Hub or Switch Definition, In Passive Star Network Topology, Passive Hub receives the message and broadcasts it without any processing, Active Hub receives the message, processes/regenerates it and broadcasts it, Switch/Intelligent Hub receives the message, processes/regenerates it and uni-casts it, What is Star Topology? This means that we can connect maximum of four devices in this Computer Network. The client server network exists between the central & peripheral devices. The cables So according to working mechanism, we can divide Star Topology in further three different types: However, in all these three cases the Star Topology Layout is the same. However, if you create a schematic diagram of this Type of Topology then you will virtually draw a Hub or Switch in the middle. There are no chances of signal reflection in it. In fact, an Active Hub receives sender communication signals, reprocess/regenerate the signals and broadcast to all other Nodes in the Computer Network. (For more details you can refer to Example 2). In this way, an Active Hub also serves the purpose of a Repeater as well. This discipline examines the configurati… Star topologies are used in many networks, large and small. However, in Star Topology Network, you only need one point-to-point wire for connecting a Node to all other Nodes in the Network. A star takes more cable than e.g. Star Topology saves Data if there is a failure in Network so you can Backup data’s and files from Computer. Hence, all the device connect to the central device with the help of wireless signals preferably WiFi technology. Definition | Advantages | Disadvantages, How to Create Bus Topology in Cisco Packet Tracer-[Beginner’s Tutorial], Computer Communication Networks Basics that You Must Know, How to Make Star Topology in Cisco Packet Tracer? I hope that up to now you people might have understood all the concepts that I have tried to explain. You have noticed that I have talked a lot about the flexibility and extension of Computer Network. So here we are. When anybody wants to connect to the Internet there is no restriction on him/her in terms of location. This will help you to understand it in a much better way. I am working as Network Administrator in NYC. All you need is just to find or create an empty port in the Hub or the Switch. In Star Topology, all the Network Nodes like Clients, Servers and other Network Devices like printers, scanners, switches connect to a central device. to another node then switch knows which node to send a message to as it has a copy Star topology. If I talk about the Physical Topology of Star Network, then it simply comprises of a central device referred as Hub and all the Network Nodes run wires to this central device. Node whose address is not same as that of destination discards the data message. No two devices configured in star topology can communicate directly. that are used to connect nodes include optical fibre, twisted pair cable, RJ-45 Suppose we want to connect six Nodes. You can create network topology examples like this bus network using SmartDraw's extensive collection of network design symbols. Signal regeneration results in increasing the strength of communication signal. This hub is the central node and all others nodes are connected to the central node. When you use a Passive Hub in your Star Network, the central device receives data message from the sender. Draw Network Topology and Computer Network Diagrams, Designs, Schematics, and Network Maps using ConceptDraw in no Time! of all the addresses. These are the devices where the cables from individual nodes are plugged in. Instead it reads the destination address of data message and transmits it to the intended receiver. Although the physical layout of this topology is not actually like a star. Each node (computer) in the network has some unique address If only two endpoints form a network by connecting to a single cable, this is known as a linear bus topology. By comparison you can infer that Star Topology Benefits are far more promising. Definition | Examples | Advantages | Disadvantages. You may also use a Switch as a central device. Finite examples Finite sets can have many topologies on them. In a star network each device on the network has its own cable that connects to a switch or hub. Star Topology, undoubtedly is the most common network topology.It is one of the most used network layout being used in banks, educational institutes, offices, schools and other organizations.
