what does cluster mean
A cluster is basically a group of things that are close together in space, time, or similarity.
Core meaning
- In everyday English, cluster means a group of similar things or people that are near each other, like a cluster of houses or a cluster of stars.
- As a verb, to cluster means to come together in a group, like people clustering around a stage.
“A cluster is a bunch of similar things packed together, instead of spread out.”

Quick mental picture
If you imagine dots on a page , a cluster is where lots of dots are crowded in one area while other areas are emptier. That same idea (things bunching together) is what “cluster” means in most situations.
TL;DR: Cluster = a group of similar things close together, whether they’re people, stars, data points, or computers.
