Is star topology good for LAN?

Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.

What topology are appropriate for LAN?

There are three common topologies found in LANs: star, ring, and bus. In a star topology, all devices on the LAN are interconnected through some central device.

What is the advantages 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.

Is star topology WAN or LAN?

Star. Star networks have nodes connected to a central hub like the spokes of a wheel (See Reference 4). In a star LAN, the hub will most likely be a network switch, while star WANs generally make use of a concentrator router. In addition, all traffic must be sent through the hub, which can create bottlenecks.

Why star topology is better than bus topology?

Star topology has high implementation cost because of central hub and extra wires required for connection. Bus topology is less expensive than star topology. 6. Data transmission is faster in star topology.

Is star topology point-to-point?

While mesh and star networks are used to connect multiple ‘things’ to a network, point-to-point topology is used to connect two things together.

What is star in network topology?

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.

Which is the most widely used topology in LAN?

Star topology
Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape.

What are the advantages and disadvantages of star network topology?

Comparison Table for Advantages & Disadvantages of Star Topology

Is star topology point to point?

Which topology is better star or bus?

When there is a need for a wide network, then bus topology is preferred. This is so because it supports the easy addition of various devices in the network. While in star topology addition of devices is limited. The structure of the bus network is linear as various devices are connected through a straight cable.

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.
