A computer network topology refers to the way in which devices on a network are connected and the layout of these connections. Two common types of network topologies are star and bus.
In a star topology, each device on the network is connected to a central hub or switch. The hub or switch serves as the central point of communication for all devices on the network and acts as a traffic controller, directing data to its intended destination.
One of the main advantages of a star topology is its reliability. Because each device has its own dedicated connection to the hub, if one device fails, it does not affect the rest of the network. In contrast, in a bus topology, all devices are connected to a single central cable, called a bus. If the bus fails, the entire network goes down.
Another advantage of a star topology is its simplicity. It is easy to add or remove devices from the network because each device has its own connection to the hub. In a bus topology, adding or removing a device requires reconfiguring the entire network.
In terms of performance, a star topology generally provides faster data transfer speeds compared to a bus topology. This is because the hub or switch can manage the flow of data and ensure that it is being transmitted efficiently. In a bus topology, data transmission can be slowed down if there are too many devices connected to the bus.
In terms of security, a star topology also has an advantage over a bus topology. Because each device has its own connection to the hub, it is more difficult for unauthorized devices to access the network. In a bus topology, any device connected to the bus can potentially access the network.
Overall, the star topology has several advantages over the bus topology, including increased reliability, simplicity, performance, and security. While both topologies have their own set of benefits, the star topology is generally a more effective choice for a computer network.
15 Advantages and Disadvantages of Star Topology
Bus topology definition is, this is one of the simplest physical topology used for the network. In this kind of topology, a centralized node is located at the core of the network topology, in which all the other nodes must communicate through. This has brought about the evolution of computer networking to include more devices, which will further enhance the process of information sharing across different geographical locations. The terminators that are used for most bus topology systems are passive devices. Why star topology is used in LAN? However, the orientation of the star network is non-linear. The network adopts the characteristics and functioning of the combined topologies,rather than just the one. If a failure happens for any reason, then all of the devices connected to it will not receive a network connection.
What are advantages and disadvantages of star topology over bus topology?
In a bus topology, one computer in the network works as a server and other computers behave as clients. What is bus topology?

In star topology, the nodes are connected to the central hub or router. However, bus topology can be easily installed as a single link is required. What is the difference between star and ring topology? What are the advantages and disadvantages of star topology? The restriction on available bandwidth in a bus is not due to the speed of individual devices but rather the number of devices on the network, which creates a bottleneck. This is not efficient. Individual device issues can also be difficult to troubleshoot, which means it is not a great setup for larger networks. In computer networks, there are mainly two types of topologies, they are: Physical Topology: A physical topology describes the way in which the computers or nodes are connected with each other in a computer network.
