What Is Star Bus Topology?

Why star 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..

What means topology?

In mathematics, topology (from the Greek words τόπος, ‘place, location’, and λόγος, ‘study’) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling and bending, but not tearing or gluing.

What are advantages and disadvantages of star topology?

Advantages and disadvantages of a star networkit 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.

Where are star topologies used?

Star topologies are used in many networks, large and small. In a star topology all nodes indirectly connect to each other through one or more switches . The switch acts as a central point through which all communications are passed. Large networks using a star topology are usually controlled by one or more servers .

What is bus topology with example?

An example of bus topology is connecting two floors through a single line. Ethernet networks also use a bus topology. In a bus topology, one computer in the network works as a server and other computers behave as clients. The purpose of the server is to exchange data between client computers.

What is bus topology with diagram?

Alternatively referred to as line topology, bus topology is a network setup where each computer and network device is connected to a single cable or backbone. … The following sections contain both the advantages and disadvantages of using a bus topology with your devices.

What are the examples of star topology?

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 is a bus topology?

A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus.

How is star topology better than bus topology?

The crucial difference between bus and star topology is that bus topology uses a single cable through which various peripheral devices are connected. … As against a star topology makes use of central hub or switch that broadcasts information to all the devices in the network.

What is hybrid topology?

Hybrid topology is an integration of two or more different topologies to form a resultant topology which has many advantages (as well as disadvantages) of all the constituent basic topologies rather than having characteristics of one specific topology.

What is a 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.

Which topology is fastest?

But in mesh topology each devices are connected to other devices directly by individual cables without using center hub. Theoretically the fastest topology should be mesh topology. But the best topology is star topology.

How is star topology connected?

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.

Which topology is the cheapest?

The star and extended star are the most popular topologies for Ethernet networks. This type network is easy to setup, relatively inexpensive, and provides more redundancy than other topologies, i.e. bus topology. The star topology is configured by connecting all of the nodes on the network to central device.
