What is a network topology?

In Computer technology, a network topology can be defined as the graphical representation of the various networking devices that are used to create and manage a network connection.

What are the types of topology?

In Computer networking, there are six (6) main types of network topology and these include the following:

  1. Ring topology
  2. Mesh topology
  3. Tree topology
  4. Hybrid topology
  5. Star topology
  6. Bus topology

Generally speaking, an Ethernet star local area network (LAN) simply refers to a type of network topology in which all of the network devices are directly connected to a common hub (centralized computer) or hub-and-spoke and it can be implemented by using a self-programming switch that is installed at the center of the star.
