As long as the noise does not cause the signal to exceed a certain threshold, the hub may replicate each bit, thus eliminating the noise. Each device was attached to it by a separate UTP cable that connected to one of the hub’s ports.Ī signal will have picked up some noise on its journey to the hub. The Ethernet Hubīus topology has been phased out in favor of star topology, which features a central connection point. In this stage, we’ll look at what a hub or switch does in a star network. In a star topology, two nodes may be physically separated from each other however, they must communicate through a central node. The performance of the link is determined by the performance of the central hub. The central site is vital in a star topology if it fails, all of the connections fail. Each node is directly connected to a central device, such as a hub or switch. ARCNET popularized the star, which was later adopted by Ethernet. What Device Is Used to Create a Physical Star Topologyįor LANs, star topology has become the dominant physical structure.
