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. In a star network, every host is connected to a central hub, forming a graph with the topology of a star. Data on a star network passes through the hub before continuing to its destination, and the hub manages and controls all functions of the network. The star topology is one of the most common computer network topologies.
Advantages of star topology include centralized management of the network through the use of the central computer, hub, or switch, and the ease of adding another computer to the network. If one computer on the network fails, the rest of the network will not be affected. However, network performance can decrease as more computers are connected, resulting in slower network speeds.
Some applications of star topology include LANs, WANs, and the internet. Star topology can be implemented using wireless routers, Ethernet/cabled structures, and other components.
In summary, star topology is a network topology in which each device is connected to a central hub, forming a graph with the topology of a star. It is one of the most common computer network topologies and has advantages such as centralized management and ease of adding another computer to the network.
