The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub. Each host may thus communicate with all others by transmitting to, and receiving from, the hub.
What is the main advantage of star topology?
The advantages of a star network are: it is very reliable – if one cable or device fails then all the others will continue to work. it is high-performing as no data collisions can occur.
What is the function of bus topology?
A bus topology connects computers along a single or more cable to connect linearly as figure 1. A network that uses a bus topology is referred to as a “bus network” which was the original form of Ethernet networks.
What is star topology short answer?
Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients.
What is the advantage of star topology compared to bus network?
A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, just one node is going to be brought down. Each device within the network is connected to a central device called hub.
What is computer star topology?
A star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies.

What is star in networking?
A star network is a local area network (LAN) topology in which all nodes — personal computers (PCs), workstations or other devices — are directly connected to a common central computer that is often referred to as a hub. Therefore, a star network is often referred to as a hub-and-spoke network topology.
What is the difference between star and tree topology?
Star topology is a topology in which the nodes are connected to the central hub or router. Tree topology is a topology in which the nodes are organized in the form of a tree. 2. In star topology, the communication between nodes are done through central node i.e., hub or router.
What is star topology class 10?
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. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down. Star topology.
Why is it called star topology?
Alternatively referred to as a star network, star topology is one of the most common network setups. In this configuration, every node connects to a central network device, like a hub, switch, or computer. … The image shows how this network setup gets its name, as it is shaped like a star.
What is topology explain bus and star topologies?
Star topology is a topology in which all devices are connected to a central hub. Bus topology is a topology where each device is connected to a single cable which is known as the backbone. 2. In star topology, if the central hub fails then the whole network fails.
What is the advantage and disadvantages of star topology?
Comparison Table for Advantages &, Disadvantages of Star Topology
| Advantages | Disadvantages |
|---|---|
| Highly scalable network | High dependency on the central device |
| Highly efficient | Expensive |
| Centralized network management | Requires additional equipment |
| Safe to use | Immobile systems |
Which of the following is used in star topology?
Answer: Hub is use in the star topology.
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.
Is star topology point-to-point?
Star Topology
This topology is a point-to-point connection topology where each node is dedicatedly connected to the hub. Hub is the central controller that connects all the devices in the network. The devices are not connected directly in this topology.
How is a star topology set up?
With a star topology setup, each node (such as a computer) within your company or team connects to one central network device (which could be a hub, a switch, or a computer) via a cable. The central network is the server, and the other devices are clients.
Which network uses bus ring and star topology?
Summary
| Topology | What it is |
|---|---|
| P2P | The network consists of a direct link between two computers |
| Bus | Uses a single cable which connects all the included nodes |
| Ring | Every device has exactly two neighboring devices for communication purpose |
| Star | All the computers connect with the help of a hub. |
What is the difference between star topology and mesh topology?
In star topology, the nodes are connected to the central hub or router. In mesh topology, the nodes are connected to each other completely via dedicated link.
What is star configuration?
In a star configuration all three phase conductors of a three-phase system are electrically connected at one end. The resulting connection, which forms the centre point, is referred to as star point. The free ends are connected to the external conductors (L1, L2, and L3). …
What is star topology Javatpoint?
Star topology is an arrangement of the network in which every node is connected to the central hub, switch or a central computer. The central computer is known as a server, and the peripheral devices attached to the server are known as clients.
How does star topology work why star topology is the best topology?
Star topologies provide an inherent advantage that a new site can be added with ease, only the central site will have to be updated. In star topology, the central site plays an important role, if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection.
What is the main difference between star and bus topology?
Difference between Star topology and Bus topology
| Star topology | Bus topology |
|---|---|
| A central hub connects all the devices. | Each device is connected to the backbone, which is a single cable. |
| If the central hub fails, the entire network will fail. | The failure of a network cable will result in the failure of the entire 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.
Is WiFi a star topology?
However, wireless networks use only two logical topologies: Star—The star topology, used by Wi-Fi/IEEE 802.11–based products in the infrastructure mode, resembles the topology used by 10BASE-T and faster versions of Ethernet that use a switch (or hub).
How does a star wired bus topology work?
Working of Star Bus Topology
In a star bus network, every single host is linked to a central medium called a hub, whereas it acts as the head of the network and manages all the connections established through the network and data flow between transmission and reception of the nodes connected in the network.
Is WiFi a star network?
Star Topology
In fact, a majority of low power, wide-area network (LPWAN) technologies, in addition to WiFi and cellular networks, use a star network topology. A star network has a router or access point in the middle that connects to all the terminals or nodes.
How do star topology connect with computers?
In star topology, each computer is connected to a central hub using a point-to-point connection. The central hub can be a computer server that manages the network, or it can be a much simpler device that only makes the connections between computers over the network possible.
