What is clustering in programming?

A cluster is a group of inter-connected computers or hosts that work together to support applications and middleware (e.g. databases). In a cluster, each computer is referred to as a “node”.

What is clustering and how it works?

Clustering is the task of dividing the population or data points into a number of groups such that data points in the same groups are more similar to other data points in the same group than those in other groups. In simple words, the aim is to segregate groups with similar traits and assign them into clusters.
