Star topology

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.

Advantages and disadvantages of a star network

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.

Which is an example of star topology?

So, we connect our laptops, tablet PCs and Smartphones to the Wireless Modem for accessing the Internet. Hence, all our devices connect to a single central device known as Hub. So, this is probably the best Example of Star Topology.

What is the function of star 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.

Why is star topology used in LAN?

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.

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.

Where is star topology used in real life?

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.

Where are star topologies 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.

What is star topology explain with diagram?

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. The hub and hosts, and the transmission lines between them, form a graph with the topology of a star.

What is a star topology simple definition?

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.

What is one drawback of a star topology compared with a bus topology?

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.

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 ring and star topology?

The main difference between star and ring topology is that a star topology connects all the devices to a one central device forming a structure similar to a star while ring topology connects every device to another two devices forming a structure similar to a ring.

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 the difference between star topology 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.
