What are the advantages and disadvantages of extended star topology?
Advantages and disadvantages of a star network
- it is expensive to install as this type of network uses the most cable (network cable is expensive)
- extra hardware is required (hubs or switches) which adds to cost.
- if a hub or switch fails, all the devices connected to it will have no network connection.
What is the extended form of star topology?
A hierarchical or extended star topology is a star network with an additional networking device connected to the main networking device. Typically, a network cable connects to one switch, and then several other switches connect to the first switch.
Why star topology is commonly used?
Answer: In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network. Star topology is used to ease the probabilities of network failure by connecting all of the systems to a central node.
Where star topology is used in real life?
Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub. Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed.
Why star topology is used in LAN?
A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. The main advantages of a star network is that one malfunctioning node does not affect the rest of the network.
What is a benefit of a mesh network over a star network?
The primary advantage of mesh topology is that it has low transmit power and shorter links (< 100 ft), which allows for a fairly long battery life and enables you to move a lot of data around the network. The primary disadvantage of mesh topology is that the range between two mesh nodes is quite limited.
What type of device is at the center of the extended star?
An extended star should be used with a switch as the central device. Will the network be peer-to-peer or server-based? The discussion of EBiz.com’s requirements mentions five existing servers, without requiring the introduction of new servers, so this implementation obviously involves a server-based network.
What are the advantages of a logical star topology over the logical bus topology?
what are the advantages of the logical star topology over the logical bus topology? – All the data goes through the central point Which can be equipped with diagnostic devices Which makes it easy to troubleshoot.
What are the advantages of star topology over bus topology?
Advantages of Star Topology
- Easy to install and wire.
- No disruptions to the network when connecting or removing devices.
- Requires more cable length than a linear bus topology.
- If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.
What cable is used in star topology?
In a star topology setup, either a coaxial or RJ-45 network cable is used, depending on the type of network card installed in each computer.
Which device is used in star topology?
A star topology is the most commonly used network configuration. In this type of topology, nodes are connected to a central device like a switch or a hub with the help of coaxial cable, optical fiber, or twisted pair cable.
What are real life applications and uses of network mesh topology?
Mesh topology is a type of networking where all nodes cooperate to distribute data amongst each other. This topology was originally developed 30+ years ago for military applications, but today, they are typically used for things like home automation, smart HVAC control, and smart buildings.
Why star topology is best?
A star network topology has many advantages. The star network is easy to install and wire. This topology type gives a better performance than any other network topology as there is no clogging of nodes. In order to communicate between any two devices only 2 links and 3 devices are involved to prevent confusion.
Which topology is expensive?
In Mesh Topology , all the computers are inter-connected to each other in a network. Each computer not only sends its own signals but also relays data from other computers. This type of topology is very expensive as Its very difficult to establish the connections of the mesh topology.
What is the best type of topology?
The best topology is ring topology. Star is the next best after ringr, and then bus, which is pretty old, but not too expensive. Full mesh topology is theoretically the best since every device is. connected to every other device, thus maximizing speed and security.
What are the uses of star topology?
Centralization. Hub/Switches acts as a central monitoring agency on the performance of the individual nodes and glitches in the performance can be easily tracked and rectified.
