Why would you use a star topology?

Star topology is used to ease the probabilities of network failure by connecting all of the systems to a central node. In contrast to the bus topology, the star topology allows each machine on the network to have a point to point connection to the central hub and there is no single point of failure.

Simply so, what are the advantages and disadvantages of a 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.

Likewise, what is a star bus topology? Star Bus is a networking topology in which hubs for workgroups or departmental local area networks (LANs) are connected by using a network bus to form a single network. You can connect hubs by using one of the following: Regular 10Base2 or 10BaseT cables with uplink ports on the hubs.

In this way, why star topology is more reliable?

Star topology: In this type of network, a central computer (server) usually forms the main node and the subsidiary nodes are connected to it and to each other through a switch or hub. Advantages: The most reliable because the failure of a node or a node cable does not affect other nodes.

What are the key features of star topology?

Characteristics of a star topology are as follows: All cables run to a central connection point. If one cable breaks or fails, only the computer that is connected to that cable is unable to use the network. A star topology is scalable.

What are the advantages of tree topology?

Advantages of tree topology:

Scalable as leaf nodes can accommodate more nodes in the hierarchical chain. A point to point wiring to the central hub at each intermediate node of a tree topology represents a node in the bus topology. Other hierarchical networks are not affected if one of them gets damaged.

What are the 5 network topologies?

Computer Network Topology – Mesh, Star, Bus, Ring and Hybrid

There are five types of topology in computer networks:
In mesh topology each device is connected to every other device on the network through a dedicated point-to-point link.
In star topology each device in the network is connected to a central device called hub.

What is star topology with diagram?

Star Topology

Star Topology Diagram. In the star topology, all the computers connect with the help of a hub. This cable is called a central node, and all other nodes are connected using this central node. It is most popular on LAN networks as they are inexpensive and easy to install.

Which topology is best Why give reasons?

Advantage: Dedicated connection for all workstations. Disadvantage: The more wires required for each connection. 2) Star Topology: All workstations are connected to the central switch or hub. Advantage: Other workstations can connect easily without affecting rest of the network.

How does a star topology work?

Star topology. 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.

Where is star topology used?

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.

What do u mean by topology?

In networking, topology refers to the layout of a computer network. Topology can be described either physically or logically. Physical topology means the placement of the elements of the network, including the location of the devices or the layout of the cables.

Which topology is the fastest?

star topology

Which topology is best?

A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

Which topology has highest reliability?

mesh topology

Which topology is best for schools?

Star networks are usually the layout of choice in schools and offices because they tend to be the most reliable of the topologies.

Which topology is best for large networks?

Tree Topology

Main Advantage: A Tree topology is a good choice for large computer networks as the tree topology "divides" the whole network into parts that are more easily manageable. Main Disadvantage: The entire network depends on a central hub and a failure of the central hub can cripple the whole network.

What is a fully connected topology?

A fully connected network, complete topology, or full mesh topology is a network topology in which there is a direct link between all pairs of nodes.

Which topology is difficult to expand?

A mesh topology requires that every device be connected to every other device on the network. It is, therefore, quite difficult to expand a mesh network.

What are two reasons why you may have chosen to use a star network 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 are the 4 types of topology?

There are four categories: Star topology, Bus topology, Ring topology and Mesh topology. Hybrid combinations of these topologies also exist. Star topology – all computers and devices are connected to a main hub or switch. Star topology is the most common type of network and follows the Ethernet standard.

What is topology simple words?

Network Topology. A network topology describes the arrangement of systems on a computer network. It defines how the computers, or nodes, within the network are arranged and connected to each other. Some common network topologies include star, ring, line, bus, and tree configurations.
