Star topology

Alternatively called a star network, star topology is one of the most common network setups. In this configuration, every node, such as a hub, switch, or computer, connects to a central network device. Essentially, the central network device acts as a server, and the peripheral devices act as clients.

In a star topology setup, either a coaxial or a network cable with an RJ-45 connector is used, depending on each device's network card type. The image shows how this network setup gets its name, as it is shaped like a star.

There technically is no limit to how many computers can connect in a star topology. However, network performance can decrease with more connected devices, resulting in slower data transfer speeds.

Advantages of star topology

  • Centralized management of the network using a computer, hub, or switch.
  • Easier to add another computer to the network using this configuration.
  • If one computer on the network fails, the rest of the network continues to function normally.

Disadvantages of star topology

  • It may have a higher cost to implement, especially when using a switch or router as the central network device.
  • The central network device determines the performance and number of nodes the network can handle.
  • If the central computer, hub, or switch fails, the entire network goes down, and all computers are disconnected from the network.
