Why is it called star topology?

Alternatively referred to as a star network, star topology is one of the most common network setups. In this configuration, every node connects to a central network device, like a hub, switch, or computer. The image shows how this network setup gets its name, as it is shaped like a star.

Why do we use 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.

What is the 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 star topology Javatpoint?

Star topology is an arrangement of the network in which every node is connected to the central hub, switch or a central computer. The central computer is known as a server, and the peripheral devices attached to the server are known as clients.

What is a star topology and its advantages and disadvantages?

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.

Where is a 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.

What is the logical topology?

Logical Topology is the arrangement of network devices and nodes to form a logical or physical structure. The logical topology deals with network protocols that are used to control the data flow across the network. The ethernet protocol is the most common protocol used for logical topology.

Why star topology is 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.

What are disadvantages of using a star topology?

Disadvantages of Star 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 network communication. • More expensive than linear bus topology because of the cost of the connecting devices (network switches).

What are the characteristics of the star topology?

Star topology. Star topology in use in a network. A Star network is one of the most common computer network topologies. In star topology, every host is connected to a central hub. In its simplest form one central hub acts as a conduit to transmit messages. A star network is an implementation of a spoke–hub distribution paradigm in computer networks.

What are the properties of star topology?

Some of the properties of star topology in points are: In Star topology break in a cable will only affect one computer. In star topology if hub fails then it can bring down the whole LAN. Star topology can be easily interconnected with other networks because of the central connection point. Star topology is one of the most popular type of topology for use within LANs.

Where does star topology usually used?

Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch.
