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 topology, the central hub acts like a server and the connecting nodes act like clients.

How many servers can be in a cluster?

Those who have experienced the complexities and gotchas of two-node clusters know that a minimum of three servers is the best way to create a cluster that is both reliable and easy to manage.

Which are the two types of clustering?

There are two different types of clustering, which are hierarchical and non-hierarchical methods.

  • Non-hierarchical Clustering. In this method, the dataset containing N objects is divided into M clusters.
  • Hierarchical Clustering. In this method, a set of nested clusters are produced.
