What is star topology with example?

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 topologies tend to be found in large organisations, such as educational establishments and businesses, where high performance is a must. They are also found in home networks, especially those that are wireless. In this case, a router with a wireless access point (WAP) provides the central connection for all nodes.

Why star topology is commonly used?

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.

What is star topology class 10?

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. ... When the central node receives a packet from a connecting node, it can pass the packet on to other nodes in the network. A star topology is also known as a star network.

Why hub is used in star topology?

Data on a star network passes through the hub before continuing to its destination. The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.

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.

How many cables are needed in star topology?

a Advantages of this topology :

If N devices are connected to each other in a star topology, then the number of cables required to connect them is N. So, it is easy to set up. Each device requires only 1 port i.e. to connect to the hub, therefore the total number of ports required is N.

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 difference between bus topology and star topology?

Differences between Star Topology and Bus Topology:

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.

Can we use switch in star topology?

In a star topology, each network node is connected to a central device called a hub or a switch. ... Strictly speaking, only networks that use switches have a true star topology. If the network uses a hub, the network topology has the physical appearance of a star, but is actually a bus.

What hardware is needed for a star topology?

The center of the star uses a multiport connecting device that can be either a hub or a switch. Although both hubs and switches can connect the network—and can have several features in common—only switches are normally used today.

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.

What happens if a host goes down in star topology?

What happens if a host goes down in a star topology? ... The downed host will not have a connection to the central hub, but all other devices can connect. The data will instead work downstream up to the break.

Which topology is fastest?

Theoretically the fastest topology should be mesh topology. But the best topology is star topology. In star topology devices are connected to the center switch or hub and all interconnection between them are done through that center hub.
